PPT to PDF
Online

What this does

Converts a PowerPoint file (.pptx) into a PDF, in your browser. Each slide becomes one page. Fonts and layout look the same as on screen. No software install, no account, and the file never leaves your device — useful when the deck contains client data, an unfinished thesis, or anything else you'd rather not feed to a third-party converter.

Who actually needs this

Three situations come up most often. Students and faculty submitting work to a learning-management system: Canvas, Blackboard, Brightspace, and Moodle all accept .pptx but PDF is what graders open without opening PowerPoint, and many course portals require PDF for the version that goes into the gradebook of record. Conference speakers and authors uploading slides alongside a paper or abstract — IEEE, ASEE, ACM, and the smaller society and university conferences all standardize their proceedings collections on PDF, not editable Office files. And anyone sharing a deck on LinkedIn as a "document post," where the platform requires PDF and turns it into a swipeable card.

Outside those, the everyday case: emailing a deck to someone who might not have PowerPoint or Keynote, or printing handouts before a meeting. PDF opens natively on every desktop and mobile OS — there's no compatibility step.

What you drop in

The tool reads .pptx — the format PowerPoint, Keynote, LibreOffice Impress, Google Slides, and Canva have used since 2007. Older .ppt (the binary format from 2003 and earlier) isn't supported: open the file in PowerPoint or Keynote and re-save it as .pptx first, which takes a few seconds.

From Google Slides: File → Download → Microsoft PowerPoint (.pptx). From Canva: Share → Download → Microsoft PowerPoint. From Keynote: File → Export To → PowerPoint. The exported file drops in here directly.

What the PDF looks like

One page per slide, in the same aspect ratio as the original (16:9 widescreen by default, or 4:3 standard). Text, images, fills, lines, colours — all in place. The output is a bit larger than the .pptx because each slide is rasterized at high resolution: a 15-slide deck typically lands around 3–8 MB. If you need to attach it to an email with a 5 MB cap or upload it to a form with a strict size limit, run the result through compress-pdf.

What this PDF can't do

The text isn't selectable, copyable, or searchable. Each PDF page is effectively a picture of the slide — that's the trade-off for keeping everything in the browser without a server-side Office runtime. For viewing, printing, posting on LinkedIn, or submitting to a course system, that's fine. If you need searchable text for archiving, accessibility (so a screen reader can read the slides), citation extraction, or copying paragraphs out — use the export inside the program where you made the slides: File → Export → Create PDF/XPS in PowerPoint, File → Export To → PDF in Keynote, File → Download → PDF Document in Google Slides. Those exports keep the text live; this one doesn't.

What doesn't carry over

• SmartArt and charts — the slide will have empty space where they were. Workaround: in PowerPoint, right-click the SmartArt or chart, choose "Save as Picture," and paste the image back over it. The conversion will then render it.
• Tables with complex cell fills — the text comes through, but cell borders often don't. Screenshot the table and paste as an image if the borders matter.
• Slide animations and transitions — PDF doesn't support motion, so you'll see the static end-state of each slide as if every animation has finished playing.
• Speaker notes — these are a separate layer that the audience never sees during a presentation. They don't make it into the PDF either. If you need a PDF with notes, use PowerPoint's "Notes Pages" export.
• Audio and video — PDF doesn't support media playback, only the static poster image of any embedded media stays.

If the PDF doesn't look right

• Fonts look slightly different — the device running the conversion doesn't have the original font installed and the browser substituted a similar one. The fix: convert on a machine that has the font, or embed the font into the .pptx in PowerPoint (File → Options → Save → Embed fonts in the file) before converting.
• A slide is blank — it most likely contained only SmartArt or a chart. Replace those with images and re-run.
• Text is cut off at the edge — the text box overflowed the slide in PowerPoint, where the program was hiding the overflow. Resize the box or shrink the type and re-save the .pptx.

What happens to your file

The .pptx opens in your browser's memory and is converted on your device. Nothing — not the file, not fragments, not metadata — gets sent to our server. To verify, open DevTools, switch to the Network tab, and drop the file: you'll see no outbound requests carrying its contents. This matters for theses with personal data, internal sales decks, financials, or anything where you'd prefer the slides not sit on someone else's disk.
