Buyer's guide
How to choose a protect pdf
When protecting a PDF, the most important factor is whether the tool enforces the specific permissions you need, such as preventing printing or editing. If you are sharing the file with others, choose a service that deletes uploaded documents after processing, like PDF24 or PlumeDocs, rather than one that retains your files. For occasional use where you just need a password without extra settings, MyDocFlow offers the simplest path with no account required.
Questions
Protect PDF FAQ
- Can I remove password protection from a PDF later?
- Yes, but you typically need the original password to unlock the file. Some online tools offer unlocking features, but they may require you to upload the protected PDF and enter the password to remove the restriction.
- Do these tools work on mobile devices?
- Most of these PDF protectors are browser-based and work on both computers and mobile devices as long as you have a stable internet connection. PlumeDocs specifically mentions it works on any device.
- Is my PDF content safe during upload?
- PDF24 states files are automatically deleted from their servers after one hour, and PlumeDocs emphasizes that processing happens on your device with nothing uploaded. For sensitive documents, review each tool's privacy policy before uploading.
- Can I set different permissions like allowing print but not edit?
- PDF24 and PDF Candy both mention restricting permissions such as printing, copying, or editing. MyDocFlow and PlumeDocs focus on password-based opening protection, with PlumeDocs noting AES-256 encryption but fewer documented permission options.
- What is the typical file size limit for these free tools?
