Convert JPG to WebP

Convert JPG and PNG to WebP for faster websites, with a quality slider.

Drop a file here or click to browse

Accepts JPG, JPEG, PNG. Up to 50.0 MB per file.

WebP is supported by every current browser and by most CMS platforms, and it produces files 25-35% smaller than JPG at equal quality. Smaller images mean faster Largest Contentful Paint, which matters for both users and search ranking. Converting your existing JPG and PNG assets is the quickest win.

This tool uses the browser's own WebP encoder. PNG sources keep their transparency, since WebP supports an alpha channel. Metadata is not carried over, which is normally what you want for web assets.

How to use it

  1. Drop a JPG or PNG file, or click to browse.
  2. Choose a quality. 80-85% is the usual sweet spot for photos; use 90%+ for images with fine text.
  3. Click Convert.
  4. Download the .webp file and compare the size shown against the original.

Frequently asked questions

Is WebP safe to use on my website?

Yes. Chrome, Firefox, Edge, Safari (since 14) and all major mobile browsers support it. Keep a JPG fallback only if you must support very old browsers.

Does WebP keep transparency from PNG?

Yes. Lossy WebP with alpha is supported and is usually far smaller than the PNG.

Why not AVIF?

AVIF is smaller still, but browser encoders for AVIF are not widely available in the canvas API yet. WebP is the practical choice for in-browser conversion today.
