Mozilla Firefox
Mozilla Firefox allows you to navigate, organize tabs and manage your browsing data on Windows.
Which open source software to download for Windows?
Choosing open source software means paying attention to its license as much as its functions. Access to the code and the rights granted to study, modify or redistribute it distinguish these programs from a simple proprietary free offer. However, you do not need to program to use them: the projects in this selection offer distributions intended for users of Windows. They cover several activities, from browsing to creating images, including documents and media. The license does not guarantee a particular interface or perfect compatibility with all files. So start with your daily need, check the packages available, then look at the formats and terms that matter to your personal or business environment.

How to choose
- Check that the license concerns the chosen program and its current edition, without deducing the status of the software from the displayed price alone.
- Choose a package distributed by the project or a channel it specifies, then check the Windows architecture and the requirements of the version chosen.
- Evaluate the functions with a current project and its exchange files; an open source license is not enough to ensure compatibility with each format.
- Consider separate extensions, content and related services, which may use other licenses or have their own access terms.
- Have a method for updating and retrieving your settings, especially if multiple people use the same formats and procedures.
16 programs
158.0
Mozilla Firefox provides an open source browser for accessing web sites and services. You can use it without modifying its code. Added extensions and consulted services maintain their own conditions. Check the requirements of the current version and configure the profile according to your needs before deploying it on several workstations.
7-Zip
7-Zip creates 7z and ZIP archives, extracts RAR files and protects archived content with a password.
7-Zip provides archiving functions with code accessible under the licenses indicated by the project. For simple use, choose the Windows package corresponding to your architecture. If you plan to redistribute or integrate, review the terms of the affected components. Format support must also match the files exchanged with your recipients.
VLC media player
VLC media player plays your audio and video files, discs and compatible network streams.
VLC media player is an open source media player usable from the project's Windows packages. It is used to view compatible files and streams. Its status does not give rights to the content read and does not remove any protections. Test the usual tracks and subtitles before setting your file associations.
LibreOffice
LibreOffice combines word processing, spreadsheets and presentations in a free office suite.
LibreOffice combines an open source license with office production tools. It can be used to create texts, tables and presentations in a Windows compatible environment. Check document exchanges with other suites used around you. The status of the software does not guarantee identical reproduction of all macros or functions specific to external formats.
GIMP
GIMP edits your photos and composes images with layers, masks and selection tools.
GIMP enables image editing and composition in an open source project. Official packages avoid compiling the program for common use. Check extensions and added resources separately. For shared work, distinguish the editable project file from the exported image intended for distribution or printing.
Krita
Krita offers brushes, layers and stop-motion animation for digital drawing.
Krita offers an open source environment oriented towards digital drawing and painting. You can start with Windows distributions without changing the code. Try your brushes, your tablet and the dimensions of your projects. The licenses of the resources you add still need to be checked separately when you distribute content or prepare a shared environment.
OBS Studio
OBS Studio composes scenes to record your screen and stream live video.
OBS Studio covers recording and streaming audio and video sources with open source software. Practical requirements depend on the chosen scene and encoding. Check additional modules as well as the conditions of external services. The program does not automatically provide permissions for images, music or platforms used during a broadcast.
Notepad++
Notepad++ edits text and code with tabs, advanced search and syntax highlighting.
Notepad++ provides access to an open source text and code editor for Windows. It is suitable for technical files without office layout. Extensions must be chosen and monitored according to their role. When sharing an environment, also note the encoding and expected settings so that the files remain usable by other tools.
calibre
calibre organizes your digital book library, converts formats and supports reading.
calibre organizes digital books and their metadata in an open source project. Its conversion functions depend on formats and access to content. The protections applied to books do not disappear thanks to the program license. Test the resulting files on the intended reading device and keep the originals in your library.
BleachBit
BleachBit cleans temporary files and traces left by your Windows applications.
BleachBit offers data category cleaning with open code. Its license does not change the scope of a local deletion: review the options and preview before taking action. It is suitable for an identified cleaning purpose. Access to sources may be of interest to an organization, but does not exempt you from understanding the files that will be affected.
SumatraPDF
SumatraPDF opens your PDFs, digital books and comics in a reader for Windows.
SumatraPDF is an open source reader for several document types, including PDFs. It can meet a consultation need without the functions of a complete editor. Available packages vary depending on the Windows architecture. Check the compatibility of the chosen package and try your usual documents, especially scans or particularly large files.
PeaZip
PeaZip creates and extracts archives, with tools to organize files and prepare for sharing.
PeaZip offers an open source archiver to organize, create and extract sets of files on Windows. It is suitable if you are looking for an interface combining archive and file management operations. Check the creation formats separately from the extraction formats and test the archive received by your correspondent. An open license does not guarantee significant compression of already compressed media.
