PowerPoint has been the default for so long that its file format, .pptx, became the common language of slides. Any alternative has to answer two questions: is it better at the job you need, and does it speak that language well enough for the people you share with? The descriptions below follow each product’s public pages as of this writing; prices and features change, so check before you decide. We make ExpertSlides and say where it fits — and where it does not.
Free alternatives
Google Slides
Free with a Google account, entirely in the browser, with the best real-time collaboration of any tool here: several people edit at once, comments and suggestions sit on the slides, and the link always shows the current version. It opens and exports .pptx files well for ordinary decks; complex animations, SmartArt and some chart types are simplified on the way. Fonts are limited to Google Fonts.
Apple Keynote
Free on Mac, iPhone and iPad, with elegant themes, smooth animations (Magic Move is Keynote’s counterpart to Morph) and excellent typography. It opens and exports PowerPoint files, with some loss in complex animations and in fonts missing on Windows. Collaboration works through iCloud, and Windows users can only use the browser version at icloud.com.
LibreOffice Impress
Free and open source, for Windows, Mac and Linux, and fully offline. It looks and works like an older PowerPoint and opens and saves .pptx. Fidelity with modern PowerPoint files is good for text and shapes, weaker for complex animations and some charts. A sound choice where licences cost too much or data must stay local.
PowerPoint for the web
Often overlooked: Microsoft offers a free browser version of PowerPoint with a Microsoft account. It lacks some desktop features — custom shows, some animation options, embedded fonts — but opens and saves real .pptx files without conversion.
Design-first alternatives
- Canva: huge template library, stock assets and a brand kit across presentations, posts and documents; very easy to learn. Exports to .pptx with font and element conversions. Our Canva presentations guide compares it in detail.
- Prezi: a zooming canvas instead of slides — the talk moves across one large picture. Memorable when the structure suits it, disorienting when it does not; exchange with PowerPoint is limited by the different model.
- Pitch: a collaborative slide tool aimed at teams and start-ups, with templates, analytics on shared decks and a clean editor. Imports and exports PowerPoint files.
- Beautiful.ai: smart slides that lay themselves out, plus an AI generator; consistent output, less free placement. See our Beautiful.ai review.
AI presentation makers
AI presentation makers draft a whole deck from a prompt or a document: structure, text, layout, pictures. They differ in what they produce and where it can go.
- Gamma: cards that can be a presentation, a document or a web page; strong for decks read on screen. Our Gamma alternative page compares it with ExpertSlides.
- Microsoft Copilot in PowerPoint: drafts slides inside PowerPoint from a prompt or a Word document, with a Microsoft 365 Copilot licence. The deck stays a native .pptx in your template. See our page on PowerPoint AI.
- Canva and Beautiful.ai: both have AI generators inside their editors.
- ExpertSlides: designed slide decks from a prompt or documents, freely editable afterwards, exported as native PowerPoint.

How to test file exchange before you switch
The real cost of an alternative is in the files you exchange. Test with one real deck of yours — with a chart, a table, your fonts and a few animations — before a team switches.
Round-trip a deck through an alternativeAny tool
Open your .pptx in the alternative
In Google Slides use File → Import slides or open the file from Drive; in Keynote File → Open; in LibreOffice Impress File → Open.
Opening a .pptx in another presentation tool Check the details
Go slide by slide: fonts, line breaks, chart data, table formatting, animations, speaker notes. Note every slide that changed.
Comparing slides after import Export back to PowerPoint
Google Slides: File → Download → Microsoft PowerPoint (.pptx). Keynote: File → Export To → PowerPoint. Impress: File → Save As with the file type PowerPoint 2007-365 (.pptx), and confirm that format when Impress asks whether to keep it.
Open the result in PowerPoint
On the computer of someone who uses PowerPoint daily, open the file and edit a chart, a table and a heading. If it survives, the alternative will work for your exchange.
How to choose
- You share decks with PowerPoint users daily: stay close to .pptx — PowerPoint for the web, or a tool that writes native PowerPoint.
- You need free and collaborative: Google Slides.
- You work on a Mac and present yourself: Keynote.
- You need offline and open source: LibreOffice Impress.
- You want visual decks fast without design skills: Canva, or an AI maker.
- You want the first draft written for you: an AI presentation maker — then check where its output can go.
What switching really costs
Licence fees are the visible part of the decision. The larger costs are usually elsewhere, and they are worth listing before a team changes tools:
- Existing decks. Years of slides live in .pptx files. Converting the ones you reuse — the company introduction, the product slides, the case studies — takes time, and each needs a check after conversion.
- Templates. A corporate .potx with its masters rarely survives a move intact. Plan to rebuild the template in the new tool’s own system of themes or layouts.
- Habits and skills. Shortcuts, add-ins and the tricks people know by heart do not transfer. A short internal guide and one example deck per common use help more than a training session.
- Partners and clients. If they work in PowerPoint, every exchanged file is a conversion. Agree on PDF for reading and .pptx only where they must edit.
- Data and security. Browser tools store decks on their servers. Check where, under which terms, and whether your organisation allows it for confidential material.
A mixed setup is often the realistic answer: one tool where most decks are made, PowerPoint where files must be exchanged, and PDF for everything that is only read. The test above tells you how much friction the mix will cause.
Designs for this kind of deck
Every design brings its own colours, fonts and layouts to the whole deck.
ExpertSlides as an alternative — and a companion
ExpertSlides is an AI presentation maker in the browser that does not ask you to leave PowerPoint behind. You describe the deck or attach a PDF, a Word file, a spreadsheet or your own .pptx; the AI writes it in a design from the gallery; you edit freely, by hand or with plain-language instructions; and you present from the browser or share a Web link.
When the deck has to go to PowerPoint users, the export (Pro and Business) writes native objects: text boxes, shapes, tables, charts with their data, transitions and animations, in the deck’s fonts. The same file is what the Google Slides, Canva and Figma targets of the export hand you to import there. Every plan exports PDF; on Free the PDF carries the ExpertSlides mark. A free account lets you try it on a real deck before you decide.
