Obviously, that's more expensive, but it gives you access to Adobe's whole range of creative apps, along with a range of other benefits. However, if you think you're going to want to use more than one Adobe app, it might make more sense to go for the Adobe Creative Cloud All Apps subscription. That subscription also gives you Adobe Portfolio, Adobe Fonts, and Adobe Spark. The cheapest is to subscribe to InDesign alone (see the first of the two links above). Once you've decided the software is definitely for you, the only way to buy InDesign is through a Creative Cloud subscription, for which you pay either monthly or annually. How do I buy InDesign CC? View Deal View Deal The likelihood of downloading viruses and malware bundled in with the software make it very much a false economy. Downloading a pirated version from the murkier parts of the internet is illegal, and it’s also a big risk for the security of your devices and data. Taking out a trial is the only legit way to download InDesign for free. If you don’t cancel, Adobe will start to bill you for a subscription, so keep your eye on the calendar if you decide you don't want to continue with the software. You’ll have to provide your credit card details to start the trial, but if you cancel your subscription before the end of the trial, you won’t be charged a penny.
