The purpose of this two part tutorial is to provide enough instruction, and explanation on Filestack’s Javascript API that someone inexperienced with either Filestack or Javascript can leave with a grasp on what we do, and how we do it. The first part will focus on basic HTML and Javascript, and implementing file uploads, and […]
On April 17, 2017, Filestack became compliant with the EU-US Privacy Shield framework. The EU-US Privacy Shield is a framework for transferring data between the United States and European Union that ensures the data falls within the EU privacy regulations. Privacy Shield replaces Safe Harbor to protect EU citizens’ data from US surveillance and address […]

As a printing application, the ability to upload pictures and create photo collages for your customers is an absolute must-have. The are a few open […]
We often recommend using Filestack to upload files. But why is Filestack really better than building your own file uploader from scratch? Does Filestack actually save you time and provide more capabilities? First things first… What is Filestack? If you’re not familiar with Filestack, it is an end-to-end file upload and management solution. Through our JavaScript […]
One of the coolest papers to come out of the deep learning renaissance has been A Neural Algorithm of Artistic Style. Presumably, it’s what drives Prisma, and it’s completely open to the world. Anyone can build their own neural filters if they have the time and inclination — which is exactly what we are going to do. Using […]
Taking screenshots is common for those of us who live on our phones and laptops. Sometimes we want to share glimpses of funny conversations with friends, other times, in the office for example, we take screenshots to quickly share unexpected results on our screens. Screenshots are so common that nowadays the majority of our devices offer a specific key […]
I have always been amazed by the upscale processes shown in action movies. Typically, a satellite photo captures the assumed location of the villain and the picture is infinitely zoomed while preserving a great amount of details. This works pretty well in fictional stories, but when you try to enlarge an image in real life, the result […]
With social media platforms like Facebook, Instagram, Snapchat and Twitter becoming staples in our lives, we regularly share moments in our lives through casual images on the web. Think about selfies: The simple term for a self-portrait photograph is a very common snapshot that invaded Facebook, Instagram and Twitter whose popularity is never decreasing. The fact […]
Only a few years after its name was coined, deep learning found itself at the forefront of the digital zeitgeist. Over the course of the past two decades, online services evolved into large-scale cloud platforms, while popular libraries like Tensorflow, Torch and Theano later made machine learning integration far simpler and more efficient. Algorithms deemed intractable […]
From fashion to print shops, Shopify is a great resource for building Ecommerce platforms. Shopify makes it easy to sell goods online – where you can showcase your store and have an online checkout option. However, we often hear clients ask, “How do I enable users to upload pictures to my Shopify store, for custom prints or clothing […]
There is no doubt Filestack is very popular when it comes to working with pictures, as there are loads of possibilities for customizing images. However, the API extends far beyond this: There are no constraints on the files one can upload, and the Filestack team kindly provides other functionalities: Video and Audio conversions for example. […]
Filestack comes with a rich set of features and gives clients total freedom in customizing its behavior. As developers, we can set constraints on the type of files a user can upload, their sizes, from what source a user is allowed to upload and so on. In addition to this, Filestack provides other functionalities through […]
Editor’s note: This is a guest post by Charles Ouellet, the Co-Founder & Lead Engineer of SnipCart. Here he demonstrates how to easily create an online ASCII poster store using Filestack and Snipcart. When we launched Snipcart, our shopping cart platform, we decided to build something we, as developers, would love to use. Something that would make our […]
The online video space just got a whole lot more interesting thanks to the recent battle between Meerkat and Periscope. While the focus may be on the flaws and pros of each service, there is one glaring factor that operators should be taking note of – the almost instant acceptance and use of both apps. Video […]
Nowadays, many people keep their files in the cloud. Not only for accessibility, but also for safety. For example, I have a Nexus 5, and when I take a picture, it will upload it to my Google account the next time I’m connected to wifi. Once it’s uploaded, I have access to it anywhere. Now […]
Filepicker has enabled millions of file uploads via Dropbox, from your users to your website or app. Previously, these files went through a shared Dropbox API key, but for enhanced security and comply with Dropbox’s new Terms of Service, we now require all developers to enter their own Dropbox credentials. This process will not impact […]
Browser-side Javascript is a lot of fun, but there’s a serious limitation when it comes to security because the source is publicly viewable. Given that one of the things we do here at Filepicker.io is provide a javascript library that helps developers upload files into their S3, it’s important that the developers have a way […]
