WebP to JPEG
WebP does both transparency and lossy compression — only the second survives the move: empty areas become a solid colour of your choosing. In exchange the file gets markedly lighter. On our corpus a 1200×800 frame in JPEG averages 113 kB for a photograph and 9 kB for flat graphics — 100% of what JPEG takes at the same quality.
How to do it
- Pick a WebP file, drag it in, or paste with Ctrl+V
- The format is already set to JPEG — adjust the quality if you like
- Take the finished file. Several at once works too — you get a ZIP
Frequently asked questions
- How much smaller will the file be?
- On our corpus a 1200×800 frame in JPEG averages 113 kB for a photograph and 9 kB for flat graphics — 100% of what JPEG takes at the same quality.
- How visible is the loss?
- On flat graphics at quality 80, JPEG reaches a peak channel deviation of 56 with 0.07% of pixels visibly off. On a photograph that is imperceptible; on a diagram or screenshot with hard edges it shows, and PNG is the safer choice there.
- What happens to transparency?
- JPEG has no alpha channel — transparent areas become a solid colour. If you need transparency, pick PNG, WebP or AVIF; all three carry it. The fill colour is yours to choose in the widget.
- Will JPEG open everywhere?
- Yes. JPEG opens anywhere, from a browser to a printer.
- Will the coordinates and camera data survive?
- No. The image is redrawn from pixels and the metadata stays behind in the input file. The panel under the result shows exactly what was in there.
