Edit Video Metadata

About Video Metadata Editor

This online tool allows you to edit video metadata tags directly in your browser. Add or change title, artist, album, year, and description embedded in your video files. Perfect for organizing video libraries, adding credits, or improving file information. Video streams are copied without re-encoding, preserving 100% quality. All processing happens locally for complete privacy.

What video formats are supported?

You can upload and edit metadata for MP4, WebM, and MOV video files.

What metadata can I view?

The tool reads the real values straight from FFmpeg's own probe: file name, size and format, plus video resolution, codec, frame rate and bitrate, and the audio codec and bitrate. These are parsed from the file, not estimated.

What metadata can I edit, and which FFmpeg keys are used?

You can edit Title (title), Artist (artist), Album (album), Year (mapped to the date key), Comment (comment) and Description (description). These tags are embedded directly in the video container. Note that MP4/MOV use 3GPP/iTunes-style atoms while WebM/Matroska use their own tag namespace, so a generic 'comment' may be ignored by some players such as QuickTime.

How do I remove all metadata for privacy?

Turn on 'Remove all metadata (privacy)' before saving. Under the hood the tool runs FFmpeg with -map_metadata -1, which strips every existing tag - GPS location, creation_time, device and software signatures, even chapters - producing a clean, anonymized file. This is ideal before publishing footage you don't want fingerprinted.

Will editing metadata affect video quality?

No! The video and audio streams are copied without re-encoding. Only metadata tags are updated, preserving 100% original quality.

Why can't I edit some properties?

Technical properties like codec, bitrate, and resolution cannot be edited as they are intrinsic to the video encoding. To change these, you need to re-encode the video.

Is my video file safe?

Absolutely! All processing happens directly in your browser using FFmpeg.wasm (WebAssembly). Your video file is never uploaded to any server. Everything stays private on your device.

Can I preview the video?

Yes! You can preview the video to verify it plays correctly with the updated metadata.

How long does processing take?

Since we're only updating metadata (not re-encoding), processing is very fast - typically 5-10 seconds regardless of video length.
