Is this online MP4 to AVI converter really free?

Yes, FrameNet offers completely free conversion for MP4 files to AVI format for standard usage. No signup, download, or installation needed to use our basic free MP4 converter features.

Does converting MP4 to AVI reduce quality?

Quality changes depend on the specific MP4 and AVI formats and codecs. Converting between two lossy formats (like MP4, MP3, AAC, OGG Vorbis, WebM VP9) involves re-encoding which *can* slightly reduce quality, but our online converter uses high-quality defaults to minimize this. Converting from a lossless format (like WAV, FLAC, AVI/MOV with lossless codecs) to a lossy one *will* reduce quality to achieve smaller file sizes. Converting *to* a lossless format generally preserves the source quality (but won't improve it if the source was lossy). FrameNet aims for the best possible quality output for your chosen AVI format.

Will the AVI file size be different from the MP4 file?

Generally, yes. Converting from a more compressed format like MP4 to a less compressed or lossless format like AVI will likely result in a larger file size. Use our free online converter to see the exact result for your file.

How fast is the MP4 to AVI conversion process?
