Frequently asked questions
How do I convert JPG to WebP?
Drop your JPG files onto the converter, click Convert, and download the WebP results. It all runs in your browser.
Is converting JPG to WebP lossless?
WebP is lossy, so a small quality change is possible; at 90% or above it is rarely noticeable.
Can I convert many files at once?
Yes. Add as many as your device's memory allows; they are processed in parallel by background workers and can be downloaded as a ZIP.
Are my images uploaded to a server?
No. Files are decoded, processed and re-encoded by your browser using the canvas API and Web Workers. Nothing is sent to any server, and there is no account or storage. Closing the tab discards everything.
