Barecopy vs online metadata removers
Search for a metadata remover and you will find dozens of free web tools. Most of them work well enough. But there is one question that matters more than any feature when the file is sensitive, and it is the one almost none of them answer plainly: does my file get uploaded?
The upload question
A large share of free online metadata removers process your file on their server. You choose a file, it is uploaded, cleaned somewhere you cannot see, and a copy is sent back. For a holiday photo that is fine. For a contract, a medical form, a document with a client's name in it, or anything you are cleaning precisely because it is sensitive, it is the wrong trade — you have handed the file to a stranger's computer to remove the traces of yourself from it.
Server processing is not automatically malicious. Reputable services delete files promptly. But "trust our retention policy" is a weaker promise than "the file never left your device", and you usually cannot verify the former.
How Barecopy is different
Barecopy does all of its work in JavaScript inside your browser tab. The file is read, analysed and cleaned locally, and the result is handed back by the page itself. Nothing is uploaded — not to us, not to anyone. Two things back that up beyond our word:
- A Content-Security-Policy on the site restricts where the page is allowed to send data, so exfiltrating file contents is blocked by the browser itself, not just by our good intentions.
- It works offline. Load the page, disconnect, and it still cleans files — which is only possible because there was never a server in the loop.
On top of privacy, Barecopy goes deeper than a typical stripper: as well as standard metadata it cleans content-level leaks in Office files — tracked changes, comments, reviewer identities, speaker notes — and then re-scans the result to confirm the fields are actually gone.

| Typical online remover | Barecopy | |
|---|---|---|
| File leaves your device | Often uploadedserver processing | Neverin-browser |
| Verifiable privacy | Policy you must trust | CSP-enforced + works offline |
| Standard metadata removal | Usually | Yes |
| Tracked changes & comments | Rarely | Yes, opt-in |
Reviewer identities (people.xml) | Almost never | Yes |
| Re-scan to confirm clean | Rare | Yes |
| Record of what was removed | Rare | Optional PDF + SHA-256 |
| Works behind corporate proxies | Varies | Yesself-hosted, no CDNs |
"Typical online remover" describes the common server-upload pattern; individual tools vary, and some are browser-based too. The point is to check, not to assume — the Network tab tells you in seconds.
How to choose one
For a non-sensitive file, any working tool is fine — pick whatever is convenient. For anything you would not want a stranger to keep a copy of, the deciding question is not the feature list; it is whether the file is uploaded. Prefer a tool you can verify processes locally, and take thirty seconds to verify it. Barecopy is built to pass that test, and to do more once you trust it.
Clean a file without it leaving your device
Drop a document or photo on Barecopy, open your Network tab, and watch: nothing is uploaded. It shows what the file reveals, removes it, and re-scans to confirm.
Open Barecopy →Frequently asked
How can I tell if an online tool uploads my file?
Open Developer Tools, go to the Network tab, and process a file while watching. An upload shows as a large request carrying the file. A browser-only tool like Barecopy makes no such request — and still works with your internet switched off.
Is browser processing less thorough than server processing?
No — where you run the code is a privacy decision, not a capability one. Barecopy cleans standard metadata plus content-level Office leaks and verifies the result, all locally.
Is this comparison biased?
We make Barecopy, so it is a considered case rather than a neutral one. But the upload question is checkable in your own browser in under a minute, whichever tool you are weighing — so you do not have to take our word for anything here.
