Why convert PNG to WEBP?

WebP was made by Google for the web. A PNG screenshot, logo or illustration saved as WebP is usually 25 to 35 percent smaller at the same look, and WebP keeps transparency, so it can replace PNG almost everywhere on a website. Smaller images mean faster pages, which visitors notice and search engines reward.

When to keep the PNG

Keep the PNG as your master copy if you will edit the image again, and use PNG when you send files to print shops or older desktop software, which do not always open WebP.

Tips for the best result

Common problems and fixes

The WebP is not much smaller than the PNG.
PNGs that are already optimised and have few colours compress well on their own. Lower the Quality a little, or keep the PNG.
An old program will not open the WebP.
All current browsers support WebP, but some older image editors do not. Convert it back with WebP to PNG when you need to edit it there.

PNG – Portable Network Graphics

PNG stores images with lossless compression and supports full transparency, which makes it the usual choice for logos, screenshots and graphics with sharp edges. The trade-off is size: a photograph saved as PNG is normally far larger than the same photo saved as JPG or WebP.

WEBP – WebP

WebP is an image format developed by Google. It supports lossy and lossless compression, transparency and animation, and at comparable visual quality its files are usually smaller than JPG or PNG. That is why it is popular for websites, and current versions of all major browsers can display it.

Frequently asked questions

Does PNG to WebP keep transparency?

Yes. WebP supports an alpha channel, so transparent and semi-transparent pixels are kept exactly as in the PNG.

Is WebP lossless?

WebP can be lossless or lossy. This converter uses lossy WebP at the Quality you choose, which gives far smaller files; at Quality 90 and above the difference is very hard to see.

How do I convert PNG to WEBP?

Click Select File or drop your PNG file onto the upload box. Pick the quality and maximum size, and the converted WebP appears in the list below with a download button. You can add many files at once and download them together as a ZIP.

Is it really free?

Yes. There is no sign-up and no watermark. To keep the service available for everyone there is a 95MB limit per file and a cap on how many files one connection can process in a short period.

Are my files stored?

Your upload is used only to make the converted file. Images are processed in memory; other files are written to a private temporary folder that is deleted as soon as the conversion finishes. Nothing is kept after the result has been sent back.

Will quality drop?

For images, a little, by design: the image is re-encoded at the Quality you choose (default 75%). Audio and video are re-encoded with high-quality settings; documents keep their text and layout as far as the target format allows. Converting never restores detail that is already missing from the original.

How this works: your file is uploaded over HTTPS and converted on this server with open-source engines (libvips for images, FFmpeg for audio and video, LibreOffice and Pandoc for documents, Calibre for ebooks, Ghostscript and Inkscape for PDF and vector files). Images are processed in memory; other files use a private temporary folder that is deleted as soon as the conversion finishes.
