We usually rely on expensive computer software to edit photos and videos, handle office affairs, and protect computers from malware. But these are not our only choices. Commercial studios usually offer basic versions of their products for free. In other cases, some volunteers believed that the software should be free and developed open source alternatives. Through these pathways, you can find free programs that cover almost all computing tasks.

However, not all free apps are equally excellent. We have filtered out the 10 best free alternatives from a wide range of options that can replace expensive computer programs.
LibreOffice is one of the best choices if you need a comprehensive office suite that does almost everything Microsoft Office does. While it lacks the visuals of more expensive products, it can perform the same functionality and can work seamlessly with files created in Office and other formats.
This suite is suitable for Windows, macOS, Linux, and even Android and iOS, including six main programs: Writer (word processing), Calc (spreadsheet), Impress (presentation), Base (database), Draw (charts) Math (formula writing). These cover the basic features you need to stay productive at work, and each program includes some templates to get you started.
Individual applications also include their own capabilities, from complex chart-making options in Calc spreadsheets to watermarks of documents created in Writer.

If you work frequently on multiple devices or collaborate with colleagues frequently, you may prefer a cloud-based Microsoft Office alternative: Google Drive suite.
Because this set of applications run online, you can access them from any browser on any computer and easily share files to collaborate with others. In addition, Drive is tightly integrated with other Google's web services such as Gmail.
The disadvantage is that Drive does not provide the same functionality as Microsoft Office. For example, you will get fewer page layout options in word processors and fewer transition effects in presentation programs. However, these applications are still professional-grade.
This package includes Docs (word processing), Sheets (spreadsheets), and Slides (presentation). Since they are all located in your browser, any edits will be saved online immediately, so you don't have to worry about backups. If you need to work offline, you can also access these applications (limited features) – no internet connection is required.

It also offers a wide variety of brushes, as well as advanced selection tools, including magic wands.

Another way to think: You might edit the company logo in the former and digital photos in the latter.
In terms of vector graphics, Inkscape provides flexible tools to create lines, shapes, and text. It also provides grouping and hierarchy options, allowing you to manage objects on the canvas. If you need to edit files created in the raster graphics program, you can import and manipulate them. Like GIMP, Inkscape also has free online tutorials to help you get the software up and running.
