How to Convert PNG to WebP in Your Browser
PNG works well for graphics with transparency, but many websites prefer WebP for delivery. This guide covers browser-local PNG to WebP conversion on Looty Tools.

Steps
- Open /tools/png-to-webp.
- Choose a .png file within the 25 MB and 8,192 px limits.
- Adjust WebP quality if needed (default 90%).
- Select Convert & download and save the .webp.
Transparency without white flattening
This converter does not paint a white background. When the browser WebP encoder supports alpha, transparent PNG pixels can remain transparent.
Quality is not lossless
The WebP quality slider uses canvas encoding. That is lossy. Do not expect pixel-perfect lossless WebP from this tool.
Browser encoding support
If canvas cannot encode image/webp, the tool shows a clear error, downloads nothing, and does not count usage.
