How to convert JFIF to WebP
- Drop your JFIF files on the box above, or click it to choose them (up to 30 at once).
- Check the settings — the quality slider trades file size against detail.
- Press Convert. Each file is processed on your device and shows its old and new size.
- Download the files one by one or take them all as a ZIP.
What changes when you convert JFIF to WebP
- The image is decoded and compressed again as WebP at the quality you choose. A small loss of detail is part of lossy compression; at the default 92% it is very hard to see.
- JFIF images have no transparency, so there is nothing to lose there.
- Camera details and GPS location (EXIF) are not copied into the new file. Photo orientation is applied to the pixels first, so the result is the right way up.
About JFIF and WebP files
A .jfif file is an ordinary JPEG with a different extension — Windows and some browsers save JPEG images that way. Inside, the data is the same as a .jpg.
WebP is Google’s web image format. At the same visual quality it is usually smaller than JPEG and PNG, and it supports transparency, but older desktop software may not open it. It is a good choice for images for websites, where smaller files load faster.
Limits
Up to 30 files of 25 MB each per batch and images up to 50 megapixels — beyond that browsers run out of memory, so the tool says so instead of producing a broken file. Writing WebP needs Chrome, Edge or Firefox; older Safari versions cannot, and the tool tells you rather than saving a PNG under a .webp name. Files that are not images, or are damaged, are rejected with the reason.
