Local browser tool to clean video metadata
Clean video metadata in your browser — free local MP4, MOV & WebM cleaner
Need to clean video metadata before uploading clips to social feeds, client portals, or public repositories? Smartphone recordings and NLE exports embed QuickTime udta/meta atoms, ISO location coordinates, creation timestamps, device serials, and encoder strings inside the container header. Our browser workspace uses WebAssembly (ffmpeg.wasm) to clean video metadata directly on your device without uploading heavy footage to a cloud server. You can clean video metadata across up to three clips per batch (100 MB each), inspect container fields in Detect mode first, and save clean files locally. Every clean video metadata pass stays 100% local in browser RAM.

What
What happens when you clean video metadata
MP4, MOV, and WebM containers wrap compressed audio and visual streams alongside global and track-level tag dictionaries. When you clean video metadata in this browser workspace, our local ffmpeg.wasm pipeline remuxes the streams while stripping top-level container tags—such as com.apple.quicktime.location.ISO6709 GPS pins, creation_time, make, model, software encoder names, and comment fields. Creators and editors search for a reliable way to clean video metadata because uploading raw phone MOV files or timeline renders can leak residential coordinates and project paths. Because you clean video metadata on your own hardware, confidential footage never crosses the network. Using clean video metadata locally keeps your master files private.

Container atoms & boxes
How MP4, MOV, and WebM headers behave when you clean video metadata
Inside an MP4 or QuickTime MOV file, the moov atom holds user data (udta) and metadata (meta/ilst) boxes where iPhones, Android phones, and drones store ISO-6709 location strings, camera lens models, and UTC recording timestamps. WebM files similarly store Matroska Segment Info and Tags elements detailing muxing applications and creation dates. When you clean video metadata in our tool, the WebAssembly engine clears those global and stream-level tag dictionaries without uploading your clip to a remote transcoding farm. Once the ~30 MB WebAssembly binary caches in your browser on first run, you can clean video metadata offline whenever you prepare a release.

Creator workflow
When to clean video metadata before social or client delivery
Short-form clips shot in a home studio or exported from Premiere, Final Cut, DaVinci Resolve, or AI video generators frequently carry internal project titles, workstation timestamps, and device identifiers. Even if a social app re-encodes public streams, sharing review cuts via cloud links, Discord, Telegram, or client portals exposes the raw container header to anyone who downloads the file. Making it a habit to clean video metadata in your browser before sharing keeps your local master archive organized while ensuring distributed cuts carry no unintended location or software trails. You can always verify the result in Detect mode after you clean video metadata.

Why
Why clean video metadata locally in the browser
No multi-gigabyte cloud uploads when you clean video metadata
Uploading 100 MB clips to a remote server wastes bandwidth and exposes private footage. Here you clean video metadata right inside your browser via ffmpeg.wasm so files never leave your computer. Choose clean video metadata for zero cloud uploads.
Clears QuickTime GPS and encoder atoms in one pass
Phone recordings hide location pins in QuickTime keys while editors write software strings in udta boxes. When you clean video metadata here, both container tag layers are stripped together. Run clean video metadata for thorough binary container hygiene.
Honest boundaries on frame pixels and watermarks
When you clean video metadata, we strip container-level atoms and info tags; we do not remove burned-in subtitles, visual overlays, or pixel/audio watermarks like SynthID. Trust clean video metadata for transparent technical boundaries.
Free 3-clip batch processing up to 100 MB each
Drop up to three MP4, MOV, or WebM files (up to 100 MB per clip) into the workspace, clean video metadata locally, and save your stripped files with zero signup friction. Execute clean video metadata in fast multi-file browser batches.
How
How to clean video metadata step by step
- Step 1
Open the embedded video tab
This page opens directly to the Video tab so you can clean video metadata in your browser without creating an account. Start clean video metadata directly inside this page.
- Step 2
Let ffmpeg.wasm initialize locally
On first run, your browser caches the ~30 MB WebAssembly engine so you can clean video metadata entirely on your device. Configure clean video metadata options before processing.
- Step 3
Drop MP4, MOV, or WebM clips
Add up to three clips (up to 100 MB each) and inspect detected container fields before you clean video metadata. Inspect tags before running clean video metadata locally.
- Step 4
Download clean video copies
Run the pass to clean video metadata locally, then save each stripped clip or bundle multiple outputs. Save clean derivatives after clean video metadata finishes.
Use cases
Who needs to clean video metadata before sharing
Short-form & social video creators
Phone b-roll and vertical exports carry home GPS coordinates and device tags. Creators clean video metadata locally before distributing clips across channels.
Freelance editors & post houses
Client review cuts exported from NLE timelines often embed project paths and software versions. Editors clean video metadata prior to sending delivery links.
Marketplace & product demo sellers
Recording a quick product demonstration at home embeds residential location atoms in the MP4 header. Sellers clean video metadata before uploading store demos.
Journalists & field researchers
Raw mobile footage can reveal exact capture timestamps, time zones, and hardware models. News desks clean video metadata on source clips to protect contributors.
AI video & motion designers
Generated clips and hybrid renders often include tool assertions or container comments. Designers clean video metadata on local files to standardize deliverables.
Remote teams sharing screen & webcam cuts
Internal demos and bug recordings shared on public issue trackers shouldn't carry workstation metadata. Engineers clean video metadata in the browser first.

