Send a recording that's too big to send
The record is the product; accuracy and provenance are non-negotiable.
The chain
Get the recording out of Android recorder apps
Most recorder apps save to Internal storage/Recordings (or the app's folder); share directly or pull via Files/USB. Formats vary: M4A, AMR, WAV, 3GA. AMR/3GA from older apps transcribe fine but convert to MP3 first if another tool rejects them.
Compress to speech-optimized Opus
An hour becomes ~20 MB; ten minutes ~3.5 MB — under every attachment cap.
For legal teams: Audio evidence copies move under attachment limits.

Is my file uploaded during the preparation steps?
No — the tools-online steps (extract, compress, trim, convert, clean up) process the file locally in your browser. Audio only uploads when you choose to transcribe it.
