Why unlock locally

Your documents stay yours

The files people lock are the ones that matter most — tax returns, bank statements, contracts, IDs. They are the last files you should upload to a random website.

Nothing to trust

No server, no queue, no link that expires. Resera reads the file, removes the password and writes the copy — entirely on your machine.

It even works on a plane

Fully offline. There is no account to sign into and no connection to wait for.

How it works

Drop in your PDFs

Drag one file or a whole folder's worth. Resera shows what each one needs.

Type the password you know

Use the password you already have for the document. One password unlocks the batch.

Save the unlocked copy

A clean PDF is written next to the original. The original is left untouched.

Already-openable but restricted PDFs — the kind that block printing or copying — carry only owner restrictions. Resera clears those in one click, with no password needed.

Built the Cherishvale way

Batch by default

Unlock a single file or fifty in one go. No daily caps, no per-file charges.

Both kinds of lock

Handles files that need a password to open, and files that open but restrict printing, copying or editing.

Instant, any size

There is no waiting queue and no re-upload. Even large documents are processed in place.

No limits, no watermark

Unlimited pages, unlimited files, nothing stamped over your document.

Private by architecture

Not "we promise not to look" — there is nothing to look at, because nothing is ever sent.

Pay once

One purchase, yours to keep. Never a subscription.

Questions

Do I need the password?

Yes. Resera removes a password you already know. It is not a password cracker and cannot recover a password you have forgotten.

What about PDFs I can open but can't print or copy?

Those carry only owner restrictions rather than an open password. Resera removes those in one click, with no password required.

Is it really offline?

Completely. Resera makes no network requests — no telemetry, no accounts, no update pings. You can run it with the network disconnected.

Which systems?

Windows, macOS and Linux, from a single codebase.

On privacy

Resera runs entirely on your machine. Unlocking a PDF opens the file, removes the password and writes a copy beside it; the original is never modified. No file, filename or password is ever transmitted, logged or stored anywhere.
