Question 1

Are my files uploaded to a server?

Accepted Answer

No. Every tool runs in your browser using an on-device PDF engine. You can verify it in your browser's network panel: running a tool produces no request containing your document.

Question 2

What can I do for free?

Accepted Answer

Organizing, editing and converting tools work on Free within stated limits on file size, page count and exports per day. Exports are never watermarked.

Question 3

How does the 48-hour Pass work?

Accepted Answer

It is a single payment that unlocks premium tools for 48 hours from purchase. It does not renew and nothing is charged again when it expires.

Question 4

Do you support password-protected PDFs?

Accepted Answer

Yes, if you know the password. Unlock PDF removes protection after you enter the correct open password. We cannot and do not bypass encryption.

Question 5

What happens to a digitally signed PDF?

Accepted Answer

The signature is detected and you are warned before export: any modification invalidates an existing digital signature. You decide whether to continue.

Question 6

Why does redacted text stop being selectable?

Accepted Answer

Redaction rebuilds affected pages from pixels so the removed content cannot be recovered. Losing the text layer on those pages is the cost of a redaction that actually works.

Question 7

Does OCR run locally too?

Accepted Answer

Yes. The recognition engine and its language data are served from this site and run in your browser, so scanned pages are never sent anywhere.

Question 8

Do I need an account?

Accepted Answer

Only to buy or restore a plan. Tools work without signing in, and an account never stores your documents.
