Drop in your PNG file, convert it to WebP right here in your browser, and download the result — no uploads, no sign-up, and no watermark.
How to use it
1. Drop your PNG image onto the drop zone or click to browse.
2. The tool converts it to WebP automatically — preview the result to confirm it looks right.
3. Download the WebP file. Everything is processed on your device.
What changes when you convert PNG to WebP
WebP is a modern web format that is typically 25–35% smaller than JPG at the same quality and still supports transparency. Transparency is preserved, since WebP also supports an alpha channel. WebP is lossy, so the image is re-encoded and cannot gain quality — pick a high quality setting to keep it looking the same.
Convert PNG to WebP when your destination needs WebP or benefits from its strengths. Keep the PNG original as your master copy.
Frequently asked questions
Does converting PNG to WebP reduce quality?
WebP is a lossy format, so the image is re-encoded rather than improved. At a high quality setting the difference is not visible for photos.
Will converting PNG to WebP keep transparency?
Yes. WebP supports an alpha channel, so transparent areas are preserved after conversion.
Why convert PNG to WebP?
The most common reasons are compatibility and file size: WebP opens in more apps and websites than PNG in many cases, and switching format can make the file smaller or add features like transparency. Convert when the destination needs WebP specifically, and keep the original if you may need to re-edit it later.
Are my images uploaded to a server?
No. The PNG-to-WebP conversion happens entirely in your browser using the built-in canvas engine — your images never leave your device, so it is safe to convert private or work files.
Is this converter free?
Yes — converting PNG to WebP here is completely free, with no watermark, no account, and no limit on how many images you convert.
