What you can upload
The file types we accept, the size and length limits per plan, and what to do about the rest.
File types
Audio: MP3, WAV, M4A, AAC, FLAC, OGG, WMA, OPUS. Video: MP4, MOV, AVI, MKV, WEBM, WMV, FLV, M4V, 3GP. With video we use the audio track and ignore the picture, so a screen recording works exactly as well as a voice memo.
Size and length
- Free â up to 50 MB per file, 3 files a day, and only the first 5 minutes are transcribed.
- Standard â up to 2 GB and 5 hours per file, 20 files a day.
- Premium â up to 5 GB and 8 hours per file, no daily limit.
Important
The size limit is about the file, not the recording. An hour of uncompressed WAV can be larger than a two-hour MP4. If you are just over the line, export to MP3 before uploading â it does not hurt accuracy.
Things that will not work
- Documents and images â there is no OCR here, only speech.
- Streaming links and DRM-protected files. Download the file first.
- Silent files, or files where the microphone never picked anything up. You will get an empty transcript rather than an error.
A file that is accepted but still refuses to go through is usually one of a handful of problems â see your file will not upload. If the recording exists but the sound is rough, get a cleaner transcript is the more useful page.
