Essential free software for school and college students

Permanent catalog page. Updated September 3, 2026. Other packs: kits.

Almost every student needs the same things: write text, build a spreadsheet or slides, read and annotate PDFs, study for exams, manage deadlines, and — in college — cite sources without rebuilding the bibliography by hand. That is often linked to paid packages or pirate downloads. In practice, the most common school and college tasks already have official free programs, many of them open source.

This guide starts with the office suite — what almost everyone uses first — then covers other everyday routines. If you have an institutional email, you may get Microsoft 365 Education or Google Workspace from school; even then, it helps to have offline and open-source options on your computer. Links point to official sites. In the SwitchToFree catalog, the most useful sections here are Productivity, Study & research, and Organization.

Office suites

Essays, reports, theses, grade sheets, presentation slides, and group work almost always go through a word processor, a spreadsheet, and a slide app. That is the foundation: without it, the rest of the academic kit is incomplete.

LibreOffice

LibreOffice is the most widely used open-source desktop suite: Writer, Calc, and Impress cover Word, Excel, and PowerPoint with no subscription and no required account. It works offline on Windows, macOS, and Linux, opens and saves DOCX, XLSX, and PPTX, and exports to PDF. For shared machines, unreliable internet, or avoiding the school's cloud, it is the most direct choice.

Google Docs, Sheets, and Slides

With a free Google account, the Docs, Sheets, and Slides trio shines for group work: several people in one file, teacher comments, and phone access. Many schools already use Google Classroom; the natural flow is write in Docs and turn in PDF or DOCX. Offline use in Chrome is possible after enabling Drive offline mode.

Microsoft 365 on the web (and Education)

Microsoft 365 for the web offers Word, Excel, and PowerPoint in the browser with a free Microsoft account. If your institution qualifies, a school email may unlock the Education package with apps and storage — check your school or university portal. The upside is maximum compatibility with what teachers and classmates still ask for in Office format.

ONLYOFFICE Desktop

ONLYOFFICE Desktop Editors combines documents, spreadsheets, presentations, and PDF in an interface close to the modern Office ribbon. It is open source, free for personal use, and strong with DOCX/XLSX/PPTX — useful when the priority is “looks like Word” without paying for Microsoft 365.

FreeOffice and WPS Office also have free versions (freemium, closed source). The full suite comparison is in Free alternatives to Microsoft Office and Microsoft 365.

Read, annotate, and build PDFs

Handouts, papers, slides from teachers, and files to submit on the platform: PDF is the default school format. Reading well, marking text, and merging pages before the deadline saves stress the night before.

SumatraPDF and Okular

SumatraPDF (Windows) is light and fast for large handouts without freezing the machine. Okular (strong on Linux, also elsewhere) adds annotations, highlights, and forms. Both are open source and replace Acrobat Reader everyday use.

Xournal++

Xournal++ is a favorite for handwriting on PDFs — pen, tablet, or stylus laptop. You can underline, sketch formulas, and export again as PDF. In student communities with tablets, it often appears alongside paid digital notebook apps.

PDF24 and PDFsam

To merge chapters, split a file, or compress before uploading to a learning platform, PDF24 and PDFsam Basic work without a subscription. PDF24 also has browser tools; PDFsam is open source and focuses on merging and splitting pages.

If you read many papers and want fast in-text search, look at Sioyek, an academic reader listed in the study catalog.

Notes and knowledge organization

Class notes, weekly summaries, and ideas scattered across loose files need a central place. The goal is not a perfect “second brain”: it is finding Tuesday's notes when the exam arrives.

Obsidian

Obsidian stores Markdown notes on your disk, with links between subjects and folders by course. Individual use is free. In college and graduate forums, it often appears with Zotero and Anki: note in class, connect concepts, review later. There is a learning curve, but the files stay yours — without locking content behind a paid plan.

Joplin

Joplin is open source end to end, with more straightforward sync (including self-hosted options) and apps for desktop and phone. People who want the same digital notebook spirit with fewer plugins and more “install and use” often prefer Joplin over Obsidian.

Freeplane

Freeplane builds mind maps to review material, prepare oral exams, or see a chapter's structure. It is open source and light enough for one map per course the night before the test.

