Questions

Is it free?

Yes. Convert, cut, and the other everyday tools are free for the first hour of a file, noise removal and voice enhancement for the first minute, and transcription for the first 2 minutes, a few times a day, with no sign-up. For longer files, pay only for what you use — from $0.01 to $0.03 a minute ($0.60 to $1.80 an hour) with no subscription — see pricing.

What happens to my files?

They stay private. Uploads are deleted after 24 hours, and free results after 1 hour.

Which files work?

Audio as WAV, MP3, M4A, AAC, FLAC, OGG, Opus, WebM, AIFF, and video as MP4, MOV, MKV, WebM, AVI. Files up to 10 GB work without an account, and up to 10 hours when signed in. To change formats first, use Convert audio, or pull the sound from a video with MP4 to MP3 or Replace audio in video.
