Audio & Video Tools
Audio and video work is where "free online" tools run out of patience fastest: file limits, watermarks, quality ceilings. This section covers format converters, transcription and subtitle tools, and AI generation for music and video. Compare them on actual output quality and on how much work you can finish before a tool asks for money.
How to choose
Transcribe on the cloud but edit locally if you can. For format conversion, a free desktop tool beats most websites. When you evaluate AI generation, compare one real project end to end, not ten demo videos.
