IMAGE to WEBP Optimization FAQ

Will WebP actually be smaller than Image?

Almost always when going from PNG / JPG / TIFF into WebP or AVIF: expect 25-50% smaller than JPG at the same visual quality, 60-90% smaller than PNG. Going the other way (WebP / AVIF back to WebP = PNG / JPG) typically grows the file because you are leaving a more modern codec for an older one — useful for compatibility, not size.

Does Image to WebP preserve transparency / alpha?

Transparency survives when WebP supports alpha (PNG, WebP, AVIF, GIF, TIFF, SVG). Converting to JPG flattens the alpha channel onto white — if you need transparency on the modern web target WebP or AVIF instead of WebP.

Will the WebP version look identical to the Image on a Retina display?

At quality 80+ on WebP / AVIF the difference is invisible to anyone but a trained eye even at 3x device pixel ratio. Photos compress slightly more visibly than line art; if your Image is screenshots or UI mockups, push quality to 90 or use a lossless WebP.

Will EXIF camera metadata survive Image to WebP?

Usually not. In most conversions, camera EXIF fields such as the camera model and GPS position are not carried into the WebP. There is no setting on this page to keep or remove metadata, so check the result with a metadata viewer if it matters.

Can I batch convert a folder of Image files to WebP?

Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.

Are my Image files private during WebP conversion?

Yes. Uploaded Image files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted WebP are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.

How do I serve the WebP with an Image fallback on my site?

Use a `<picture>` element: `<picture><source srcset="image.WebP" type="image/WebP"><img src="image.Image" alt=""></picture>`. Browsers that understand WebP fetch the smaller file; older browsers fall back to Image. WebP is supported in 96%+ of installed browsers, AVIF in 90%+.

Why is my WebP file unexpectedly bigger / smaller than I expected?

An Image that is already heavily compressed (low-quality JPG) often grows when re-encoded into a lossless WebP (PNG / TIFF). A high-bitrate lossless Image (PNG / TIFF) often shrinks 60-90% when going to a lossy modern WebP (WebP / AVIF). Image content matters too — photos compress very differently from line art and screenshots.

IMAGE

Image files, such as JPG, PNG, and GIF, store visual information. These files can contain photographs, graphics, or illustrations. Images are used in a variety of applications, including web design, digital media, and file illustrations, to convey visual content.
