I need to lock down some PDF files before sending them out for work, but it has to be done fast on my laptop. What’s the quickest way to add protection without extra steps? ---

That is annoying when you’re up against a deadline. I normally use the password/encryption option in my PDF editor, set an open password, then save a separate protected copy so the original stays untouched. If you also need to stop edits or printing, add permissions too, but remember to send the password separately. ---

Had the same thing last month with some field reports I had to send out. I opened each PDF in Adobe Acrobat on my laptop, clicked Protect, and added a password. It was pretty fast. Not sure if that’s the quickest for everyone but it worked without extra steps for me. ---

Fastest thing I do is put the PDF in a password protected zip with 7-Zip, then send the zip and text the password separately. On a Mac, Preview lets you add a password when you export. If you need the PDF itself locked, LibreOffice sets one when you export as PDF. ---

I lock down my change orders all the time so clients can’t alter the numbers. The easiest route is to use [pdfcap.com](http://pdfcap.com) on your laptop. Just upload the contract, click the protect option, and set a password to stop unauthorised editing. Did that end up working out for you? ---

@nicholasb23 The 7-Zip trick is handy, but watch out, a lot of work email systems strip or block zip attachments. Learned that the hard way when a patron’s form never arrived and we thought it was sent. My tip: the LibreOffice export password works great since the file stays a normal PDF. Just don’t text the password in the same thread as the file. ---

first, check whether you need a password just to open the file or also need editing locked. on a Mac, Preview is quickest: File \> Export as PDF, then turn on Encrypt PDF and set the password and permissions. on Windows, try Word’s Save as PDF \> Options, which can add an open password and editing permissions in supported versions. tell me your laptop OS and which restriction you need, and I can point you to the exact buttons. ---

If you just need a password lock, AltoSignPDF has a protect option, open file, set password, done in a minute. Keep a backup of the original before you add the password, just in case you forget it later.
