What free software do you think everyone should know about?

Some free software is useful because it replaces an expensive program. Other software is worth knowing because it solves a problem you may not even realize you have. The best examples are tools that are reliable, broadly useful, and capable enough that you can continue using them for years.

A good starting point is LibreOffice. It is a free and open-source office suite containing Writer for documents, Calc for spreadsheets, Impress for presentations, Draw for diagrams, Base for databases, and Math for formulas. It can be used at no cost for personal or business purposes.

But an especially useful collection of free software goes far beyond office work.

LibreOffice: A Complete Office Suite

Many people assume that creating documents, spreadsheets, and presentations requires a paid office subscription.

LibreOffice is a useful alternative.

Its different applications cover many everyday tasks. Writer handles documents, Calc handles spreadsheets, and Impress handles presentations. Draw can be used for diagrams and other visual documents, while Base provides database functionality.

It is particularly useful for students, freelancers, small businesses, organizations, and anyone who needs conventional office tools without wanting to pay for a subscription.

Another advantage is that LibreOffice is open source. That means its development is not based solely on giving users access to a proprietary application; the underlying software is available under an open-source license.

The main consideration is compatibility. If you regularly exchange complex documents with people using another office suite, formatting can sometimes require checking before you send the final file.

VLC: A Media Player Worth Having

A good media player is one of those programs you may not appreciate until you encounter a video or audio file that your usual application cannot handle properly.

VLC has become a popular choice because it is designed as a versatile media player rather than being tied to a particular operating system’s default media experience.

That makes it useful when you have different types of media files, external drives containing old videos, downloaded recordings, or media from different sources.

The broader lesson is useful: sometimes a specialized free tool can solve a problem more effectively than trying to force a default application to do everything.

7-Zip: Essential for Compressed Files

Compressed files are common when downloading software, transferring multiple documents, backing up files, or sharing large collections of files.

7-Zip is a free, open-source file archiver that can create and extract compressed archives.

Knowing how archive files work is useful even if you rarely think about file compression.

For example, instead of sending dozens of individual documents, you can place them into one archive. This makes organization and transfer easier.

It is also useful to understand that an archive is not necessarily a backup. Compressing important files does not protect them from drive failure or accidental deletion. A proper backup strategy is still necessary.

GIMP: Powerful Image Editing Without a Paid Subscription

GIMP is one of the most useful free programs for people who work with images.

It provides tools for photo editing, image composition, graphic design, illustration, and other forms of image manipulation. It is available across major desktop operating systems and is free and open source.

Someone who needs to resize images, remove backgrounds, adjust photographs, create graphics, or edit existing artwork can use GIMP without purchasing a commercial image editor.

It is also capable of more advanced work than many beginners initially expect.

The trade-off is that powerful software can have a learning curve. A beginner may find a simpler image editor easier for quick tasks, while GIMP becomes more valuable as their editing needs become more sophisticated.

Inkscape: Useful for Vector Graphics

Raster image editors and vector graphics programs solve different problems.

A raster image is made from pixels, while vector graphics use mathematical paths that can be scaled without becoming pixelated in the same way.

That distinction matters for things such as logos, diagrams, icons, illustrations, and certain types of print design.

Inkscape is a free and open-source vector graphics editor that can therefore be useful for people who need to create or modify scalable artwork.

Understanding the difference between raster and vector graphics is itself a useful digital skill.

Audacity: Helpful for Audio Editing

Audio editing can seem like something only musicians or professional studios need.

In reality, many people eventually need to trim recordings, clean up audio, edit interviews, create voiceovers, or work with other sound files.

Audacity is a well-known free and open-source audio editor and recorder.

For someone beginning a podcast, editing a school project, preparing a voice recording, or experimenting with audio production, it can provide a substantial set of capabilities without requiring expensive professional software.

OBS Studio: More Than a Screen Recorder

OBS Studio is especially useful for recording and live production.

It can capture a screen, combine different visual sources, manage scenes, and record or stream content.

Even if you have no interest in live streaming, screen recording can be useful for demonstrations, tutorials, software walkthroughs, presentations, and troubleshooting.

The important thing is to use recording tools responsibly, particularly when other people’s voices, faces, or private information are involved.

Krita: A Strong Choice for Digital Art

People interested in digital painting and illustration may find Krita particularly useful.

Unlike software designed primarily around photo correction, digital-art applications are built around drawing and painting workflows.

Krita provides tools intended for artists working with digital illustrations, paintings, comics, and related projects.

It demonstrates an important advantage of the free-software ecosystem: you can find capable tools built specifically for particular creative activities rather than relying on one expensive program for everything.

Blender: A Much Bigger Tool Than Many People Expect

Blender is another example of free software that can perform professional-level tasks.

It is a 3D creation platform used for areas such as modeling, animation, rendering, simulation, and visual effects.

It is not a simple beginner application. Learning it can take considerable time because 3D production involves many different concepts.

But that is precisely why it is worth knowing about.

Someone interested in animation, game development, 3D design, visual effects, architecture, or digital art can begin learning powerful concepts without first purchasing an expensive 3D package.

Shotcut and Other Free Video Editors

Video editing is now useful for far more than professional filmmakers.

Students create presentations.

Businesses create promotional videos.

Teachers create lessons.

Creators make educational content.

Organizations publish interviews and demonstrations.

A capable free video editor can therefore be valuable even if you never intend to become a professional filmmaker.

The best choice depends on your computer, experience, and editing requirements, so it is worth evaluating the features you actually need rather than assuming the most complicated application is automatically the best.

