Trim MKV files

Upload an MKV file, select the part you want to keep, and trim it. Trimming only the end is lossless; cutting from the start re-encodes the video so the cut lands exactly where you set it.

Your file never leaves your device. All processing happens right in your browser, and nothing is uploaded to a server.

Matroska trimming without desktop tools

Long OBS recordings and archived MKVs cut down to size right in the browser. End-only trims ride the lossless copy path; start cuts re-encode at high quality for exact placement.
