Runs via our server — files are uploaded and deleted right after processing.
Honest limits
Only the sound is saved: the video's first audio track — if it has several, such as one per language, the first one. A video without sound is refused with a note. The audio file carries no location, device, date, title or chapters from the video. The video file must fit the upload limit of 30 MB without an account, and the audio file the output-size limit like any other download: a long video saved as WAV, which is uncompressed, can pass it — choose MP3 or M4A, a fraction of the size.
How it works
- Choose your video — MP4, MOV, AVI, MKV, WebM, FLV or WMV. MP3 is pre-set; M4A, WAV, FLAC, OGG, AAC, Opus and WMA are in the list.
- Server saves the sound — ffmpeg takes the first audio track from the video and encodes it in the format you chose; the picture is left out.
- Download the audio file — The video is deleted right after, and the audio file carries no location, device or date from it.
When to use it
Use it when only the sound matters: a talk, a lecture, an interview or a voice note that was recorded as a video. An audio file is much smaller than the video, plays in any music or podcast app and opens in an audio editor as it is.
Frequently asked questions
Which audio format should I choose?
MP3 plays everywhere. M4A (AAC) sounds better at the same size and is Apple's default. WAV and FLAC add no further loss, for editing — both are several times the size of an MP3 (WAV uncompressed, FLAC compressed without loss). OGG and Opus are open formats; WMA is a legacy Windows format. Surround sound becomes stereo for MP3, Opus and WMA, and stays for the others.
Why was my video refused?
It has no sound, the file is over the upload limit, or it is in a format FileMorph doesn't read. A video without sound has nothing to save: choose one with sound. A file over the upload limit: export the video at a lower resolution first — the sound stays the same. Another format: save the video as MP4 first.
Do I need an account?
No. The conversion works without an account, and the video is deleted right after.
