About this tool

PowerPoint decks shared as .pptx files are a minor disaster because the recipient opens them in whatever version of PowerPoint or Keynote they have, fonts get substituted, image placements shift, and animations either play awkwardly or do not play at all. PDF fixes all of that. This tool uploads your .pptx to a server in Germany (Hetzner data center) running LibreOffice Impress, which renders each slide to a PDF page at the slide's original dimensions and orientation. Fonts get embedded so they render correctly on any machine. Colors, charts, images, and shapes all carry through. The file is deleted from the server within 10 minutes. The trade-off is that animations and transitions are not preserved — PDF has no concept of motion. The static visual content (the final state of each slide) is what you get. The how-to below covers the flow and the FAQ explains what happens to embedded videos, custom fonts, and Keynote files.

How to powerpoint to pdf converter free

  1. Upload your .pptx

    Drag and drop or click to browse. Modern .pptx files (PowerPoint 2007 and later) work, as does .odp from LibreOffice Impress and PowerPoint-exported Keynote files.

  2. Wait for the conversion

    LibreOffice Impress renders each slide at the slide dimensions you set in PowerPoint. A 60-slide deck takes about 6-10 seconds.

  3. Download the PDF

    Output is a multi-page PDF with one slide per page. Slide dimensions match the source (16:9 widescreen, 4:3 standard, or whatever custom size you set).

  4. Verify before sending

    Open the PDF and skim slides. Common issues: a missing font substituted (visible if you used a custom typeface), or an embedded video showing as a static frame.

Why use this tool

You are sending a deck to a client and the brief said "PDF, please" because they do not want the deck to be edited or replayed in a different format. You are submitting a conference talk's slides to a portal that accepts only PDF. You are sharing a presentation with someone who does not have PowerPoint installed (Chromebook, iPad, Linux laptop) and want them to actually be able to view it. You are archiving an old deck and want a format that will still open in 10 years without depending on the current Microsoft Office version. You are printing handouts and need a paginated PDF version for the print shop. You are uploading slides to a learning management system that only accepts PDF for distribution. You are sending teaching material to students who use a mix of devices. PPTX-to-PDF is the freeze-everything step that turns a live presentation into a portable artifact.

Features

Layout fidelity

Each slide in the deck becomes one PDF page at the original slide dimensions. So a 16:9 widescreen deck gives you a widescreen-aspect PDF; a 4:3 deck gives you a 4:3 PDF; a custom-sized deck (square Instagram-aspect, anything else) keeps its custom dimensions. Fonts get embedded, colors are exact, images stay at source resolution, and shapes are rendered crisp with proper anti-aliasing. The output is what you would see if you took a high-quality screenshot of each slide.

Universal format

PDFs open everywhere — Mac Preview, Windows Edge, Adobe Reader, every mobile PDF app, every web browser, every print system. No PowerPoint needed to view. This is the main reason PDF is the standard for shipping presentations: you do not have to ask "do you have PowerPoint?" or worry about which version. Send the PDF and trust it works. The recipient does not need a Microsoft account or any Office license.

No watermark or stamp

Clean output, no "converted by" footer, no QR code in the corner, no nag screen, no banner. The PDF is exactly the deck's content. This sounds basic but several big-name converters insist on stamping their brand somewhere visible — this tool does not. The output is suitable for client-facing material, conference submissions, and anything else where a third-party watermark would look unprofessional.

Quick conversion

Most decks finish in seconds. A 30-slide deck takes about 4 seconds; a 60-slide deck about 6-8 seconds. Even a 200-slide training deck typically converts in under 30 seconds. There is no queue and no rate limit; the server processes one request at a time per uploader and recycles LibreOffice workers between conversions, which keeps cold-start latency low.

Privacy & security

For this tool your file is uploaded to our server over HTTPS, transformed, and returned to you. The uploaded file and all derived outputs are automatically deleted within 10 minutes — there is no long-term storage and we do not retain copies. We do not inspect file contents, run analytics on them, or share them with third parties. If a stronger privacy guarantee matters for your workflow, prefer one of our local-only tools where the file never leaves your browser.

