Frequently asked questions
- Is this image to WebP converter free?
- Yes, it's 100% free with no account, no watermarks, and no usage limits. Convert as many images as you like.
- Are my images uploaded to a server?
- No. All conversion happens locally in your browser using the canvas API. Your images never leave your device, which keeps them completely private.
- What image formats can I convert to WebP?
- Any format your browser can decode, including PNG, JPG/JPEG, GIF, BMP, and even existing WebP files. The output is always a WebP file.
- What does the quality slider do?
- It controls WebP compression from 10% to 100%. Lower quality produces a smaller file with some visual loss; higher quality keeps more detail at a larger size. 80% is a good default for most photos.
- Why is WebP better than JPG or PNG?
- WebP typically produces significantly smaller files than JPG or PNG at similar visual quality, which speeds up page loads and saves bandwidth. It's supported by all modern browsers.
- Does WebP support transparency?
- Yes. WebP supports an alpha channel, so transparent areas from PNG images are preserved in the converted file.
