9 Efficient Strategies to Optimize Image Upload Time on Mobile Web Apps
"Optimizing image upload time on a mobile web app can enhance your user experience greatly. Here are the steps you can follow:
-
Image Compression: Before uploading images, compress them. Reduce file sizes without sacrificing quality. There are many libraries/tools available for almost every major programming language to compress images before uploading.
-
Image Resize: Resize the images before you upload it. Don't let the users upload a heavy high-resolution photo if it's going to be displayed in a smaller size on your app.
-
Use CDN (Content Delivery Network): CDNs can guarantee fast image upload and delivery. Images are stored on several servers distributed in different geographical locations, which allows faster access to content to users who are not near your server's position.
-
Correct Image Format: Use the correct image format. For example, vector images should be in SVG, icons and other graphics with limited colors should be in PNG, and photographs and other images should be in JPEG.
-
Lazy Loading: Incorporate "lazy loading," in which images only load when they come into the viewport. This technique saves bandwidth and speeds up page load time.
-
Browser Caching: When a user visits your site, the downloaded resources are stored on their local storage which means they do not need to be downloaded every time the page loads, reducing the number of calls made to your server.
-
Parallel Image Upload: When multiple images are being uploaded, do it in parallel rather than sequentially. This will speed up the overall upload time.
-
Avoid Base64: Always use binary formats to upload images, avoid using base64 as it increases the file size.
-
Background Upload: If possible, upload images in the background without interfering with the user’s interaction with the app.
Remember, these methods can be used in combination. Experiment with them to find a solution that works best for you and your users."
