How to Strip Identifying Metadata From Files
Heshan Fernando
Co-founder & COO
Files can carry more information than the visible content. Photos may include camera details or location data. Documents may include author names, software versions, comments, or revision information. When a file is shared outside its original context, that metadata can reveal more than intended.
A metadata scrubber helps remove identifying metadata from files in your browser before you publish or send them.
What metadata scrubbing involves
Metadata is descriptive information embedded in or attached to a file. Some of it is harmless and useful, such as dimensions or creation dates. Other fields may identify a person, device, location, organization, or editing history.
Scrubbing means removing or reducing metadata while keeping the file itself usable. The exact result depends on the file type and what metadata it contains.
Why people get stuck here
Most file viewers show the main content, not the hidden details. That makes metadata easy to forget. A clean-looking image or PDF may still include internal fields.
Another issue is workflow. Uploading a sensitive file to a random external service just to remove metadata can create a new privacy problem.
| File Type | Possible Metadata |
|---|---|
| Photos | Camera, date, GPS, device |
| Documents | Author, software, revision info |
| PDFs | Title, producer, creation date |
| Media files | Encoder, timestamps, device data |
What a good scrub looks like
The file stays usable
Removing metadata should not destroy the visible content.
Sensitive fields are reduced
Author, device, location, and internal history are common targets.
The process stays local
Browser-only processing helps avoid uploading private files just to clean them.
Common mistakes to avoid
- Assuming screenshots have no metadata. They can still contain file-level details.
- Sharing original files by habit. Export or scrub before public sharing.
- Relying only on visible content. Hidden fields may remain.
- Using unknown upload services for sensitive documents. Local processing is preferable when possible.
How to do it with Metadata Scrubber
- Open the free Metadata Scrubber.
- Select the file you want to clean.
- Review what metadata can be removed.
- Generate the scrubbed version.
- Share the cleaned file instead of the original.
Because the workflow is browser-only, it is suited for quick privacy checks before external sharing.
Frequently asked questions
Does metadata always include GPS location?
No. GPS data depends on the file type, device settings, and whether location tagging was enabled.
Can metadata scrubbing change the file?
Yes, it can create a cleaned copy. The visible content should remain usable, but always review the result.
Should I keep the original?
For your own records, yes. Share the cleaned copy when privacy matters.
Final thought
Before sharing a file widely, check what travels with it. Metadata cleanup is a small step that can prevent accidental disclosure.
