About
On https://freeaudioconverter.net, you can:
- Convert an audio file to another format - MP3, AAC, WAV, Opus, Vorbis (.ogg), FLAC, ALAC, AC3, DTS or CAF.
- Convert a video to an audio-only file (to any of the above formats).
- Convert a video to the MP4 or MKV format.
- Change the audio codec of a video to MP3, AAC, AC3, DTS, WAV, FLAC or ALAC.
- Trim a video or audio file (will not work if using the Safari browser).
- NEW: Download a YouTube video or the audio only. https://freeaudioconverter.net/yt
How does it work?
Your file is uploaded to a server, where the conversion/file trimming takes place. On completion, the file is sent to your browser to be downloaded.
Features:
- You can see the file upload progress as a percentage and also amount uploaded (MB) in realtime.
- Upload completion time is shown in realtime.
- Whilst the file is being converted, you can see how far into the file the encoder currently is. This information is updated every second.
Supported filetypes:
Many filetypes are supported, click here for details. Support for other filetypes may be added, feel free to contact me to enquire.
To-do:
The file trimmer will not work when using the Safari browser as it does not support the HTML <input type="time">.
I may try to find another user-friendly way to allow the user to input their desired start and end time that is compatible with all browsers. Feel free to submit a pull request if you know of a good alternative implementation that is compatible with all browsers.
