Convert .pptx PowerPoint presentations to PDF in your browser. Extracts slide titles and bullet text — text-only, no shapes or images. Free, no upload.
Convert modern PowerPoint presentations (.pptx) to a clean, text-focused PDF entirely in your browser. The tool unzips the .pptx (PowerPoint files are ZIP archives), parses each slide's XML to extract titles and body text, and renders one slide per landscape-A4 PDF page using <strong>pdf-lib</strong>. <strong>Text-only conversion</strong> — slide content is captured as title + bullets, but shapes, images, charts, animations, transitions, slide masters, custom themes, and any visual styling are not rendered. For visually-faithful output, PowerPoint's built-in "Save as PDF" or LibreOffice Impress remain the right choice. The advantage of this tool: your presentation never leaves your device, and the output is small, searchable, and easy to skim — perfect for meeting notes, handouts, agenda summaries, or sharing the content of a slide deck without exposing the full file.
The conversion runs in three stages, all inside your browser tab:
ppt/slides/slide1.xml, slide2.xml, etc.<a:t> elements (Office Open XML "text" tags), grouped into paragraphs by <a:p> tags. We extract every text fragment, group by paragraph, and treat the first non-empty paragraph as the title with the rest as body bullets.Total time on a modern laptop: 1-3 seconds for a 20-slide deck; 10-15 seconds for a 200-slide deck. The bottleneck is XML parsing for very large decks; rendering is fast.
| Element | Status | Notes |
|---|---|---|
| Slide titles | ✅ Full | Detected as the first non-empty paragraph |
| Bullet text | ✅ Full | All visible text on each slide |
| Slide numbers | ✅ Optional | Toggle in the UI |
| Speaker notes | ❌ Dropped | Not extracted in current version |
| Images and photos | ❌ Dropped | Use PowerPoint's native export |
| Charts and graphs | ❌ Dropped | Chart data isn't captured |
| Shapes, lines, arrows | ❌ Dropped | Only text inside shapes is kept |
| Tables on slides | ⚠️ Flattened | Cell text becomes bullet lines |
| Animations / transitions | ❌ N/A | PDF can't express animation |
| Slide masters / themes | ❌ Dropped | Default Helvetica throughout |
| Custom fonts | ❌ Substituted | Helvetica only |
| Embedded audio / video | ❌ Dropped | PDF can't carry media |
If you need any of the missing elements, the output won't serve your purpose — use PowerPoint or LibreOffice Impress instead.
Most people reach for PowerPoint→PDF expecting a visual export, but several real workflows are actually better served by a text-only output:
PowerPoint decks frequently contain some of an organisation's most sensitive material — board presentations, financial roadmaps, sales pipelines, M&A briefings, strategy documents, internal HR slides. Many "free PPT to PDF" sites operate as upload-then-convert services where the deck transits a server you do not control. For a presentation that names specific clients, financials, or internal plans, that single upload step can be a real problem.
This tool processes the .pptx entirely in your browser. JSZip unzips locally, DOMParser parses locally, pdf-lib renders locally, the PDF downloads from your browser to your downloads folder. Open DevTools, go to Network, run a conversion, and confirm: zero outbound requests for your file. The trade-off is fidelity — you get text-only output instead of visual fidelity — but for sensitive content where you cannot upload to a stranger's server, this is the only safe free option on the open web.
Browser-based PowerPoint conversion is the hardest of the Office formats to render faithfully. The .pptx format describes slides as a complex hierarchy of shapes, layouts, themes, masters, and animations — reconstructing that visual hierarchy without the PowerPoint or LibreOffice rendering engines is not practical client-side. This tool extracts the text content and produces a clean text-only PDF; for visual fidelity, use PowerPoint or LibreOffice Impress.
Three cases where text-only PowerPoint→PDF is the right choice. (1) Meeting handouts: people want to read what was said, not stare at the slide visuals. A text-only PDF is easier to skim and prints in 5x less paper. (2) Sharing slide content via email: if your audience just needs the talking points, a small text PDF is easier to attach than a 30 MB PowerPoint with embedded videos. (3) Search and archive: text-only output is fully searchable and indexable, perfect for archiving meeting decks. (4) Accessibility: screen readers handle plain-text PDFs vastly better than visual PowerPoint exports.
The legacy .ppt format is a binary blob from the 1990s with no open specification — parsing it requires reverse-engineered libraries that are unreliable in browsers. The modern .pptx format (introduced with Office 2007) is a ZIP archive of XML files with a published spec, making it parseable with standard browser tools. To convert a .ppt, open it in PowerPoint or LibreOffice and re-save as .pptx, then convert.
Two reliable options: (1) Open the .pptx in PowerPoint itself and use File → Save As → PDF. PowerPoint's native PDF export is the gold standard — it produces pixel-perfect output with all shapes, images, and themes preserved. (2) Open the .pptx in LibreOffice Impress (free, cross-platform) and use File → Export → PDF. LibreOffice produces output close to PowerPoint's. Both options run on your device, so the file does not leave you. Use this tool only when you specifically want text-only output.
No. The .pptx is unzipped in your browser by JSZip, the slide XMLs are parsed by the browser's built-in DOMParser, and the PDF is built locally by pdf-lib. Open your network inspector while converting — there are no upload requests. Your presentation never leaves your device.
Up to 100 MB. The conversion runs in browser memory; very large presentations (200+ MB) may exceed limits on phones. Note that .pptx files are often dominated by embedded images and videos; the actual slide-text content is usually only a small fraction of the file size, so the output PDF is typically much smaller than the input.
No, speaker notes are not extracted in the current version. Only the visible slide text (titles and body bullets) is rendered. If you need speaker notes, open the .pptx in PowerPoint or LibreOffice and use File → Export with notes view enabled.
