WebP Converter
Convert JPG and PNG images to WebP, or WebP back to PNG. WebP typically produces files 25–35% smaller than JPG at the same visual quality and supports transparency, which JPG does not. The encode runs in your browser using the Canvas API — no upload.

Questions
- Is WebP supported everywhere?
- Yes, in every current browser — Chrome, Firefox, Safari, Edge — since 2020. The remaining caveat is older software outside the browser: some desktop image viewers and older versions of Office still will not open a WebP.
- How much smaller will my files be?
- Typically 25–35% smaller than an equivalent-quality JPG, and often far smaller than a PNG for photographic content. Flat graphics with few colours sometimes compress better as PNG, so it is worth checking both.
- Does WebP support transparency?
- Yes, with a full alpha channel, which is the main reason to prefer it over JPG for logos and product cut-outs. You get PNG's transparency at closer to JPG's file size.
