FAQ

Good to know.

How do I convert PNG to WebP?
To convert PNG to WebP, drop your .png files onto the Pixasur converter and it re-encodes each one to .webp in your browser, then you download them. The conversion is client-side, so nothing is uploaded to a server.
Does WebP keep the transparency from my PNG?
Yes, converting PNG to WebP keeps transparency, because WebP supports an alpha channel just like PNG. This makes WebP a good replacement for PNG on the web where you need both transparency and smaller files.
Is WebP smaller than PNG?
Yes, WebP is usually much smaller than PNG, often 25 to 50 percent smaller for graphics and far smaller for photos, while keeping transparency. That size saving is the main reason to convert PNG to WebP for websites.
Is the PNG to WebP converter free?
Yes, the Pixasur PNG to WebP converter is completely free with no sign-up and no watermark, and there is no limit on the number of files. Batch conversion and zip download are included.
Does the PNG to WebP converter work on a phone?
Yes, the Pixasur PNG to WebP converter runs in any modern mobile browser on Android or iPhone, and your images stay on the device because the conversion happens in the browser. No app install is needed.