ScreenToGif
ScreenToGif records an area of the screen and allows you to modify images before an animated export.
ScreenToGif brings an animated capture and frame editor in an open source project for Windows. It is suitable for short tutorials, command demonstrations, and explanations to insert into a document. Choose a focused capture area, then remove unnecessary pauses before exporting. This workflow does not automatically replace scene management and live streaming of OBS Studio.
PDF Arranger
PDF Arranger assembles, separates and rearranges pages of PDF documents in a visual interface.
PDF Arranger meets a specific document task: joining, separating, reordering and rotating pages of PDF files. Its thumbnail interface helps assemble documents without modifying the text of the pages. The open source project offers a Windows package; choose the official package corresponding to your system. Keep the original documents and check the page order in a reader after export.
Notepad3
Notepad3 edits plain text and code with syntax highlighting, search tools and encoding options.
Notepad3 adds an open source plain text editor for technical notes, configuration files and code. Its search, syntax highlighting and encoding tools make targeted edits on Windows easy. It is suitable when you want to preserve a textual structure rather than compose a printed page. Keep a copy before an encoding conversion and check the file in the program that will use it.
LosslessCut
LosslessCut prepares video and audio cuts by favoring the copying of streams without re-encoding.
LosslessCut offers an open source tool for cutting media by copying their streams when the format allows it. This approach is suitable for preparing snippets without applying new compression to the entire video. Official downloads and some stores may follow different pricing conditions. Check the chosen channel, keyframes and retained tracks; the software does not replace complex editing with effects.
Understanding the difference between license and price
A program can be free without providing access to its source code or allowing its modification. Conversely, an open source license can allow paid distribution or commercial services around the software. Here, the common point concerns the status of the selected projects, not a promise that every associated service is free. This distinction becomes useful when you want to adapt a tool or redistribute it within an organization. Then read the applicable license requirements instead of just the download button. For a search focused on free offers, “Free software per use” also includes proprietary programs and explains why these two criteria do not form a single category.
Use the distributions provided for your computer
Access to the source code does not require you to compile the program. Selected projects make Windows packages available, but supported architectures and versions may change. Compare the proposed download to your system before relying on the age or reputation of the project. Open source software is not necessarily suitable for an old computer: OBS Studio and graphic tools also depend on the load of the project and the hardware used. The official download page remains the starting point for choosing a distributed version. Avoid confusing the instructions intended for developers with the installation path intended for everyday use of the program.
Distinguish open formats from project files
Program licensing and document format are two separate topics. An open source tool can open external formats without duplicating all functions, while its own project files may require compatible software. With LibreOffice, GIMP or Krita, check what your correspondents should receive: an editable document, a final export or both. calibre raises another question when a book has digital restrictions; access to the source code does not remove content restrictions. So define your exchanges before changing your work format. You will be able to choose the relevant functions while retaining the elements necessary to resume a project at a later stage.
Examine the components around the application
Extensions and services do not automatically take over the conditions of the main program. A Firefox extension, a module added to an editor, or a streaming service used with OBS Studio may have its own rules. Choose these items based on their purpose and where they come from, then check what they add to your environment. The same attention goes for the fonts, images and other content used in your productions. The open source status of the software does not give additional rights to these resources. This distinction allows you to explain precisely what you are installing and what you can share, without assigning the entire workflow a single blanket license.
Choose according to the activity then organize the follow-up
For media playback, VLC serves a different task than capturing with OBS Studio. For documents, SumatraPDF, Notepad++ and LibreOffice do not cover the same work. Start with these functions, then choose the licenses and formats compatible with your context. The “Productivity” section helps to locate document tasks, while “Replace paid software” prepares the replacement of a paid tool. Keep a list of download sources and important settings. You will thus be able to follow updates and reproduce your environment without transforming the adoption of open source software into a technical commitment broader than your initial needs or your means of maintenance.
Frequently asked questions
Does open source mean I have to know how to program?
No. The programs in this selection have distributions intended for users of Windows. You can install and use them without changing their code. Access to sources adds possibilities for people who need them, but is not a required step to browse, create a document or play a video.
Can open source software be sold?
Yes, depending on the rights and obligations of its license, a distribution or an associated service may be subject to payment. Open source status describes permissions related to the code, not a general prohibition of any commercial activity. Check the download channel and the services offered before comparing the cost of several offers.
Will all my files be readable in these programs?
The license does not guarantee support for every format or function. Test files representative of your work, then check the results after editing and exporting. Macros, layouts, protected content, and project formats may require attention even when the document opens.
Can this software be installed in a company?
You need to check the program license, added components and your organization's policies. The need may also include support, update procedures and formats imposed by partners. The existence of an open source project does not replace this concrete evaluation of uses and maintenance.
