- Set quality and inspect the transparency note when relevant.
- Convert to WebP and download the measured output.
02 / DETAILS
About this conversion
Create WebP outputs in the browser with a quality setting. Transparent pixels from PNG can be preserved by the WebP encoder.
The encoder creates a new WebP file and reports its size. It may be larger than a source that is already highly optimized; no smaller-size claim is made without measuring it.
Limits to know
Each input is limited to 40 MiB and 16 megapixels so the browser has a safer memory budget. Very large dimensions can still exceed the memory available on a phone.
Processing runs in this browser. Originals are not overwritten, and the output size is measured in bytes before download. Keep a backup of important files.
03 / FAQ
Questions people ask
Can WebP preserve transparency?
Yes, the browser encodes alpha when the source supports it.
Will a WebP output always be smaller?
No. Size depends on source, content, and quality. The tool shows the actual bytes.
