Frequently asked questions

Is WebP Compressor free to use?

Yes. WebP Compressor is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.

Does WebP Compressor upload your image to a server?

No. WebP Compressor processes your image inside your browser, so it never reaches a DocTools server. That also means the tool keeps working if your connection drops mid-task.

Is there a file size limit?

The practical ceiling is your device's available memory rather than a server quota. Files up to roughly 100 MB work comfortably on a typical laptop in WebP Compressor.

Do I need to install anything to use WebP Compressor?

No installation is needed. WebP Compressor runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.

Can I use WebP Compressor on a phone or tablet?

Yes. The WebP Compressor interface adapts to small screens and supports touch input, though very large jobs are faster on a desktop browser.

What happens to your image when I close the tab?

It is discarded. WebP Compressor keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
