WebP

WebP is an image format designed for the web that compresses photos and graphics more efficiently than JPG or PNG. It supports both lossy and lossless compression and transparency, so a WebP file is usually smaller than the equivalent JPG or PNG while looking the same. Almost every modern browser supports it.

Why WebP matters

Images are usually the heaviest part of a web page, and heavy pages load slowly. WebP was built to fix that by shrinking images without a visible quality drop, which is why so many sites now serve it. Smaller images mean faster pages and lower data use for visitors.

The catch is the same one every newer format faces. A file that a browser opens instantly might be rejected by an older program or an upload form that only knows JPG and PNG. Compatibility is the reason conversions still happen in both directions.

How to convert to or from WebP

  1. Open the image converter.
  2. Drop in the file you want to change.
  3. Pick WebP for a smaller web image, or JPG and PNG for wider compatibility, and download.

Every conversion runs on your device, so your images are never uploaded to be processed.

Frequently asked questions

Is WebP better than JPG and PNG?

For file size at similar quality, yes. WebP typically produces smaller files than JPG for photos and smaller than PNG for graphics with transparency. JPG and PNG still win on compatibility with older or offline software.

Do all browsers support WebP?

Every current major browser supports WebP. The gaps are older software, some desktop image viewers, and a few upload forms, which is why converting to JPG or PNG is sometimes still necessary.

How do I open or convert a WebP file?

Browsers open WebP directly. To use one in software that rejects it, convert it to JPG or PNG. FileGizmo does this in your browser without uploading the image.
