How to use this tool

  1. Add images. Choose JPG, JPEG or PNG files, up to 20 in a batch and 20 MB each. Transparent PNGs are welcome.
  2. Pick a quality. Leave the slider at 90 for a version that is hard to tell from the original, or lower it to squeeze out more savings.
  3. Convert. Each picture is drawn to a canvas at its full size and encoded by your browser's WebP encoder.
  4. Compare sizes. The list shows the original size and the new WebP size for every file, so you can see exactly what the change bought you.
  5. Download. Grab files one by one or press Download all (ZIP) to save the batch together.

Why use this tool

WebP usually beats JPG and PNG at the same visual quality, often by a quarter or more. On a page with a dozen product photos that difference is measured in seconds of loading time and in mobile data. This tool lets you test the format on your own images before committing to it in a build pipeline.

Quality is worth checking image by image: a sharp graphic with flat colour can take a lower setting than a portrait with delicate skin tones. Because the list keeps every output separate, you can compare a few settings and keep the version that looks right. Nothing is uploaded, so client work and personal albums stay on your computer. The tool also refuses to hand you a PNG with a .webp name: if the browser cannot encode WebP, you get an explicit error instead of a mislabelled file.

Frequently asked questions

What is WebP and why use it?
WebP is an image format made for the web. At similar visual quality it is usually smaller than JPG or PNG, which makes pages load faster and uses less bandwidth. Every current major browser can display WebP images.
Why does the tool say my browser cannot create WebP?
Encoding WebP in the browser depends on the Canvas API. Older browsers fall back to PNG without warning, so this tool checks the output type and stops with a clear message instead of saving the wrong format. Updating to a recent Chrome, Edge, Firefox or Safari usually fixes it.
Does transparency survive the conversion?
Yes. A transparent PNG stays transparent in WebP because WebP supports an alpha channel. Use the PNG to JPG tool instead if you need a white background rather than transparency.
Can I convert the WebP back later?
Yes. The WebP to JPG tool opens WebP files and saves them as JPG, which is handy for apps that still do not read WebP. Keep the original if you expect to need other formats in the future.
