About JPG/JPEG to WebP
JPG compresses photos with lossy quantization and no alpha channel, so files stay small while transparency is dropped. WebP re-encodes the same photo with a more recent codec, keeping similar detail at fewer bytes. There is no transparency to preserve, so flatten the source onto a background before converting. Stills carry no frames, so animation settings do not apply. Set the quality slider near 80 to 90 and match the source dimensions, then keep the JPG original in case you need another export.
Why convert JPG/JPEG to WebP?
- Flexible size with WebP lossless or lossy compression - lossy for smaller files, lossless for exact quality.
- Keep animation and transparency where supported.
- Private, no upload - runs in your browser.
JPG/JPEG vs WebP
| Animation | No | Yes |
|---|---|---|
| Transparency | No | Yes |
| Compression | lossy | lossless or lossy |
| Typical use | JPG is the same JPEG codec under the three-letter extension from DOS-era naming. | WebP stores still and animated images with better compression. |
When not to convert JPG/JPEG to WebP
- Skip WebP for archival masters: lossy compression discards detail, so keep the JPG/JPEG original.
- No motion to preserve: JPG/JPEG is a still, so pick WebP for size or compatibility rather than animation.
Limits
Starting point: JPG/JPEG - Small lossy photos for web pages and sharing. No transparency support, so alpha channels are dropped. Use the quality slider to balance size and fidelity. Set the quality slider near 80-90 for WebP photos from JPG/JPEG, and keep dimensions matched to the source.
