What is a DVR file?
DVR – Windows DVR-MS recording. DVR-MS is the recording format of Windows Media Center: MPEG-2 pictures inside a Windows Media file. Converting makes a new file: the video is decoded and encoded again, so converting from a format that lost detail never brings it back.
DVR Converter →What is an M4A file?
M4A – MPEG-4 audio (M4A). M4A is audio (usually AAC or Apple Lossless) in an MP4 file, the format of iTunes, Apple Music and iPhone voice memos. Converting makes a new file: the sound is decoded and written again, so converting from a lossy format never brings back what was lost.

Frequently asked questions
Is converting DVR to M4A free?
Yes. Everyone gets 25 free credits a day, with no account needed. Conversions on our server use one credit per started minute of work, so most cost a single credit. Credits reset at midnight UTC.
Are my DVR files uploaded anywhere?
This conversion runs on our server, because converting video needs ffmpeg, which does not run in a browser. Your file is sent over an encrypted connection, and both it and the result are deleted 72 hours after the conversion. The server has no internet access while it works on your file.
How large can the DVR file be?
Up to 1 GB per file. This conversion runs on our server, which accepts files up to that size.
Will the M4A look the same as the DVR?
Only the sound is kept: the pictures are left out, and the M4A is made from the first sound track.
Can I convert several DVR files at once?
Yes. Add as many files as you like; they are converted one after another, and each one gets its own Download button.
