Lastly, we’ll guide you through integrating Filestack into your app and show you the results you can achieve. We’ll wrap up with some common questions. Let’s get started!

What do you mean by image enhancement?

Image enhancement means improving the quality of an image to make it look better. This process involves several techniques to make images clearer, brighter, and more appealing.

For example

👉If a photo is too dark, you can increase the brightness to make it more visible. 

👉Adjusting the contrast can make the details in the image stand out. 

👉Sharpening is another method that makes the edges and details in the photo more defined.

👉Noise reduction helps remove any grainy spots in a picture, making it look smoother. 

👉Filters can change the color of an image. For instance, a sepia filter can give a photo an old-fashioned look, while a black-and-white filter can create a classic style.

Image enhancement is important in many applications. In online shopping, better images can help sell more products. On social media, enhanced photos can get more likes and shares. Photo editing apps use these techniques to let users create beautiful pictures.

Using image enhancement, developers can ensure that their apps show images in the best possible way, creating a better user experience.


Image enhancement improves the quality of pictures in many areas. One major use is on social media, where people enhance their photos to get more likes and shares. They use filters, adjust brightness, and change colors to make their images look better.

Good product photos are very important in online shopping. Enhanced images show details, colors, and textures more clearly, helping customers make better buying decisions and increasing sales. Clear and attractive product photos can also reduce the number of returns.

Photo editing apps also use image enhancement. These apps let users improve their photos by making them sharper, brighter, and more colorful. Both amateur and professional photographers use these tools to create beautiful pictures.

Image enhancement is crucial in healthcare. Doctors use it to make medical images like MRIs and X-rays clearer, which helps them diagnose and treat patients more accurately.

Image enhancement also benefits security and surveillance. Enhanced images from cameras help identify people and objects more easily, which is important for investigations and monitoring.

What are the popular methods to integrate image enhancement features within your apps?


Filestack Image Enhancement automatically analyzes an image and applies color corrections to improve its quality. You can also make other adjustments to enhance the image further. To achieve the best results, you can choose from various presets. 

Note that images must be under 10MB to use enhancement features. Filestack Image Enhancement is a premium feature. Contact our support team to add it to your plan.

Integration with Filestack

The first step towards a successful integration is to get your API key. For this purpose, you create an account at Filestack and get the API key shown on the dashboard. 

The next step is to open the Filestack documentation for image enhancement endpoints. You must test these endpoints with your API key using an API testing tool. Postman is one of the most popular API testing tools. Let’s test our API via Postman. 

Here are the image enhancement URLs by Filestack: 

This task automatically enhances images using the handle of the uploaded file. Here are the presets available at Filestack for image enhancement with their purpose:

Preset Description
auto Automatically selects the best enhancement settings for a photo.
vivid Enhances depth and brightness in a photo.
beautify Ideal for portraits, this preset scans each face in the photo and adjusts corrections individually for optimal results.
beautify_plus Similar to Beautify, it applies stronger corrections with a broader range of modifications.
fix_dark It is perfect for underexposed photos or dark subjects against bright backgrounds. Turning off contrast maximizes detail in shadow areas without blowing out highlights.
fix_noise Detects and removes noise from photos while preserving details. Adjusts based on the ISO level and camera model.
fix_tint Removes abnormal tints (yellow, blue, green, etc.) caused by various lighting conditions, such as fluorescent, infrared, ultraviolet, and tungsten lights.
outdoor Enhances landscape photos by increasing colour vibrancy and adjusting the contrast to reveal more detail in shadow areas.
fireworks Corrects for night skies and highlights excess colours from fireworks.

Here is an example of how you can use these presets: 

Here is another example that chains other tasks with the preset: 

Open the Postman and create a new GET request as under:

Postman GET request

Next, add the URL to the GET request bar: 

Add your API key and replace HANDLE with the URL to your desired image.

Let’s create our application and integrate the Filestack image enhancement features. 

Building the sample application

Create an index.html file in your project directory on the command prompt. 

Open that file inside the Visual Studio Code. 

Add the below code to that file:

HTML Structure
<!DOCTYPE html>

<html lang="en">


    <meta charset="UTF-8">

    <meta name="viewport" content="width=device-width, initial-scale=1.0">

    <title>Filestack Upload and Enhance</title>

    <script src=""></script>


        /* Styles will be explained later */




    <div class="container">

        <!-👉Content will be explained later -->



        /* JavaScript will be explained later */




👉The `<!DOCTYPE html>` declaration defines the document as HTML5.

👉The `<html lang=”en”>` tag sets the language of the document to English.

👉The `<head>` section contains meta information, including character encoding, viewport settings for responsive design, the page title, and the Filestack JavaScript library.

👉The `<body>` contains the main content of the page.

CSS for Styling

You can access the CSS styles through the GitHub repository:

👉The `body` styles center the content, set a background image, and apply a general style.

👉`.container` styles create a centered, white box with padding, rounded corners, and a shadow.

👉`h1` styles set the heading’s font size and color.

👉`button`, `select`, `input` styles define the look and feel of interactive elements.

👉`.enhance-buttons`, `.options-container` styles initially hide certain elements.

HTML Content
<div class="container">

    <h1>Enhance Your Images with Filestack</h1>

    <button id="uploadBtn">Upload File</button>

    <div class="enhance-buttons">

        <button id="autoEnhanceBtn">Enhance with AI</button>

        <button id="manualEnhanceBtn">Set Your Own Enhancements</button>


    <div class="options-container">

        <select id="presetSelect">

            <option value="auto">Auto</option>

            <option value="vivid">Vivid</option>

            <option value="beautify">Beautify</option>

            <option value="beautify_plus">Beautify Plus</option>

            <option value="fix_dark">Fix Dark</option>

            <option value="fix_noise">Fix Noise</option>

            <option value="fix_tint">Fix Tint</option>

            <option value="outdoor">Outdoor</option>

            <option value="fireworks">Fireworks</option>


        <input type="number" id="resizeWidth" placeholder="Width (px)">

        <input type="number" id="resizeHeight" placeholder="Height (px)">

        <button id="applyEnhancementsBtn">Apply Enhancements</button>



👉`h1` displays the main heading.

👉`button id=”uploadBtn”` is for uploading files.

👉`div class=”enhance-buttons”` contains buttons for automatic and manual enhancements.

👉`div class=”options-container”` contains options for manual enhancements.

JavaScript Functionality

    // Initialize Filestack client

    const filestackClient = filestack.init('YOUR_API_KEY');

    const uploadBtn = document.getElementById('uploadBtn');

    const enhanceButtons = document.querySelector('.enhance-buttons');

    const optionsContainer = document.querySelector('.options-container');

    const presetSelect = document.getElementById('presetSelect');

    const resizeWidth = document.getElementById('resizeWidth');

    const applyEnhancementsBtn = document.getElementById('applyEnhancementsBtn');

    let uploadedFileHandle = '';

    // Upload file button click event

    uploadBtn.addEventListener('click', () => {


            onUploadDone: (result) => {

                if (result.filesUploaded.length > 0) {

                    uploadedFileHandle = result.filesUploaded[0].handle;

           = 'block';

                    console.log('File uploaded:', uploadedFileHandle);

                } else {

                    console.error('No files uploaded');





    // Auto Enhance button click event

    document.getElementById('autoEnhanceBtn').addEventListener('click', () => {

        const enhanceUrl = `${uploadedFileHandle}`;, '_blank');
