Before you start
Convert static JPEG or PNG images into real WebP files. PNG transparency is retained where supported; quality is a lossy encoder setting, not a promised size target.
How to use this tool
- Choose up to 20 saved PNG or JPG files. The originals stay on your device.
- Set WebP quality, then choose “Convert to WebP”.
- Check transparency, detail and file size. Download one WebP or the ZIP when converting several files.
Supported inputs and limits
Static JPEG or PNG only: up to 20 files, 20 MiB and 16 million pixels per image, 80 MiB per batch. Animated PNG is not supported.

}When something does not work
Use a supported, non-animated image within the stated pixel budget. Inspect transparent areas and orientation after export; reduce dimensions when the decoded image is too large.
Frequently asked questions
Are my files uploaded?
No. Files and tool input are processed in your browser. Moving around the site can keep a temporary workspace in the same tab. Refreshing or closing the tab clears it, so download results you want to keep.
What should I check in this result?
Check transparency, detail, dimensions and file size. PNG transparency should remain, but lossy WebP can change pixels and may be larger than the source.
