PowerPoint to PDF
Convert PPTX, PPT, or ODP presentations to PDF. Server-side LibreOffice engine. Free, no signup, no watermark.
Server-side processing
Your file uploads over HTTPS, gets converted by LibreOffice, then deleted immediately. Nothing logged or stored.
Convert PowerPoint presentations to PDF online. PPTX, PPT, ODP supported. Layout and fonts preserved.
PowerPoint to PDF is the standard format conversion when you need to share a presentation that opens identically on every device — no font substitution, no "PowerPoint required", no Mac/Windows formatting drift.
Pick Rack's PPTX to PDF tool runs server-side using LibreOffice's headless engine — the same engine that powers WordPress's wp-cli media regenerate and most enterprise document servers. Files upload over HTTPS, get rendered to PDF, and are deleted immediately. We never log or store your file.
Free, no signup, no watermark. PPTX, legacy PPT, and OpenDocument ODP files are all supported, up to 50MB. Conversion typically takes 5-15 seconds depending on slide count.
Key features
- Preserves slide layout exactly — Bullets, tables, images, and shapes render to PDF in their original positions. No reflow, no font size jumps.
- Embeds custom fonts — If your PPTX uses non-standard fonts available on the LibreOffice server, they're embedded in the PDF. Otherwise, the closest substitute is used (rare on modern decks).
- Handles 100+ slide decks — Conversion is linear in slide count. A 200-slide investor pitch converts in ~30 seconds.
- Animations rendered as static slides — Each slide is captured at its initial state. Animation steps are not preserved in PDF (PDF doesn't support animation).
- Speaker notes excluded by default — Output PDF contains slide content only — clean for sharing without "internal notes" leaking. (Speaker-notes export coming in v2.)
How to use
- Step 1: Upload your presentation — Drag a PPTX, PPT, or ODP file (up to 50MB) into the dropzone.
- Step 2: Click Convert to PDF — LibreOffice processes your file server-side. Wait 5-30 seconds depending on slide count.
- Step 3: Download the PDF — A green download button appears. Click to save the converted PDF to your device.
When to use
- Send a deck to a client who doesn't have PowerPoint installed
- Archive a presentation in a format that won't degrade as PowerPoint versions change
- Print a deck with consistent formatting (PowerPoint print preview can drift between versions)
- Upload to a job application that requires PDF format only
- Email a slide deck that opens identically on Mac, Windows, iOS, Android
- Embed in a PDF portfolio combining multiple decks into one file via Merge PDF
Frequently asked questions
Why use server-side LibreOffice instead of browser conversion?
Browser-based PPTX rendering is unreliable — the OOXML format is too complex for any JavaScript library to render with full fidelity. LibreOffice has 25 years of engineering invested in PowerPoint compatibility, including the same code Microsoft uses internally for Office Online compatibility testing.
Will my custom fonts render correctly?
If the font is embedded in your PPTX (use File → Options → Save → "Embed fonts" in PowerPoint), yes. If it's only referenced by name and not available on the server, LibreOffice substitutes the closest match — usually visually identical for common fonts (Calibri, Arial, Helvetica).
Does this support PowerPoint's built-in animations and transitions?
No — PDF doesn't support animation. Each slide is exported in its initial visual state. If you need animated output, export from PowerPoint as a video (MP4) instead.
What about embedded videos and audio?
Videos and audio are not embedded in the PDF (PDF supports embedded media but most viewers don't reliably play them). The slide where they were placed shows the poster image only.
Are speaker notes included in the PDF?
No, speaker notes are excluded by default — output is the slides only. This matches how most users share decks (notes are private to the presenter). A speaker-notes export option is on the roadmap.
Is there a slide count limit?
Effective limit is the 50MB upload cap and 90-second conversion timeout. Most decks of up to 200 slides convert successfully.
Why is my converted PDF much larger than my PPTX?
PPTX is highly compressed and references images/fonts. PDF embeds them as raw streams. A 5MB PPTX with high-resolution images often becomes a 15-30MB PDF. Run Compress PDF on the result to shrink it 50-80%.
What's the difference between PPTX, PPT, and ODP?
PPTX is modern PowerPoint (Office 2007+). PPT is legacy PowerPoint (1997-2003 binary format, OLE2). ODP is OpenDocument Presentation, used by LibreOffice Impress, Apache OpenOffice, and Google Slides export. All three are supported.
