Subscription Vs. Perpetual Licensing
With perpetual licensing, you pay for the license once and own it forever.
With 1 year subscription licensing, you pay an annual fee and will need to pay that fee every year to maintain your licenses. You are automatically entitled to any new features or service updates while your subscription is active. You also get access to the Acrobat DC on your smartphone, Internet browser, and other capabilities such as e-signing, sending, tracking, and managing documents.
