Why convert JPG to WebP?

  • About JPG: JPG (JPEG) uses lossy compression and produces small files, making it the default for photos and web banners — but it has no transparency.
  • About WebP: WebP is a modern Google format that is ~25-35% smaller than JPG/PNG at the same quality and supports both transparency and animation.

Converting from JPG to WebP is most useful when you need WebP's strengths — for example wider app compatibility, smaller files, or the right balance of quality and size.

How to convert JPG to WebP

  1. Open the WebP converter below and drop in your JPG file.
  2. The image is decoded and re-encoded to WebP locally in your browser — it is never uploaded.
  3. Preview the result, then download your new WebP file.

Tips for the best result

  • For photos, keep quality around 80% to balance sharpness and file size.
  • If your JPG has transparency and WebP does not support it, transparent areas are flattened onto a white background.
  • Need a smaller file afterwards? Run the output through the compressor.
