## Good to know

- WebM uses lossy compression, so files get much smaller. The default quality is visually lossless for most content; lower it under Options for even smaller files.
- APNG files are typically used for high-quality animated stickers and UI animations, while WebM is best for video on websites and in browsers.
- This conversion runs on FFmpeg (WASM), running locally in your browser — nothing is uploaded and it works even on slow connections.