The deal is paused on one question in the security review: “Can you show us who downloaded this file?” Not “Can you deliver it quickly?” Not “Does the link work?” Just that one question, and the answer can determine whether the quarter closes on time. Enterprise file delivery is judged twice: once by users measuring […]
A 4GB dataset download reaches 91% on hotel Wi-Fi. The connection drops for two seconds. The server says, “start over.” The user says, “support ticket,” and probably with a lot less patience the second time. Large file delivery fails quietly. A download that stalls at 91% and starts from zero is the result of a […]
The same invoice PDF produces a different total on Android than it does on the web. Support can’t reproduce the issue because both teams are using different OCR engines, and both implementations can be working correctly. The engines have simply changed at different rates over time. The goal of a cross-platform PDF data extraction SDK […]
An insurance adjuster photographs a claim form on a car hood, with bright sunlight overhead and one hand holding the paper down against the wind. What reaches the office next is either clean, structured data or a request for a retake that can cost two days while the adjuster is already on to the next […]
Most teams testing an OCR API usually do one of two things: trust the accuracy number provided by the vendor or test a few random documents and make a decision based on the results. But neither approach gives you a reliable accuracy number. If certain types of documents start failing in production, it can be […]
Each business idea below has a real buyer, an existing seller, and a version one person can launch on the free plan. Companies that already did it at a larger scale are worth reading first if you want to see where one of these ends up. We wrote every request to be copyable. Set HANDLE […]
Every Python OCR library does the same two things: find text in an image, and guess what it says. What separates them is how much of your machine they need, how they handle a page that is not a clean scan, and who maintains the model when accuracy drifts. This walks the three that people […]
Python gives you four realistic ways to extract text from a PDF, and choosing between them comes down to two questions: does the PDF already contain text, and do you need the layout back or just the words. Key takeaways Check for a text layer first, since a scan and a text PDF need different […]
Python OCR PDF work has one rule that saves most of the effort: only run recognition on the pages that need it. A PDF is a container, its pages can be text or images independently, and a twenty-page contract is often nineteen text pages and one scanned signature page. Recognising all twenty is slower, less […]
A PDF generation API is two different products sold under one phrase, and picking the wrong kind wastes a week. One renders a PDF from markup or a template you design. The other converts a file you already have into PDF. They share almost no implementation and almost no pricing model. Work out which you […]
Securing a React picker with signed policies takes one server endpoint and one prop. The endpoint signs a short-lived statement of what the client may do, the prop hands that statement to the picker, and your app secret never reaches the browser. The whole implementation is in filestack-snippets, as a small policy server and the […]
Every modern application serves images: product photos, user avatars, blog thumbnails, social previews. The problem is that each context demands a different size, format, or crop. Managing that manually doesn’t scale, and pre-generating every variant wastes storage and slows releases. An image-editing API solves this by handling transformations in code, at request time, with no […]
Every business deals with documents every day. Companies receive invoices in emails, store contracts in cloud folders, process patient forms, and verify ID documents during user onboarding. All these documents contain important information, but turning that information into usable data often takes a lot of manual work. A modern data extraction SDK helps automate this […]
Every day, businesses deal with a lot of paperwork, like invoices in emails, scanned forms, or ID photos. The data is there, but it’s stuck inside images, so it can’t be used directly. Someone still has to open each file and type the information manually. In today’s fast-moving digital world, this is a problem. Manual […]
Every day, companies handle millions of documents like invoices, contracts, patient forms, insurance claims, and shipping papers. But in many cases, people still have to read these documents and manually enter the data into systems. This isn’t just an IT issue. It directly affects how competitive a business is. McKinsey estimates that automating document workflows […]
Every file your app handles is basically part of a pipeline. Whether it’s a user uploading a profile photo, a customer sharing a PDF, or a platform processing hours of video, each action starts a chain of technical decisions. The issue is that most teams don’t notice what’s wrong until the app starts growing and […]
When people start talking about Intelligent Document Processing (IDP), the discussion often begins in the wrong way. Usually, the finance team asks: “How much does it cost to process each document?” The operations team asks: “How many people can we reduce?” Because of this, the project is often treated as just a way to save […]