Firefox: A Reminder That You Have Browser Choices

A web browser is one of the most important pieces of software on a computer because it is effectively the gateway to much of the internet.

Firefox is a major example of a browser developed outside the dominant commercial browser ecosystems.

Knowing that alternatives exist is useful because browsers differ in their approaches to privacy, customization, compatibility, performance, and ecosystem integration.

The larger lesson is not that everyone must use one particular browser.

It is that users should understand that the default application is not necessarily their only reasonable option.

KeePassXC: Understanding Password Management

Password management is another area where free software can be extremely useful.

People often reuse passwords because remembering many unique passwords is difficult. That can create unnecessary security risks if one account is compromised and the same password is used elsewhere.

A password manager can help organize unique credentials so that users do not have to memorize every password individually.

KeePassXC is one example of free and open-source password-management software designed for desktop use.

Whatever password manager someone chooses, the important concept is understanding why unique, strong credentials and good account security practices matter.

Free Software Does Not Mean “No Value”

One common misunderstanding is that free software must be inferior to paid software.

That is not necessarily true.

There are different reasons software can be free.

Some projects are open source and developed by communities.

Some organizations provide free versions alongside paid products.

Some projects are supported by donations.

Others use different business models.

The price alone tells you very little about quality.

The more useful questions are:

Does it solve my problem?

Is it maintained?

Is it compatible with my system?

Does it have the features I need?

Can I trust the source I am downloading it from?

Free Software Still Needs to Be Downloaded Carefully

One of the biggest mistakes people make is assuming that anything labeled “free download” is safe.

Software should preferably be obtained from the developer’s official website or another trustworthy distribution channel.

Be cautious with websites that bundle unrelated programs, modify installers, or make it difficult to understand what you are actually downloading.

The safest free application is not particularly useful if someone installs a malicious imitation of it.

It is also worth checking whether an application is still actively maintained. Software can become outdated, and an abandoned project may not be appropriate for important tasks.

Learn the Difference Between Free and Open Source

The terms are related but not identical.

“Free” can simply mean that you do not have to pay money.

“Open source” generally refers to software whose source code is made available under terms that allow particular forms of use, study, modification, and redistribution.

LibreOffice, GIMP, and many other projects demonstrate how open-source development can create sophisticated software that people can use without paying a traditional license fee.

Understanding this distinction gives people a better idea of what they are actually receiving.

Do Not Install Everything Just Because It Is Free

Having access to hundreds of free applications does not mean you need hundreds of applications.

Too many programs can create clutter, consume storage, generate unnecessary notifications, or introduce maintenance and security concerns.

A better approach is to install software when you have a genuine need.

For example, someone might need:

• An office suite for documents and spreadsheets
• A media player for video and audio
• An archive utility for compressed files
• An image editor for graphics
• A password manager for credentials
• A browser that fits their preferences

Someone else may never need 3D modeling, audio production, or professional image editing.

The best software collection is the one that solves your actual problems.

Free Software Can Make Technology More Accessible

One of the most valuable things about free software is that it can reduce the cost of entering a particular field.

Someone interested in graphic design does not necessarily need to purchase expensive professional software before learning the fundamentals.

Someone interested in video production can begin learning editing concepts with free tools.

Someone interested in office administration can practice documents and spreadsheets without immediately purchasing a commercial office suite.

Someone interested in programming can access an enormous ecosystem of free development tools.

This makes experimentation easier.

You can discover whether you genuinely enjoy something before making a significant financial commitment.

The Best Software Is the One That Helps You Do Something

It is easy to become interested in software for its feature list.

But features are not the same as usefulness.

A program with hundreds of functions may be less valuable to you than a simple tool that solves one recurring problem quickly.

For example, if you only need to resize an image occasionally, you may not need an advanced image-production workflow.

If you regularly work with spreadsheets, however, learning a capable office suite could save you considerable time.

The value of software depends on the problems it helps you solve.

A Useful Starter Collection

If someone were starting from scratch, a sensible free-software toolkit could include tools from several categories:

Office work: LibreOffice

Media playback: VLC

File compression: 7-Zip

Image editing: GIMP

Vector graphics: Inkscape

Digital art: Krita

Audio editing: Audacity

3D creation: Blender

Video production: OBS Studio and a suitable free editor

Password management: KeePassXC

You do not need to install all of them.

The point is to know that capable alternatives exist when a particular need arises.

Free Software Is Also Worth Learning About for the Skills It Teaches

A useful program can teach more than the task you initially wanted to accomplish.

Learning spreadsheets can teach you how to organize and analyze information.

Learning image editing can teach you about layers, resolution, formats, and visual composition.

Learning video editing can teach you about timelines, codecs, audio, and storytelling.

Learning 3D software can introduce modeling, lighting, animation, and rendering.

Learning open-source software can also expose you to a different way of thinking about technology, where users can inspect, modify, and contribute to software rather than simply consuming a finished commercial product.

The Bigger Lesson

You do not need to know every free application available.

What is more valuable is developing the habit of asking:

Is there already a good tool for this problem?

Before paying for expensive software, investigate whether a capable free alternative exists.

Before installing a random application, check who develops it and whether it is maintained.

Before choosing the most complicated tool, consider what you actually need.

And before dismissing free software as inferior, look at what the software can genuinely do.

Some of the most useful programs available today are free because developers, communities, foundations, and organizations have found ways to build and maintain them without charging every user a traditional software license.

Knowing a few of these tools can save money, expand what you can do with your computer, and make it easier to explore new skills.

The most valuable free software is therefore not necessarily the program with the longest feature list. It is the software you know well enough to reach for when you have a real problem to solve.