Many students also use Notion on the free or education plan; here the focus stays on catalog options with files under your control.

Memorize for exams

Entrance exams, medical school tests, languages, physics formulas, or history dates: anything that must return on exam day benefits from spaced repetition — review just before you forget, not only by rereading the summary.

Anki

Anki is the open-source standard for spaced-repetition flashcards. Free desktop on Windows, macOS, and Linux; AnkiWeb sync is free; on mobile, Android is free and iOS has a paid app from the project team. Shared decks and your own cards cover everything from vocabulary to anatomy. A daily 15–20 minute habit usually beats a cram session the night before.

The catalog also lists Mnemosyne and RemNote if you want other SRS and note approaches.

References and research

In college — and already in high school for projects, science fairs, or papers — bibliographies eat time and invite mistakes. A reference manager keeps the PDF, citation, and style (APA, MLA, Chicago, Vancouver) in one place.

Zotero

Zotero is open source, with a browser connector to save an article or page in one click, folders per assignment, and plugins for Word, LibreOffice, and Google Docs. The bibliography builds itself from sources cited in the text. Project cloud storage has a free quota; large PDFs can stay on disk only. In academic communities, Zotero + Obsidian (or just Zotero + an office suite) is one of the most cited combos.

JabRef

JabRef shines if your workflow is already BibTeX/LaTeX. For most courses that turn in DOCX or PDF from Writer/Word, Zotero is enough. LaTeX writers will find Overleaf, TeXstudio, and LyX in the catalog's Study & research section — outside the “almost everyone” scope, but useful in STEM and graduate work.

Grammar and proofreading

Before turning in an essay or thesis, a second pass for spelling and style reduces points lost to carelessness.

LanguageTool

LanguageTool checks grammar and style in the browser, LibreOffice, and extensions for many languages including English. The free tier covers typical school use; LibreOffice Writer also has its own spell checker. It is the catalog's listed alternative to Grammarly and premium proofreaders.

Deadlines, focus, and routine

Overlapping assignments, exams in the same week, and long study nights need a clear list and breaks — not just more coffee.

Super Productivity

Super Productivity is an open-source task manager with lists, kanban, and a focus on personal productivity. You can keep a board per course or semester without paying for Trello Premium.

Pomatez and Stretchly

Pomatez applies the pomodoro technique (focus blocks with breaks). Stretchly reminds you to pause and stretch — a small detail that keeps a study marathon from ending only with a stiff neck. Both are in Study in the catalog.

Math and numbers

In high school almost everyone deals with graphs and geometry; in college, many still need a serious calculator or basic statistics.

GeoGebra and Desmos

GeoGebra (open source) and Desmos (free on the web) cover functions, dynamic geometry, and visualization for homework and exams. They work well in the browser and on phones.

Qalculate!

Qalculate! is a scientific open-source calculator that understands long expressions, units, and conversions — more powerful than the system calculator for physics, chemistry, and engineering.

If a course needs friendly statistical analysis, jamovi and JASP replace much of what students look for in paid SPSS.

How to build a minimal kit

You do not need twenty programs. A base pack of five coverages handles most of the semester:

1. LibreOffice or Google Docs — write documents, build spreadsheets, and present.
2. SumatraPDF (or Okular) and, if you use a pen, Xournal++ — read and annotate PDF.
3. Obsidian or Joplin — class notes and summaries.
4. Anki — memorization with spaced repetition.
5. Zotero — references from advanced high school onward and in college.

Typical flow: note in class → turn key points into Anki cards → write the paper in LibreOffice or Docs → cite with Zotero → proofread in LanguageTool → export or merge PDF and submit.

By major (brief)

Some majors need extra tools. In STEM and engineering, GNU Octave and editors in Development (such as VSCodium) appear early. In design and arts, GIMP, Inkscape, and Krita are in Design. The rest of this page intentionally stays with what almost everyone needs — the catalog covers niches without turning the basic kit into an endless list.

Conclusion

An office suite, PDF reader, notes, Anki, Zotero, and a bit of organization cover most of school and college life — with official downloads and no cracks. Explore the catalog's Study & research section and, for Word/Excel/PowerPoint without paying, the guide to free alternatives to Office. For files and cloud quota: alternatives to Drive, OneDrive, and Dropbox.
