10 Best Free Presentation Tools for Teachers in 2025

The days of boring PowerPoint slides are long gone. Today's teachers have access to a remarkable range of free, browser-based presentation tools that make lessons more engaging, interactive and memorable. Here are the ten best — all usable in any browser with no software to install.

1. Canva

Canva is the go-to tool for teachers who want professional-looking slides without a design background. Its drag-and-drop editor, thousands of educational templates and free image library make it the most accessible option on this list. The free tier is generous; the Canva for Education plan is completely free for verified teachers.

2. Google Slides

Part of Google Workspace for Education, Google Slides is free, collaborative and integrates seamlessly with Google Classroom. Students can present, comment and co-edit in real time — ideal for group projects and hybrid lessons.

3. Genially

Genially specialises in interactive content. Presentations can include clickable hotspots, embedded quizzes, animations and even escape-room-style activities. The free plan allows unlimited interactive creations — rare for a tool this powerful.

4. Prezi

Prezi replaces the linear slide format with a zoomable canvas. Instead of clicking through slides, you zoom into different areas of a large visual map — an approach that works especially well for showing how concepts connect. The free plan is sufficient for most classroom uses.

5. Slides.com

Slides.com is built on the open-source Reveal.js framework and produces sleek, modern presentations that run in any browser. Slides created on the free plan are public, but the visual editor is among the cleanest available.

6. Emaze

Emaze offers cinematic 3D transition effects and themed templates. The free tier lets you create two presentations with basic features — enough to try before committing.

7. Visme

Visme blends presentations, infographics and data visualisations in one tool. Teachers covering data literacy or STEM subjects will appreciate the built-in chart editor and diagram library. The free plan includes five projects.

8. Mentimeter

Mentimeter turns presentations into live Q&A sessions, polls and word clouds. Students respond on their phones in real time, and results appear instantly on the projected screen. Free for up to two slides per presentation.

9. Gamma

Gamma uses AI to generate a complete presentation from a prompt or outline. Teachers can describe the lesson topic and get a polished deck in under a minute — then customise it. Free for up to ten AI generations.

10. Nearpod

Nearpod combines presentation delivery with real-time formative assessment. Teachers send slides to every student's device and can launch polls, open-ended questions and virtual field trips mid-lesson. The free Silver plan covers most classroom needs.
