Getting the best page-speed gains
Converting format is only half the job: a 6000-pixel camera photo displayed 800 pixels wide wastes most of its bytes. Resize photos to roughly twice their display width with the Image Resizer before converting, and check your page's actual image sizes with the Image Dimension Checker. Re-encoding an already compressed JPG adds a second round of loss, so convert from the highest-quality original you have.
Benefits
- WebP photos are typically 25–35% smaller than JPGs of similar quality.
- Quality slider and per-file savings report.
- Batch conversion with ZIP download, entirely offline once the page is loaded.
Limitations
- Re-encoding a JPG is lossy, so start from the best original you have.
- EXIF data such as camera details and GPS location is not copied to the WebP file.
Privacy and security
Images are decoded and re-encoded by your browser in a background Web Worker (or on the page itself in browsers without OffscreenCanvas). Files are never uploaded, and the results exist only in this tab's memory until you download them.

Frequently asked questions
Does WebP look worse than JPG?
At the same file size WebP usually looks better, and at the same visual quality it's smaller. Compare the original and the result with the Compare button before replacing your files.
What quality is equivalent to my JPG?
WebP at 75–85% generally matches a JPG saved at 85–90%. Lower values save more but can soften fine textures.
Can every browser show WebP?
Yes, all current browsers do. If you must support very old Safari versions, serve WebP with a JPG fallback using the HTML <picture> element.
