No re-encoding, so quality is untouched

What a video file says about you

A video carries far more identity than a photo, because it is a container full of boxes and every tool along the chain writes into one. Here is what we find, and remove.

Location

GPS coordinates in QuickTime ©xyz atoms and ISO 6709 tags, plus whole telemetry tracks that log your route second by second.

Camera & phone

Make, model, lens, firmware, vendor codes and the handler names that identify the exact device that recorded the clip.

Editing history

The editor and version that exported the file, project names, render settings and the encoder signature.

Timestamps

Creation and modification times in the container tags and in the mvhd, tkhd and mdhd headers where most tools never look.

AI provenance

C2PA Content Credentials, digital source type tags and the generator names left by AI video tools.

Titles & comments

Titles, descriptions, comments, chapter names, artist and copyright fields and album groupings.

How the video cleaner works

The full pipeline
  1. Step 1

    Upload one video

    Drop an MP4, MOV, WebM, MKV or AVI file, or choose it from your device. Nothing to install and no account.

  2. Step 2

    We analyse the container

    Every tag, atom, handler name, header timestamp and provenance manifest is read and listed for you.

  3. Step 3

    We remove the metadata

    The container is rewritten and the compressed video and audio are copied across without being decoded.

  4. Step 4

    We verify every frame

    Both files are checksummed stream by stream. If a single packet differed you would get an error, not a file.

  5. Step 5

    Download your clean video

    A private link that expires after ten minutes, or delete it yourself the second you've saved it.

Most video tools re-encode. We rewrite the container.

The lazy way to strip video metadata is to decode every frame and encode them again. That is slow, it burns CPU, and it costs you real quality: softer motion, blocking in dark scenes, a smaller file that looks worse. Do it twice and it compounds.

We never decode. The compressed video and audio streams are copied across into a fresh container while the metadata boxes are dropped, the handler names blanked and the header timestamps zeroed. Then both files are checksummed stream by stream. If a single packet differed, you get an error instead of a damaged video.

What we deliberately keep

Removing metadata should never change how your video plays. These are preserved on purpose, and none of them says anything about you.

Resolution
Every pixel dimension is untouched. A 4K clip stays 4K.
Frame rate
Constant or variable, the timing of every frame is preserved.
Bitrate & quality
Nothing is re-compressed, so there is no generation loss at all.
Audio
The same codec, channels and sample rate, copied without decoding.
Orientation
The rotation flag is carried over so portrait clips don't play sideways.
Subtitles
Subtitle tracks stay where the container can hold them.

Video questions, answered

Including the limits of what metadata removal can do.

Does it work on video too?

Yes. The video metadata remover supports MP4, MOV, M4V, WebM, MKV and AVI. It removes metadata and GPS telemetry without re-encoding the video or audio streams.

Does cleaning a video reduce its quality?

No. We never re-encode. The compressed video and audio streams are copied into a fresh container without being decoded, so the resolution, frame rate, bitrate, colour and audio are exactly what you uploaded. Before a file is offered for download we checksum each stream in both files and compare them. If a single packet differed, you would get an error instead of a video.

Which video formats can I clean?

MP4, MOV (QuickTime), M4V, WebM, MKV (Matroska) and AVI, up to 500 MB per file. The container is identified by reading its actual bytes, not by trusting the file extension, so a mislabelled file is still handled correctly or rejected safely.

What metadata does a video actually contain?

More than most people expect. Container tags hold the title, artist, copyright, comments, creation date and the software that exported it. QuickTime and MP4 files add GPS coordinates in a dedicated atom, camera make and model, and handler names that identify the recording device. The mvhd, tkhd and mdhd headers carry creation and modification timestamps that survive almost every other tool. Files from phones and action cameras can also carry a whole timed-metadata track logging your GPS position second by second.

Do you remove GPS location from video?

Yes, in both places it hides. The QuickTime location atom and ISO 6709 tags are removed with the rest of the container metadata, and any timed GPS or telemetry track — GoPro GPMF, Apple mebx, Google CAMM, Sony RTMD — is dropped entirely rather than copied across. Those tracks are the bigger risk, because they are a continuous log of where you went, and most metadata tools never touch them.

Will my portrait video end up sideways?

No. Phone videos are recorded in landscape and carry a rotation flag telling players to turn the picture. That flag is not personal information, so we read it before cleaning and write it back afterwards, then confirm it survived. Rotation is part of the verification step, so a clip that lost it would never be offered for download.

How long does cleaning a video take?

Usually a few seconds, because nothing is re-encoded. Most of the wait is your upload. A 20 MB clip is typically cleaned and verified in under five seconds on our hardware; a 500 MB file takes longer to transfer than to clean.

Why is my cleaned video a slightly different size?

Because the metadata is gone and the container has been rebuilt. A phone video can carry tens of kilobytes of tags, atoms and a GPS track; removing them makes the file smaller. MP4 and MOV files are also written with the index at the front so they start playing before they finish downloading, which can shift a few hundred bytes around. The video and audio data itself is byte for byte what you uploaded.

Does removing metadata make an AI-generated video undetectable?

No, and we don't claim it does. Some AI video tools also embed invisible watermarks into the picture itself, and because we never touch the frames, those remain. What we remove is the readable information attached to the file: Content Credentials, generator names, prompts, timestamps and location. If a platform or client requires you to disclose AI-generated work, removing metadata doesn't change that obligation.

Can I clean more than one video at a time?

Not at the moment. Video processing is far heavier than image processing, so each upload gets a dedicated worker and the queue stays short and predictable for everyone. Images can still be cleaned 20 at a time.

Cleaning images too?

The image cleaner strips EXIF, GPS, AI prompts and Content Credentials from JPG, PNG and WebP, with the same lossless guarantee.
