Is it possible to edit a secured PDF? Sure! In this article, we’ll explain how to remove security from a PDF to edit it.

Limiting access to a PDF by setting passwords and restricting certain features, such as editing or printing, can sometimes be useful, especially if we’rere talking about important documents that shouldn’t be modified. But password-protected PDFs can still be accessed, edited, and printed by removing their encryption. With Smallpdf, unlocking your file for editing is easy.

A secured PDF document should only be edited by its author. Make sure you have the rights to remove the protection on your file before starting.

  3. Wait for the PDF to unlock, then select “Edit PDF” to start editing the file.

  4. Once you’re done modifying your document, click the download button to save your newly-edited PDF.