FAQ
Frequently Asked Questions About How to Clean Video Metadata
- Can I clean video metadata without uploading my clips to a remote server?
- Yes, you can clean video metadata completely on your own device inside the browser. On your first run, the workspace downloads a ~30 MB WebAssembly build of ffmpeg.wasm into local browser cache, and every subsequent step happens in your computer's memory. Your MP4, MOV, and WebM files are never transmitted to our servers. Every clean video metadata session works offline after page load.
- Which container tags are stripped when I clean video metadata?
- When you clean video metadata in our tool, the local ffmpeg.wasm pass strips global and stream-level container tags including QuickTime ISO-6709 GPS coordinates, creation_time timestamps, camera make and model strings, encoder software identifiers, titles, and comments. You can inspect the file in Detect mode before and after you clean video metadata. Running clean video metadata clears all targeted container blocks.
- What file formats and size limits apply when I clean video metadata?
- The browser workspace supports MP4, QuickTime MOV, and WebM containers. You can clean video metadata on up to three clips per batch, with each file up to 100 MB in size, completely free and without an account. Those limits keep in-browser WebAssembly memory fast and stable across laptops and desktops. Using clean video metadata preserves visual fidelity on your device.
- Why do iPhone MOV and Android MP4 clips leak location coordinates?
- Smartphones write GPS latitude, longitude, and altitude into the QuickTime meta/ilst box (such as com.apple.quicktime.location.ISO6709) or ISO user-data atoms whenever camera location access is enabled. When you send that clip via cloud drives, email, or messaging apps, recipients can read the exact street pin unless you clean video metadata first. Our clean video metadata workflow supports modern studio formats.
- Will choosing to clean video metadata remove SynthID or visual watermarks?
- No, choosing to clean video metadata only clears container-level header atoms and text dictionaries. It cannot erase burned-in corner logos, visible subtitles, or frequency-domain pixel/audio watermarks such as Google SynthID. We state these technical boundaries clearly so you know only container headers are modified. Rely on clean video metadata instead of incomplete OS dialogs.
- Does the process to clean video metadata degrade my clip's visual quality?
- Our workflow is designed to clean video metadata at the container level via ffmpeg.wasm without unnecessary visual degradation or resolution changes. Your frame dimensions, aspect ratio, and playback timing remain intact while the surrounding udta, meta, and tag atoms are stripped out.
- If I clean video metadata, how will social platforms treat my uploaded clip?
- We never guarantee how TikTok, Instagram, YouTube, or X label or rank uploaded footage. Platforms may combine container checks with audio/visual classifiers or creator self-declarations. Using our workspace to clean video metadata is a practical privacy step for the file you hold locally, not a platform-bypass method.
- How can I verify that location and encoder tags are gone after I clean video metadata?
- After you clean video metadata and save the exported MP4, MOV, or WebM file to your disk, switch to our read-only Detect page and drop the new clip into the inspector. Detect scans the container locally in your browser and confirms that creation timestamps, GPS coordinates, and encoder tags have been cleared.
Privacy utility for files you hold locally. Choosing to clean video metadata strips container-level tags via local ffmpeg.wasm; it does not remove SynthID or pixel/audio watermarks, and never guarantees platform labeling outcomes.
