STEP 3. Upload PDF File:

STEP 4. Insert the User (Open) Password (must be known to you):

STEP 5. Decrypt the Uploaded PDF File:

NOTE 1: There are two PDF password types - user (open) password and owner (restrictions) password. The user password (also called open password) protects a PDF file from opening. The owner (restrictions) password sets certain restrictions (to protect a PDF file from printing, inserting, deleting, and extracting pages, entering form data, signing, creating template pages, etc.). A PDF file may either be not encrypted at all or encrypted either only by a user (open) password, only by an owner (restrictions) password, or by both passwords.

NOTE 2: This operation assumes that you know the user (open) password. Otherwise, please submit your file to recover the user (open) password.

NOTE 3: If the file is locked by both a user (open) password and an owner (restrictions) password, then the user (open) password will be removed automatically by removing known owner (restrictions) password. In contrast, the owner (restrictions) password will not be removed automatically by removing a known user (open) password.

NOTE 4: This operation assumes that at the time of removing the user (open) password, the file is not secured by an owner (restrictions) password. Otherwise, please submit your file for owner (restrictions) password decryption.

NOTE 5: Any encryption (including encryption by Adobe Acrobat full program) can (in certain cases) affect fonts, Javascript code, fields, and general file appearance. In such cases, a decryption (even by known password) may not restore the original (pre-encryption) fonts, Javascript, fields, and file appearance.

NOTE 6: Decryption by a known password usually affects neither fonts, nor Javascript code, nor fields, nor general file appearance. In contrast, removal of an unknown password can (in certain cases) affect Javascript code and fields, and thus can create a "mess". By this reason, in general, if the password is known, decryption should be done by utilizing the known password.

NOTE 7: The algorithm of this operation will detect and mark by a corresponding error message any input file that:

has not been successfully uploaded, or
has a non-PDF extension, or
has the PDF extension but a non-PDF structure, or
is a corrupted PDF, or
is a PDF encrypted by an owner (restrictions) password, or
is a PDF not encrypted by a user (open) password.

NOTE 8: The algorithm of this operation will accept and successfully process any file (other than listed above), even if the file:

is a PDF with a static XFA structure, or
is a PDF with a dynamic XFA structure.

NOTE 9: The algorithm of this operation will detect and mark by a corresponding error message a missed or incorrect password.

NOTE 10: XFA vs PDF: PDF File Type vs PDF File Extension.

NOTE 11: Error Message: "To view the full contents of this document, you need ..."

NOTE 12: Error Message: "Please wait... If this message is not eventually replaced ..."

NOTE 13: How to Download Your Output Files.

NOTE 14: Your Privacy: Deleting Your Output Files.
