How did PDF editor work for you?
Please don't include personal details. Your files are never sent with a review.
Thanks! We read every review, and it shapes what we build next.
How the protection works
The PDF is encrypted with AES-256, the strongest standard PDF encryption, and can only be opened with the password. It works in every PDF reader, including phone apps, Adobe Reader, Chrome and Edge. Editing is blocked for anyone without the owner password, which is generated at random.
Choosing a password
Use something the receiver can be told separately, such as a date of birth plus the last four digits of a phone number, the way banks protect statements. Don't send the password in the same email as the file. There's no way to recover a forgotten password, so keep a note of it.
Share it safely
Protect salary slips, bank statements, medical reports and ID copies before emailing or uploading them to shared drives. Set a KB limit if an email or portal limits size; the password is applied after compression, so the file stays protected.
Use cases
Sending salary slips and statements
Lock a PDF with a password before emailing salary slips, bank statements or medical reports.
Client documents
Protect contracts and invoices you share with clients so only they can open them.
Documents on shared devices
Keep personal PDFs on a family or office computer from being opened by others.
Questions
Can I remove the password later?
Yes. Open the protected PDF here with its password, then download it with the password field left empty.
Does the password stop printing?
Untick Allow printing and readers that respect PDF permissions won't print it.
Is AES-256 secure?
Yes. With a strong password, it can't be opened without the password.
Is my PDF uploaded to add the password?
No. The encryption happens in your browser.
