Converting PNG to WebP
This page is the PNG to WebP setting of our converter, with WebP already chosen. Drop a PNG file in and the result comes back as WebP — no account, no queue, and no watermark on the output.
The conversion runs entirely inside your browser tab. Your file is read into memory on your own machine, converted there, and handed straight back. Nothing is uploaded, which means there is no size limit imposed by someone else's bandwidth and no copy of your file sitting on a server after you close the tab.
What is PNG?
Lossless and transparency-capable. The right answer for screenshots, logos, diagrams and anything with flat colour and hard edges.
What is WebP?
Google's web format. Roughly 25–35% smaller than an equivalent JPG, supports transparency, and is read by every current browser — but plenty of desktop software still cannot open one.
What changes in this conversion
WebP is lossy, so this conversion discards some detail permanently. The quality slider controls how much.
Is it really free?
Yes, and there is no catch to explain. Because the work happens on your device rather than on a server, running this costs us nothing per conversion — so there is no bill to recover and nothing to gate behind a sign-up, a daily quota or a watermark.
