How the audio and video tools work
Your browser already knows how to play MP3, M4A, WAV and most phone videos. These tools use that same decoder to open the file inside this tab, do the work there and hand back a new file. Interviews, voice notes and family videos are never uploaded. Sound comes back as WAV, which every editor and phone can open.
Which tool for which problem
- A recording is full of long pauses: remove the silence, or shorten each pause instead of cutting it.
- A voice recording hisses, hums or rumbles: clean it up.
- The sound plays in one ear only, or sounds hollow: fix the stereo.
- Some files are much louder than others: match their loudness to one level, such as −16 LUFS for a podcast.
- A lecture is too slow or a song too fast: change the speed without the chipmunk voice, or shift the pitch alone.
- A sound should repeat without a click: make a seamless loop.
- A phone video plays sideways: rotate it without re-encoding.
- A clip has to go into a chat or an email: turn it into a small GIF under a size you choose.
- You need a still from a video: save frames as images, or a contact sheet of the whole clip.
- Subtitles come too early, too late or drift: fix their timing and convert between SRT and VTT.
Questions
Are my recordings uploaded?
No. The file is read and processed in this browser tab. Once the page has loaded you can go offline and the tools still work.
Which formats can I open?
Whatever your browser can play: MP3, WAV, M4A and AAC, FLAC and Ogg in most browsers, and the sound track of MP4, MOV and WebM videos. Safari and Chrome support slightly different sets, so if one browser refuses a file, try another.
Why is the result a WAV file?
Browsers can read compressed audio but cannot save MP3 or AAC on their own. WAV keeps the full quality and opens everywhere; convert it to MP3 afterwards if you need a smaller file.
Is there a length limit?
fixmint sets none, but a long recording has to fit in your device’s memory once it is unpacked. An hour of stereo sound needs roughly 1.4 GB, so very long files work best on a computer.
