WebP Converter

Convert images to WebP — and WebP back to PNG or JPG.

The WebP Converter moves images between WebP, PNG and JPEG in either direction. Convert JPG or PNG photos to WebP for dramatically smaller web files, or convert WebP back to PNG or JPG when a system does not accept the format.

WebP is Google's modern image format: typically 25–35% smaller than JPEG at the same quality and smaller than PNG for most graphics, with transparency support and wide browser compatibility. Converting a site's images to WebP is one of the highest-impact performance wins available — this tool makes the conversion instant and private.

The converter runs entirely in your browser with a quality slider for lossy output, shows before/after sizes, and keeps your originals untouched. WebP export needs a recent browser (all modern ones support it).

Choose an image (PNG, JPG or WebP). Conversion runs locally in your browser — no upload.

How to use the WebP Converter

  1. Choose an image — JPG, PNG or an existing WebP.
  2. Pick the target format: WebP, PNG or JPEG.
  3. Adjust quality if converting to WebP or JPEG.
  4. Click 'Convert'.
  5. Download the result.

Frequently asked questions

Why should I convert images to WebP?

WebP compresses better than JPEG and PNG in most cases — roughly 25–35% smaller than JPEG at equal quality and often smaller than PNG for graphics — which makes pages load faster and saves bandwidth. All modern browsers display it natively.

Can I convert WebP back to PNG or JPG?

Yes — choose PNG or JPEG as the output format. Converting to PNG preserves what losslessness is possible; converting to JPG produces the classic format for older systems that do not accept WebP.

Is WebP supported everywhere?

WebP is supported in every modern browser (Chrome, Edge, Firefox, Safari since 14) and in major image editors. Older niche tools may not open it — convert back to PNG/JPG for those cases.
