Forma turns your phone into a complete video and audio workshop. Extract MP3 from a video, cut a clip to the second, merge takes, convert formats, compress a large file for sharing — 15 focused tools in one clean app. No watermark. No sign-up. Everything runs offline on your device, so your files are never uploaded anywhere. ▶ VIDEO TO MP3 — THE ONE PEOPLE COME FOR Most extractors grab whatever audio track comes first.
