The private way to turn AVI video into MP4 video
Transcoded to MP4 with ffmpeg (when enabled). Pulls a still frame out of an MP4 video. With Morphr, the whole conversion runs inside your browser tab using your browser's built-in decoder — your file is never uploaded to a server, queued, or stored. That makes it a safe choice for personal photos, scanned documents and anything you'd rather not hand to a third party.
Frequently asked questions
- Is it free to convert AVI video to MP4 video?
- Yes — Morphr is completely free, with no limits, watermarks, or sign-up.
- Are my files uploaded to a server?
- No. The conversion runs entirely in your browser, so your AVI video file never leaves your device.
- What do I get converting AVI video to MP4 video?
- A single still frame, saved as MP4 video. Morphr extracts the frame in your browser — it doesn't re-encode the video, so the audio and motion aren't included, just the picture.
- Is there a file size limit?
- Because everything runs locally, there is no upload limit — the practical ceiling is your device’s available memory.
