SecurePDF

SecurePDF

Robust, Fast, and Secure Batch PDF Password and Permission Management.

SecurePDF turns what used to be a document-by-document chore into a single-click batch operation. Built natively for macOS and Windows, it lets you apply or strip password security, set granular user permissions, and update metadata across entire directories of PDF files in seconds — all processed locally on your machine with no cloud exposure.

Key Features

Batch Password Management

Add, remove, or modify open-document passwords and permission passwords across hundreds of PDF files simultaneously — drag and drop entire folders to process in a single run.

AES-256 Encryption

Protect PDF documents with RC4-128, AES-128, or AES-256 bit encryption — choose the level appropriate for your target PDF reader compatibility and security requirements.

Granular Permission Controls

Selectively restrict or enable high-resolution printing, text and graphic copying, content modification, form filling, and annotation additions — applied consistently across your entire file batch.

Batch Security Removal

Remove open passwords and permission restrictions in batch from authorised files — instantly preparing documents for public release, internal archiving, or merging workflows.

Batch Metadata Editing

Modify Title, Author, Subject, and Keywords across multiple PDF documents simultaneously — keeping your digital document library consistently organised and searchable.

Save or Save As

Choose to overwrite original PDF files in place with the modified version, or export all modified files as new files to a separate destination — full control over your output workflow.

File List Sorting

Sort the PDF processing queue by name, creation date, file size, page count, width, and height — making it easy to organise and prioritise large file batches before processing.

Standalone & Fully Private

No Adobe Acrobat, internet connection, or cloud service required. All security processing runs natively on your Mac or Windows PC — your sensitive files never leave your device.

Brilliant

I wanted something that would remove restrictions from PDFs and formerly used a free app. That free app was not able to properly convert PDFs that had an invisible watermark—the converted file had made the watermark visible. Looking around for other apps I found some costing $30 to $40, so I thought I would try this relatively cheap offering. Do not be misled by its low price, this app rocks, it did the job quickly and perfectly. Money well…

It does exactly what it says it will do

This program will do exactly what is asked for, batch or single edit the security settings and meta info for PDFs. No problem. This is great because preview will not give easily give you these details where this program will and suppots RC4 and AES encryption.

Excellent as long as you know the password

This App has gotten some poor reviews by people who don't understand what it's for. The intended use case is to remove password protection from PDF files in bulk. You still have to know the password. If you have folders full of PDF files that you want to protect or unprotect, it makes quick work of updating them all in place. At $1.99 it's a great value.

Saved me a lot of time

I had over 100 pdf files I needed to remove the passwords and this app did it in about 20 seconds. All files had the same password and I knew it, but wihout the app it would've taken me hours to manually remove the passwords. You simply drag the folder, enter the password and it will keep the same folder/subfolders structure, file location and names, but now without the password.

Easily did what I needed it to do.

I had purchased a couple of books that were delivered in a password protected pdf format. I wanted to be able to open these books on my different tablets without having to enter a password every time. Purchased this software, opened each protected pdf, turned off the security, saved and bye bye password. Note, you need to know the password of the protected pdf you are opening.

Easy to use, does what it says, great value

I needed this app to rationalise the passwords across a whole archive of pdfs. It is very straightforward to use, works quickly and does just what it claims. For the low price it seems very good value.

I had to remove password for a bunch of PDFs and this tool did exactly what it said. The process was swift and I had no issues using it. easy to use.

Excellent product

Works flawlessly but you must quit Acrobat Reader must before using SecurePDF. E-mail support is almost instant and they solved my problem (that text could still be copied) very promptly

Works like a charm!!!

Not sure what all these negative reviews are complaining about. I've been using this app to unlock passworded PDF files for the past three months for work and this app has worked flawlessly. I would recommend this to anyone that needs to unlock PDFs on the fly.

Does exactly what it says and for very little outlay. To remove password protection simply select the document and "save as" with no security - simple.
