Re-wrapping AVI footage as 3GP is what makes it playable and editable outside the device or era it came from, without re-shooting anything. 3GP (3GPP multimedia file) earns its place here: extremely small files built for slow mobile connections. AVI is a Microsoft container from 1992. Old camcorders, screen recorders and archives are full of it, but it lacks modern streaming features and produces large files.
AVI is a Microsoft container from 1992. Old camcorders, screen recorders and archives are full of it, but it lacks modern streaming features and produces large files.
Picture and sound are re-encoded into the 3GP container at a bitrate chosen to keep the result visually close to the AVI source. Resolution, frame rate and duration are preserved; file size usually changes noticeably because AVI and 3GP lean on different codecs. Multiple audio tracks or chapter data may not carry over.
What you gain with 3GP: Extremely small files built for slow mobile connections.
Drop your AVI file above and Morphio decodes it locally, then re-encodes it as 3GP using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Free supports batches of 5 files; Pro supports batches of 250, subject to your device's memory. See exactly how in-browser conversion works.
Open the AVI to 3GP page, drop your video on the drop zone and press convert. Morphio runs an FFmpeg build compiled to WebAssembly that runs inside the page, so the AVI data never leaves your device and no server ever receives a copy.
Audio and video tracks are re-encoded together, so the result stays in sync and plays on standard players. Converting AVI to 3GP only rewrites the container and encoding you asked for — the source file on your disk is never modified.
Yes. The free plan covers 10 conversions a day with files up to 200 MB and adds no watermark or sign-up. Morphio Pro ($5/month, or $29 once for lifetime access) removes the daily cap and raises the per-file limit to 5 GB.
Morphio decodes the AVI file at full fidelity and re-encodes it at a high-quality 3GP setting, so the difference is normally invisible or inaudible. What conversion cannot do is recover detail the original AVI file already threw away.
Yes — Free supports batches of 5 files and 10 conversions per day; Pro supports batches of 250 with no daily conversion cap. Your device's memory can impose a lower practical limit. Only usage counts reach the server, never files.
No. The conversion runs entirely inside your browser, so the file never leaves your device. The page and the required decoder must load first; free usage-limit checks may require a connection.
