Frequently Asked Questions

How does client-side processing work?

Client-side processing uses your browser's built-in capabilities (HTML5 Canvas API and JavaScript) to manipulate images directly on your device. This means faster processing, better privacy, and no dependency on server availability.

What browsers are supported?

ResizingImg works on all modern browsers including Chrome, Firefox, Safari, and Edge. We recommend using the latest version of your browser for the best performance and features.

Is there a file size limit?

There's no artificial file size limit imposed by our tool. However, very large files (over 50MB) may take longer to process depending on your device's capabilities and available memory.

Can I use this for commercial projects?

Yes! ResizingImg is completely free for both personal and commercial use. There are no licensing fees, watermarks, or usage restrictions.
