About WebP
WebP is an image format that supports lossy compression, lossless compression and transparency. WebP files are often smaller than JPG or PNG files of similar visual quality, which can help pages load faster. The saving depends on the image and the settings, and for some images the WebP file is larger, which is why this tool shows the real size of every result.
Current major browsers can display WebP images. Some older software and apps may not open them, so keep your original files.
Privacy and limits
- Images are processed in your browser. The tool does not send them to a server.
- Up to 20 files at a time, 25 MB per file, and about 40 megapixels per image.
- Converting re-encodes the image, which normally removes embedded metadata such as camera details, and may not keep colour profiles.
- Animated GIFs are converted as a single still frame.
- Whether a browser can create WebP files depends on the browser. If yours cannot, the tool tells you.
Frequently asked questions
Are my images uploaded?
No. The conversion runs in your browser using built-in image features. You can confirm this by watching the network tab of your browser's developer tools while you convert a file.
Why is a converted file sometimes larger?
Very small, already well-compressed or simple images can grow when re-encoded. The tool reports the difference whether the file got smaller or larger, so you can keep the original when that happens.
Does WebP keep transparency?
Yes, WebP supports transparency, so transparent areas of PNG images are kept.
Which quality should I choose?
It depends on the image. Try a few values and compare the preview and size. Photos usually tolerate more compression than screenshots or graphics with fine text.
