FAQ

How much smaller is WebP than PNG?

Usually 60 to 85% smaller for photos. The exact saving depends on the image, but the quality stays the same to the eye.

Does transparency survive?

Yes. WebP supports the same alpha channel as PNG, so transparent areas are kept.

Is WebP lossy or lossless?

Both. This tool uses lossy WebP at a high quality for the smallest size, but WebP can do lossless too.

How do I convert PNG to WebP on Windows, Mac, or iPhone?

It works in any modern browser on Windows, Mac, and iPhone. Drop your PNG files and download the WebP versions. There is nothing to install.

Should I use WebP everywhere?

Almost. WebP is great for the web and modern apps. Keep a PNG copy if you need to open the file in older software that doesn't read WebP.

Are files uploaded?

No. The conversion runs in your browser. Your files only leave your device if you click 'Get URL' to host one.

Batch size limit?

No fixed limit. Drop a whole folder of PNGs and they convert one after another, right in your browser.

Does EXIF carry over?

No. Re-encoding to WebP drops the EXIF data, which also helps with privacy.

Want a hosted URL?
