WebM is intended for web playback; check codec support in the target browser. WebP is useful for web graphics; transparency and animation depend on the conversion route.
Quality and output
Default WebP output uses lossy encoding. PNG transparency can be retained, but RGB pixels can change. Do not assume a fixed percentage reduction or lossless output.
How to use
- Upload a valid WEBM file.
- Run the conversion to WEBP.
- Download the result and check it before replacing your original.
