How do I convert an AVI file to SWF using LetsConvert?

Upload your AVI, select SWF as the output format, adjust codec settings like H.263/VP6 and audio quality, then click Convert. Our engine re-encodes frames and audio to Flash-compatible SWF, preserving keyframe intervals.

Why convert AVI to SWF instead of keeping AVI?

SWF offers smaller file sizes for vector-based animations, better transparency support, and direct playback in older Flash players. It's ideal for embedding in legacy web pages and rich media ads.

What happens to alpha channels and audio bitrate when converting AVI to SWF?

AVI alpha channels are mapped to SWF's transparency mask, retaining cut-out edges. Audio is re-encoded to MP3 at up to 160kbps, matching original bitrate when possible. Geometry is flattened into frames, so mesh data is not preserved.

Is AVI-TO-SWF free to use?

Yes, AVI-TO-SWF on LetsConvert is 100% free with no registration or hidden fees required.

Are my uploaded files safe and secure?