Frequently asked questions

Will animations and transitions be preserved?
No. PDF has no concept of motion or timing — it is a static document format. The conversion renders the final visible state of each slide, which is what most viewers see anyway after the build completes. If your deck relies heavily on click-by-click reveals (a process diagram revealed step by step, a build-up of bullet points), the PDF will show all elements at once. Consider exporting one PDF per build state if that matters for the audience.
What about embedded videos?
Videos cannot play in PDF — the format does not support inline video natively. The conversion renders the video's poster frame (or first frame if no poster is set) as a static image in the PDF. If your deck depends on video for the message to land, share the .pptx instead, or extract the videos and share them separately with timestamps tied to the slide numbers in the PDF. There is no good cross-platform answer to video-in-PDF; PDF readers that do support it are rare.
Will my custom fonts render correctly?
Yes if the server has the font installed. The server has the standard Microsoft set (Calibri, Arial, Times New Roman, Cambria, Tahoma, etc.) plus a wide selection of Google Fonts. If your deck uses a less common font, LibreOffice substitutes a similar one and the substitution may be visible — letter spacing changes, line breaks shift. If font fidelity is critical, embed fonts in the .pptx in PowerPoint (File > Options > Save > Embed fonts in the file > Embed all characters) before uploading.
Does it work with Keynote files?
Not directly with .key files. Export from Keynote as PowerPoint first (File > Export To > PowerPoint), then upload the resulting .pptx. Keynote's export is usually clean — fonts and layouts carry through to PowerPoint format, and then through this tool to PDF. The double export does add a small amount of drift on complex animations, effects, and Keynote-specific features (Magic Move, smart builds) that have no PowerPoint equivalent.
Where does my file go?
Uploaded over HTTPS to our server in Germany (Hetzner data center). The .pptx is processed in a temp directory by LibreOffice Impress, the output PDF is sent back to your browser, and both files are deleted from the server within 10 minutes by a janitor process. No contents are logged, no copies are kept, and no third-party analytics touch the conversion path.
How big a deck can I convert?
50MB per upload. Most decks are well under this — even a 50-slide deck with lots of images typically lands at 10-20MB. The cases that hit the limit are usually decks with embedded video (which takes huge space) or hundreds of high-res photos at original resolution. For those, swap in compressed versions of the images (PowerPoint's File > Compress Pictures > Email size) before uploading. Remove embedded video from the source file if you do not need it in the PDF.
Can I export individual slides as separate PDFs?
Not directly from this tool — the output is one PDF containing all slides. After downloading, you can use the PDF split tool here to extract individual pages (each PDF page is one slide). Or if you only need specific slides, delete the others in PowerPoint before uploading (or hide them — hidden slides are not exported by LibreOffice). The two-step flow takes about 30 seconds.
Will speaker notes appear in the PDF?
By default, no — only the slides themselves are exported. PowerPoint's Save-as-PDF has an option to include speaker notes (one slide per page with notes underneath), but this server-side conversion uses LibreOffice's default which is slides-only. If you need notes in the PDF, the workaround is to use PowerPoint's own export (File > Export > Create PDF > Options > Publish what: Notes pages) on a desktop install before sharing.
Why are some of my colors slightly different?
PowerPoint and LibreOffice handle color profiles slightly differently for certain edge cases (custom theme colors, gradients with specific stop positions, transparency effects layered on top of patterns). For most decks the differences are imperceptible. For brand-critical color matching (corporate decks with strict color specs), use PowerPoint's own export on a desktop install — it has access to the original color rendering pipeline.
Does it preserve hyperlinks within the deck?
Yes for external URLs (clicks open in a browser) and mostly yes for internal slide-to-slide links (click jumps to the linked slide within the PDF). Slide-to-slide links work because PDF supports internal page links. Action buttons configured to run a macro do not work in PDF (no macro engine), but action buttons configured to jump to a slide do work as page links.
Will the PDF be searchable?
Yes, the text on each slide stays as a real text layer in the PDF, so search and select work normally. This is one of the advantages of converting from .pptx (which has structured text) rather than printing or screenshotting slides. Recipients can use Ctrl+F in their PDF reader to find any text in the deck. Image-based slide content (text rendered as part of an image) is not searchable; that is unavoidable without OCR.
What about handout layouts (multiple slides per page)?
Not in this version — the conversion produces one PDF page per slide at the slide's original dimensions. For handout-style output (2, 4, 6, or 9 slides per page), use PowerPoint's own export on a desktop install (File > Export > Create Handouts > Choose layout), or convert to one-slide-per-page first here and then use a desktop PDF tool to combine slides onto sheets. Multi-slide-per-page conversion is on the roadmap but adds complexity to the UI.
How does this compare to Google Slides export?
Google Slides has its own "Download as PDF" option which is fine when you are already working in Google Slides. If you have a .pptx file (not a Google Slides doc), uploading to Drive to convert is an extra step compared to using this tool directly. For Google Slides → PDF, use Google's own export. For PowerPoint .pptx → PDF without round-tripping through Drive, this is faster.
What if my deck has both 16:9 and 4:3 slides mixed?
PowerPoint does not actually support per-slide dimensions within one deck — the slide size is set at the deck level and applies to all slides. If you imported content from differently-sized decks, the imported elements may look stretched or letterboxed but the slide canvas itself is uniform. The PDF output preserves whatever single slide size the source deck specifies. To get mixed sizes in a final PDF, split the source into per-size sub-decks, convert each, and merge with the PDF merge tool.
