Just make sure to cancel before the seven days are up or you’ll be charged $14.99 plus tax for the full month. The only requirement here is that you will have to supply your credit card information to download the free trial. If you need a password just this one time or for the next several days, snag a free seven-day trial for Acrobat Pro. Both versions support password protection, so you can save yourself a few dollars here by going with the cheaper Standard plan. Acrobat Standard DC will cost you $12.99 a month for an annual subscription or $22.99 a month for a monthly subscription. If you pay for Acrobat, Acrobat Pro DC will run you $14.99 a month for an annual subscription or $24.99 a month for a monthly subscription.
Instead, a variety of third-party programs and online services will let you slap a password onto your file for free. You could purchase the full Adobe Acrobat program, but that’s a pricey prospect if you require only the occasional password.
