Questions

Is converting JPG to WEBP free?

Yes. Conversion runs in your browser on every plan, with no account, no watermark and batches of up to 200 files.

Are my JPG files uploaded?

No. The browser decodes each file and encodes the new one on your device. Nothing is sent to a server.

Does converting JPG to WEBP lose quality?

WEBP is lossy at the quality you pick. At 80 to 90 it looks the same as the source for photos and is much smaller.

Can I make the WEBP bigger at the same time?

Converting keeps the pixel size. To enlarge, run the upscaler afterwards: 2× is free and also runs on your device.
