Tools for subtitles and audio
Sixteen utilities for what happens before and after a recording: turning it into text, pulling the audio out of a video, making it smaller, cutting a piece out of it, or moving a subtitle file from one format to another. Everything except the transcription itself runs inside your browser and uploads nothing.
