PNG to WebP
Convert PNG graphics and screenshots to WebP for smaller assets. The file is encoded in your browser with a quality control.
Drop a PNG UI shot, icon sheet, or diagram when lossless PNG is heavier than you need on the web. This path accepts PNG only, not camera JPEGs.
Canvas writes WebP on this device. The graphic never uploads to convert.
How to use
- Choose a PNG file.
- Set WebP quality and process.
- Download the .webp and check whether edges stay clean enough.
How it works
PNG is great for sharp UI and text. WebP can keep similar edges at a fraction of the bytes when you accept a little loss.
Alpha may flatten depending on the browser encoder. Test logos with transparency before you ship. Camera photos belong on JPG to WebP.
Examples
UI screenshot
A documentation PNG of a settings panel often halves in size as WebP without smearing labels.
Icon
A 512 PNG icon at quality 0.9 can stay crisp for a favicon-sized WebP where JPEG would muddy edges.
FAQ
Can I convert a JPEG here?
No. Use JPG to WebP for photographs.
Does transparency always keep?
It depends on the browser WebP encoder. Check the download against a checkerboard background.
Is this lossless WebP?
Quality below 1.0 is typically lossy. Treat it as a smaller web asset, not an archive master.
Is the PNG uploaded?
No. PNG to WebP is client-side.
