FAQ

Foire aux questions

Can I remove the password from a PDF if I know the password?
Yes! Our Unlock PDF tool is specifically designed to decrypt and strip password protection from files you are authorized to access, allowing you to save an unencrypted copy.
Does this tool crack or bypass passwords without authorization?
No. We strictly adhere to digital security standards and legal protections. You must provide the valid password to decrypt the file.
Will removing the password change the formatting of my PDF?
Not at all. Decryption simply strips the encryption envelope while leaving all textual content, styling, images, and layout pristine.
Is my password sent to your servers?
No. The decryption calculation executes 100% locally in your browser memory using Web Crypto APIs. Nothing is transmitted over the internet.
