This app is your tiny audio/video blacksmith : toss in audio or video, hammer out the best part, and walk out with a polished file.

How to use it fast: step 1 load a file, step 2 trim with the start/end handles (or type times), step 3 pick a format and forge your download.

Bonus wisdom: if FFmpeg fails, export a shorter segment or lower bitrate to keep things smooth.
