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. Forma lists every track in the file — main, surround or commentary, with language and codec — and lets you choose. Trim the exact range you need on a real filmstrip, then export MP3, AAC, WAV, FLAC or OGG at up to 320 kbps. The output name, size and duration are shown before you convert.
