While slow network connection isn’t directly the app’s performance issue, it may cause the users to abandon the upload process or leave the app. However, developers can implement various techniques to mitigate this issue and enhance the user experience. For example, you can compress file size, implement resumable uploads, etc. We’ll discuss these techniques in detail later in the article.

Handling large files

Today’s modern smartphones enable users to capture high-resolution images, leading to large image file sizes. When users upload such image files on your Android app, it can significantly impact the image upload speed. That’s because large files consume lots of bandwidth and storage space. Large image files can also overload server resources, leading to slow loading times.

Fortunately, techniques like file compression, chunk and parallel uploads can help with the efficient handling of large files.


With the ever-increasing cyberattacks, the security of image file uploads is a serious concern. Image files may contain sensitive information, such as location data and personally identifiable information (PII). Cybercriminals today exhaust all techniques to gain access to sensitive data and misuse it. Moreover, attackers may attempt to upload malicious image files such as executable files or scripts. These files can compromise the server or other users’ devices.

Therefore, developers must ensure secure file uploads by implementing techniques like file type validation, anti-virus scanning, etc.

Delivering an exceptional user experience

While quick image upload enhances the user experience, users today also want additional features. These include:

  • Progress bars
  • Image preview
  • Drag-and-drop interface
  • Multiple image uploads, and more.

Creating all these features from scratch can be time-consuming and challenging for Android developers. Fortunately, various quick third-party image upload solutions for Android apps are available today. Developers can use these solutions to integrate image upload functionality into their apps quickly. Moreover, these solutions often provide advanced image upload features like image preview and progress bars.

Battery consumption

Image uploads can consume a significant amount of mobile devices’ battery power. This is especially true when the upload process takes a long time due to a weak internet connection or other issues. Reduced battery life leads to users’ dissatisfaction with the app’s performance.

Exploring quick image upload solutions and techniques

 Quick Image Uploads

Here are some techniques to ensure quick image upload in your Android apps:

Image compression and optimization

Resizing and compressing images before uploading them helps reduce file size, leading to fast uploads. However, it’s crucial to strike the right balance between image size and quality. You can use tools like Picasso or Fresco to compress files. If you’re using an image upload solution like Filestack, you can compress files directly. For example, Filestack allows you to compress your files with a simple API request through its processing API.

Moreover, it’s recommended to use modern image formats like WebP. WebP provides better compression compared to traditional formats like JPEG or PNG. If a user uploads an image file in another format, such as PNG, you can convert it to WebP before uploading. Filestack supports file type conversion via its processing API. It supports various image formats, including WebP, JPG, and PNG.

Chunk and resumable uploads

Chunk uploads involved breaking an image file into various pieces or chunks and uploading each chuck one by one sequentially. This technique is especially helpful for large image files. Moreover, you can also implement resumable uploads to enable users to resume uploading from where they left off in case of network interruptions or failed uploads. These techniques help minimize the impact of slow connections and reduce the likelihood of failed uploads.

You can create custom chunked upload logic or use libraries like OkHttp’s MultipartBody. Filestack also supports chuck and resumable uploads to ensure fast image upload.

Progressive image loading

You can display low-resolution versions of images while high-resolution versions are being uploaded. This provides users with immediate visual feedback and minimizes the impact of slow uploads. Thus enhancing the user experience. If you’re creating image upload functionality from scratch, you can use libraries like Glide for progressive image loading.

You can also implement progressive loading with Filestack. When you upload an image to Filestack, you can configure various processing options, including progressive rendering. By enabling progressive rendering in Filestack, you can ensure that images are delivered to users in a progressive manner, enhancing the perceived performance.

Cloud storage and CDN (content delivery network)

Leveraging cloud storage or a free image hosting service to store user-uploaded files can significantly boost your app’s performance. Cloud storage solutions allow you to store a large number of image files without worrying about storage space. Moreover, utilizing a CDN will enable you to deliver uploaded content/ images to users worldwide.

A CDN is essentially a network of servers and data centres distributed around the globe. It caches your app content, such as images, and stores their copies in its global servers. Then, when a user requests an asset/image, the CDN delivers it from the server nearest to the user. This reduces latency and helps deliver images online quickly.

Filestack saves all uploaded images in an S3 bucket. It also allows you to integrate your own cloud storage solution with the uploader and store images there. Moreover, with Filestack, you automatically deliver images through a powerful CDN. Once a user uploads an image through Filestack File Picker/Uploader, Filestack instantly returns a CDN URL. You can use this CDN URL to deliver images to your users quickly and seamlessly.

Network quality detection

Implement techniques to detect the user’s network quality and adjust upload strategies accordingly. For example, you can throttle upload speeds on slower connections. Additionally, you can prioritize uploads based on network conditions. For example, you can upload smaller images first.

If you’re using Filestack, you can rely on it to automatically adjust to different network conditions. Filestack leverages Intelligent Ingestion™ that efficiently adjusts to changing network conditions to guarantee upload success 99.999% of the time.

Drag-and-drop interface
