PNG to WebP converter.

WebP gives JPEG-class compression with PNG-class transparency. The same image is usually a quarter to a third smaller than its PNG, and every current browser (Chrome, Firefox, Safari 14 and later, Edge) decodes it.

Yes, fully: an 8-bit alpha channel like PNG's, not the 1-bit kind GIF has. Keep transparency is on by default; turn it off to flatten the image onto a color of your choice.

Everywhere that matters now. Older software, some email clients and a few image viewers still don't open it; serve a PNG or JPEG fallback through the picture element where those matter.

Any image the browser can decode: PNG, JPG, WebP, GIF, AVIF, BMP, ICO and SVG, up to 100 MB. The tool is named for PNG because that is where people arrive from, but the input doesn't have to be one.

80 to 90 for photographs, 70 to 80 for web graphics. The browser's encoder is lossy at every setting, so for a file that must be pixel-identical keep the PNG. Read the result's size as you move the slider.

Turn off Keep transparency and a background swatch appears. Pick the color, and transparent pixels are filled with it before encoding; the file gets a little smaller without the alpha channel.

No. The file is read in your browser and every step runs there, on your device. The page makes no request with your image, so you can load it, go offline and keep working.

No. The PNG to WebP converter is free and opens without a sign-in, an account or an install.

Up to 100 MB per file, the limit the tool states under its drop area. A larger file is refused with a plain message instead of being decoded.

No, it takes one file at a time. If you drop or choose several, only the first is used; run the tool again for the next one.

No. The browser decodes the image and the tool writes a new file from its pixels, so camera EXIF, GPS position and text chunks in the original are not copied into the result. Keep the original file if you need them.

It draws the image on a canvas and asks your browser to encode WebP. If your browser can't, the tool says 'This browser can't write WebP.' instead of saving a wrong file.

No. The result has the same width and height in pixels as the source.
