How to convert PNG to WebP
Three steps to lighter images — no uploads.
Add your WebP files
Drag and drop, or click to browse. Up to 50 images at once.
Convert to WebP
One click — every PNG becomes a much smaller WebP, transparency preserved.
Download
Grab your WebP files one by one, or all at once as a ZIP.
Same picture, smaller file
WebP typically weighs 25–35% less than PNG at visually identical quality — faster pages, lighter emails.
Private by design
Every operation runs inside your browser. Your images are never uploaded anywhere.
Free & unlimited
No accounts, no daily caps, no watermarks stamped on your files. Ever.
Transparency survives
Transparent PNGs stay transparent as WebP — no white boxes where your logo used to be.

Frequently asked questions
Does converting PNG to WebP lose quality?
WebP encoding is very efficient — for typical graphics the result looks identical to the original PNG while the file gets much smaller. Transparency is fully preserved.
Do all browsers support WebP?
All major browsers have supported WebP for several years now. If you need to reach very old systems, converting to JPG is the safer choice.
Are my images uploaded to a server?
No. The conversion runs entirely in your browser — your images never leave your device.
Is there a limit?
Up to 50 images per batch, each up to 30 MB.