Every day a new customer waits to be onboarded means lost time, lost revenue, and more room for doubt. The longer the process drags on, the more likely customers are to question whether they made the right decision in choosing your product. For technical leaders, customer onboarding with document automation is one of the clearest […]
When a team is asked to “quickly build a submission portal,” it sounds easy at first. You might think it will take just a couple of sprints. But once you start working on it, things get complicated. Handling file uploads in real life is not simple. You have to deal with big files like 300MB […]
If you’re building or scaling a learning management system, you’ve probably seen this: exam week arrives, thousands of students upload assignments at once, and the system starts to slow down or crash. Video processing delays document uploads. A failed virus scan blocks everything behind it. One bad file affects other students. When everything runs inside […]
When you add receipt scanning to your app, reading text from the receipt image is only the first step. The harder part comes next. The text you get is usually not perfect: Some numbers can be incorrect. Dates can be written in different formats. Item names can look weird or broken. So before you save […]
When you build a printing application, one of the first challenges you face is also one of the hardest to control. Users upload files in wildly different color spaces, formats, and quality levels. Whether it’s a design created on a phone in Display P3, a JPEG exported from Photoshop without an ICC profile, or a […]
If you’re a bootstrapped founder, you already know how fast infrastructure costs can get out of control. One of the biggest silent expenses? CDN bandwidth. It starts small. A few images. A handful of uploads. A couple of API calls from your growing user base. But as traffic scales, unoptimized images, large files, and unnecessary […]
For startups, every decision affects speed, scalability, and the bottom line. Choosing between CDN vs File Storage can feel like a tug-of-war between performance and cost. The truth? Both play vital roles—but in very different ways. While one stores your data securely, the other delivers it to users worldwide faster. Understanding how each works can […]
Startups today rely heavily on visual content. From product photos to marketing banners, images make websites and apps more engaging. But they also consume a huge amount of bandwidth. When every megabyte counts, high bandwidth costs can quickly eat into limited startup budgets. This is where image compression comes in. By reducing file size without […]
JavaScript isn’t just for building interactive buttons or flashy animations anymore—today, it’s powering full-fledged image editing experiences right in your browser. Whether you’re building a photo editor, user profile uploader, or a content creation tool, JavaScript image editing APIs give you the power to manipulate, transform, and optimize images without relying on bulky desktop software. […]

The guide builds the UI block-by-block so each part is understandable and testable. A complete, ready-to-run index.html is provided at the end. What we’ll build A small client-side app that: Takes ticket text. Calls text_sentiment […]
Managing a large volume of images can be a daunting task for individuals and businesses. You may run an eCommerce store, organize content for a media platform, or manage digital assets for a business. Keeping your images organized and easily discoverable is essential. Scalable image tagging is designed to efficiently handle large datasets while maintaining […]
Artificial Intelligence (AI) is transforming the way we utilize technology. Object detection APIs play a key role in this shift. The multi-object recognition API can detect multiple objects in a single image. This helps machines interpret visual information accurately. Industries such as retail, healthcare, and transportation are utilizing these APIs. They enhance productivity and facilitate […]
Speed is one of the most important factors on your website. If your web app loads slowly, users might leave before they even experience your product. According to Google research, 53% of mobile visitors abandon a page if it takes longer than three seconds to load. One of the biggest factors behind loading speed is […]
Visual content serves as a functional element, identity marker, and user experience component in modern applications. Users expect applications to deliver fast and seamless visual interactions when they use social platforms, e-commerce storefronts, or creative tools. An image hosting API functions as a file upload and image management platform, cloud storage, and maintains media organization. […]
You shouldn’t have to log into a dashboard to create a new app, rotate an API key, or check your usage. Manually managing infrastructure is a tedious distraction from building your actual product. The Filestack Management API lets you script every part of your file infrastructure, so you can stop clicking and get back to […]
As developers, we often face the challenge of extracting structured data from unstructured documents. Whether it’s parsing invoices, digitizing old records, or processing forms, the task can be tedious and error-prone. This is where OCR automation comes in—also referred to as automated OCR data extraction—offering a programmatic way to solve this common challenge. Introduction Optical […]
