Frequently asked questions
Is this PNG to WebP converter really free?
Yes, entirely free, with no account, watermark, or file limit imposed by a server — because there is no server involved.
Does my image get uploaded anywhere?
No. The conversion happens locally in your browser tab using the Canvas API. Your file never leaves your device.
Why convert PNG to WebP?
WebP typically produces significantly smaller files than PNG while keeping transparency support, which helps pages load faster — most modern browsers support it natively.
Doing this by hand every week? That's exactly what I remove.
If this conversion is one small step in a bigger workflow — say, files arriving by email, getting converted, renamed and filed by a person every time — I build software that does the whole thing automatically. My clients get back up to 18 hours a week this way.
