JPEG to WebP
On the same shot WebP comes out 1.3× lighter than JPEG: 85 kB against 113 kB on a 1200×800 frame. The work happens inside your tab — the image is never sent to a server.
How to do it
- Pick a JPEG file, drag it in, or paste with Ctrl+V
- The format is already set to WebP — 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 WebP averages 85 kB for a photograph and 3 kB for flat graphics — 75% of what JPEG takes at the same quality.
- How visible is the loss?
- On flat graphics at quality 80, WebP reaches a peak channel deviation of 69 with 0.41% 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.
- Will WebP open everywhere?
- Every current browser reads WebP. Older desktop viewers and some messengers still trip over it — if the file is going to a person rather than to the web, JPEG or PNG is safer.
- Why do phone photos sometimes come out sideways?
- Because the orientation lives in a separate EXIF tag rather than in the pixels, and most converters ignore it. Here the tag is read and applied before anything else, so a portrait shot stays portrait.
