    PDF Encryption Checker

    Check whether a PDF is encrypted before you send it, on your device. This page cannot add a password: that needs a PDF library that can write encryption, which it does not have yet.

    Same quality bar. Still free. Still no upload.

    Your files never leave your device

    Free to use, with no account, no usage limit and no watermark, because the work runs on your device rather than on our servers.

    This is not a promise about how carefully we handle your upload. There is no upload. The file you choose is read into memory by your own browser, processed there, and handed back as a download — the tool has no server component and makes no network request with your data.

    • Nothing is stored. We never receive the file, so there is no copy to retain, no retention period to disclose, and nothing to delete on request.
    • Nothing is transmitted. No upload endpoint, no analytics payload carrying file contents, no third-party processor.
    • You can verify it. Load this page, disconnect from the internet, and use the tool. It still works, because everything it needs is already on your machine.
    • Nothing persists after you close the tab. Files are held in page memory only — not in local storage, not in a cache, not in a database.

    A note on wording, because it matters: we do not describe these tools as “encrypted.” Encryption protects data that travels to somebody else's computer. Your file does not travel, so there is nothing to encrypt and nothing to intercept — which is a stronger guarantee than encryption, not a weaker one. The page itself is served over HTTPS like the rest of the site.

    This makes the tools safe for material you are contractually barred from uploading to third-party services — client footage under NDA, unreleased campaign assets, anything covered by a confidentiality clause.

    How it works

    1. 1. Drop a PDF

      It is opened in your browser and checked for existing encryption.

    2. 2. See the status

      The file name, size, page count and a clear Encrypted: yes or no.

    3. 3. Read what it means

      Encrypted means it may need a password to open, or only restrict printing or editing. Not encrypted means anyone with the file can open it.

    Questions

    Can this remove a password I forgot?

    No. It only reports whether a file is encrypted. Removing or bypassing a password is not offered here.

    Can it add a password to my PDF?

    Not yet. The PDF library this page uses (pdf-lib) can detect encryption but cannot write it, and a fake lock that any reader ignores would be worse than none.

    What does it tell me about my file?

    Its name, size, page count and whether it is encrypted. Encrypted can mean an open password or only limits on printing, copying or editing.

    Everything on this page works on a file you already have, which is why it costs nothing. Generating something that did not exist (video from a prompt, a voice, a score) runs a model, and that costs credits.
