When not to convert GIF to SWF
- Skip SWF for archival masters: lossy compression discards detail, so keep the GIF original.
- Flatten transparency first: SWF has no alpha channel, so composite GIF over a background color.
Limits
Starting point: GIF - 256-color animation with 1-bit transparency. Limited to 256 colors per frame, so gradients may band. Only the embedded video track converts; scripts and buttons are dropped. Set the quality slider near 80-90 for SWF photos from GIF, and keep dimensions matched to the source.
How conversion works
Conversion runs entirely in your browser with the WASM image engine. Files never leave your device.
