Convert PNG to WebP
WebP can reduce the size of many photographs and graphics compared with PNG, especially when a modest lossy quality is acceptable. The result retains transparency where the browser encoder supports it.

How it works
Three steps, entirely on your device
- 1
Add PNG files.
- 2
Set WebP quality and optional dimensions.
- 3
Convert and compare sizes before downloading.
Privacy and support
PNG-to-WebP conversion runs on the device and begins only after the browser proves it can create a real WebP file.
Supported formats
PNG input and WebP output are available when the browser passes a WebP encoding test.
Limitations
- Lossy WebP may soften sharp graphic edges.
- Animated PNG is not preserved.
- Some highly optimized PNG graphics can be smaller than WebP.
FAQ
Frequently asked questions
Will transparency remain after PNG to WebP?
The WebP encoder used by current browsers supports alpha transparency, but you should always inspect the generated preview.
Why is WebP unavailable in my browser?
The page disables processing when a real canvas encoding test does not return WebP.
Should logos always become WebP?
Not necessarily. Simple transparent logos can remain smaller and sharper as PNG or SVG.
