For doing the work of pricier software
▪LibreOffice is a “more than capable” substitute for the Microsoft Office suite—and it’s free. Now elegant rather than merely functional, it can be used to open and edit Word documents, Excel spreadsheets, and PowerPoint presentations.
▪GIMP is a free image-manipulation program that “can work pretty much exactly like Photoshop when you need it to.” Paint.net is another good option, but only for Windows users.
▪Avira (for Windows) and Sophos (for Macs) are solid antivirus programs. Combine them with the anti-malware program MalwareBytes and you’ll have strong protection at no cost.
▪DaVinci Resolve isn’t easily mastered, but it does offer a full set of video-editing tools.
▪LMMS is a powerful alternative to pricey music editing and mixing programs like GarageB and and Pro Tools.
