How to Edit Video Metadata Offline — Free Browser Tool

Step 1: Select Your Video File

Click or drag your video file into the metadata editor. MP4, MKV, and MOV files are all supported.

Step 2: Edit the Metadata Fields

Update the title, artist, album, year, genre, description, and any other tags shown in the editor.

Step 3: Save Changes

Click Save. The tool writes the new metadata to the file using FFmpeg.wasm entirely in your browser.

Step 4: Download the Updated File

Download your video with the corrected metadata — no quality loss, no re-encoding.

Fix Incorrect Tags

Videos exported from editors often have generic or missing titles. Correcting metadata helps media players, Plex, and Kodi display files correctly.

Organise Your Library

Adding year, genre, and description tags lets media server software (like Plex or Emby) automatically group and display your video collection correctly.

Remove Sensitive Data

Video files can contain creation timestamps, GPS coordinates, device IDs, and recording software names. Editing metadata removes this before sharing.

Your video never leaves your device. No upload, no server, no data collection at any stage.

Metadata edits are a near-instant remux — no re-encoding, no quality loss.

Once the page loads, metadata editing works without any internet connection.
