The toolkit

One app instead of nine.

Each tool does one job properly — real controls, honest previews, and a file size estimate before you commit.

Most used

Video to Audio

Choose any audio track in the file — main, surround or commentary — trim the range you need, then export at up to 320 kbps.

Video to Audio

Pick the track. Trim it. Export it.

Most extractors grab whatever track is first. Forma lists every one in the file and lets you choose before it starts.

  • Main, surround and commentary tracks, with language and codec
  • Frame-accurate trim handles on a real filmstrip
  • Output name, size and duration shown before you convert

Voice Isolate

Clean up a recording in one tap.

Traffic, room hum, a fan in the corner — lift the voice out and keep the take you already have.

  • Preview before and after on the same waveform
  • Strength control, so speech never turns robotic
  • Runs on the phone — interviews stay private

My Creations

Every export, right where you left it.

Finished files land in one library — play them, rename them, share them, or feed them straight back into another tool.

  • Built-in player for video and audio results
  • Filter by tool, sort by date or size
  • Light and dark themes, six accent palettes

FAQ

Before you download.

Does it work without internet?

Yes. Every tool runs on the device, so conversion, trimming and isolation all work in airplane mode.

Is there a watermark or a length cap?

No, and no. Free exports are clean and as long as the source file.

Which formats can it export?

Video: MP4, MKV, MOV, WEBM, GIF and more. Audio: MP3, AAC, WAV, FLAC, OGG, M4A and OPUS.

What happens to my files?

They stay in your storage. Forma asks for media access once and never copies anything off the phone.

Can I set an export as a ringtone?

Yes — Ringtone Maker trims the section you want and sets it in one tap.

Is Premium a subscription?

No. It is a single purchase that stays unlocked on your Play account.
