Convert Images to WebP
Convert JPG, PNG, HEIC, PSD and 70+ other formats to small WebP files for websites. Pick a quality or a file size, keep see-through areas. Free, no upload.
FormatsGuideNew in v1.0
Turn any image into a small WebP file for websites. You choose: smallest file, or every pixel exactly the same.
Convert to WebP#
- Choose WebP as the Output Format.
- Pick how to compress:
- Set by Quality (default): pick a quality. 80–85 looks great and keeps files small.
- Lossless WebP: turn this switch on to keep every pixel exactly the same ("lossless"). Files get bigger.
- Drop your images and click Start Converting.
- Download each file, or all of them as a ZIP.
Need a maximum file size?#
Switch to Set by File Size and enter a limit, e.g. 500 KB. ImgCompress finds the best quality that fits. This works when Lossless WebP is off. More in Target a specific file size.
Good to know#
- See-through areas are kept, with Lossless WebP on or off. Background removal works with WebP too.
- Colors stay right, for example in iPhone photos.
- Rotated phone photos come out the right way up.
- Size limit: WebP images can be at most 16383 px wide or high. Bigger images get a clear error message.
From the command line#
bashdocker run --rm \ -v "$(pwd):/container/images" \ -v "$(pwd)/done:/container/done" \ karimz1/imgcompress:latest \ cli /container/images /container/done \ --format webp --quality 82
Add --webp-lossless for lossless files.
