Passwords and documents stay on this device. No password recovery or bypass is provided. Unlocking requires a password you are authorised to use. Open the output to review every page.
Eligible PDF copies include the original colorful logo with Made, Scanned or Printed with FileFatafat branding in a verified clear area or added footer space. Protected originals, strict formats and size limits take priority. Standalone image exports have no visible watermark. Generated download names include _FileFatafat once. Originals are unchanged.
Protect a copy before sharing it
This tool creates an AES-256 password-protected PDF on your device. Use it when the recipient can accept encrypted PDFs and you can send the password separately. A recruitment portal that requires an unlocked certificate may reject an encrypted copy even when its file size is correct.
Choose a PDF you are allowed to use, enter the new password twice and prepare the copy. Download it, open it in a PDF reader and confirm that the password works before you share it. Keep the original separately.
How to use protect PDF
Select the PDF, enter and confirm a new password, then choose Protect PDF. Check the downloaded copy in a PDF reader and retain the password securely.
Check the requirements on your form
This does not provide password recovery, verify a document’s authenticity or prevent a recipient who knows the password from copying information. Password fields are cleared after successful processing; this site cannot retrieve the password for you.
Will my file be uploaded?
No. Processing happens in your browser, including PDF rendering, scanning and ZIP creation. Tool code is downloaded from this website; the documents you select are not sent back.
Can every file reach the requested size?
No. A size limit is a maximum, not an exact guarantee. Detailed or multi-page documents may need a larger limit to remain readable. One KB here is 1,000 bytes. Check clarity and any minimum file size before submission.
Can you recover my password later?
No. The password is processed in the browser and is not sent to FileFatafat.
What if my input is already password protected?
Use Unlock PDF with a password you are authorised to use first, then protect the resulting copy with the new password.
