How it works

Drag & drop or choose PPTX files (also supports PPTM, POTX, POTM). No account required—paid plans unlock bigger batches, higher limits, and priority queues.

- 3 · Download & auto-delete
Get pixel-perfect PDFs with preserved slide order. Files delete automatically after 1 hour. Delete anytime after downloading with one click.
Modern PowerPoint presentations use Office Open XML (OOXML) formats introduced in PowerPoint 2007: PPTX (standard presentations), PPTM (macro-enabled), POTX (templates), and POTM (macro-enabled templates). These formats store content as compressed XML files inside a ZIP container, making them more compact, resilient to corruption, and easier for third-party tools to process.

PowerPoint supports slides, animations, transitions, embedded media, speaker notes, and custom fonts. For reliable sharing, archiving, or cross-platform viewing, converting to PDF or images ensures your presentation appears exactly as intended regardless of the viewer's software. Legacy binary .ppt files (1997-2003) require re-saving as PPTX in PowerPoint before conversion.
PDF (Portable Document Format) is Adobe's universal document standard, designed to present text, images, and layout consistently across any device or platform. First released in 1993 and later standardized as ISO 32000, PDF supports vector graphics, embedded fonts, forms, annotations, and encryption. It has become the de facto format for document exchange, digital publishing, and archival—billions of PDFs are created daily worldwide.

PDF excels at preserving document fidelity and works universally—every operating system and browser includes native PDF support. For long-term archival or regulatory compliance, PDF/A is the appropriate variant.
Frequently Asked Questions
Which PowerPoint formats are supported?
We support modern Office Open XML PowerPoint formats: .pptx, .pptm, .potx, and .potm.
Macro-enabled files (PPTM/POTM) are converted with macros disabled in the PDF output.
Legacy binary .ppt files are not supported; re-save them as PPTX in PowerPoint before uploading.
Should I use PDF or PDF/A?
Use this PDF converter for everyday sharing: decks you email, print, or protect with passwords; smaller file sizes and fast delivery.
Use PDF/A for archival/compliance: legal, government, medical, or records that must remain readable for decades. PDF/A embeds fonts/color profiles and forbids encryption. Switch to our PPTX to PDF/A converter for ISO 19005-2 compliance.
What happens to animations, videos, and transitions?
Animations and transitions: Flattened to static frames showing the final state of each slide.
Embedded audio/video: Not preserved in PDF output—PDF is a static format.
Presenter notes: Excluded from the PDF to keep focus on slide content.
Hidden slides: Excluded from the PDF. Only visible slides appear in the output.
Tip: Unhide any slides in PowerPoint before uploading if you need them in the PDF.
What happens to images and fonts?
Images: Exported at high quality (≈90% JPEG) to balance fidelity and size; vectors are rasterized for consistency.
Fonts: Fully embedded so your deck looks identical on any device—even without your custom fonts installed.
Do you support password-protected PowerPoint files?
No. Encrypted presentations cannot be opened by the converter. Remove protection in PowerPoint before uploading.
PowerPoint steps: File → Info → Protect Presentation → Encrypt with Password → clear the password → Save.
Why does my PowerPoint PDF look blurry?
Our converter renders images at 90% JPEG quality—a balance between file size and visual fidelity that works well for most presentations.
If your PDF looks blurry, check these common causes:
- Low-resolution source images: Images in your PPTX that are already low-resolution will appear the same in the PDF
- PDF viewer zoom: Some viewers render at lower quality when zoomed out—try viewing at 100%
- Vector graphics: SmartArt and complex shapes are rasterized for consistent rendering, which may slightly reduce sharpness
For highest quality, use high-resolution images in your source presentation.
What are the limits for this converter?
| Tier | Max File Size | Max Files/Batch | Parallel Processing |

How are credits calculated for this conversion?
Cost: 1 credit per 25 MB
How it works:
- Files up to 25 MB: 1 credit (minimum)
- 26-50 MB: 2 credits
- 51-75 MB: 3 credits
- 76-100 MB: 4 credits
- Over 1000 MB: 40 credits (maximum cap)
Example: A 5 MB presentation = 1 credit. A 95 MB presentation = 4 credits.
Why per-megabyte? Larger files require more resources (processing, bandwidth, storage).

| Free | 50 credits/day | — |
| Pro | — | 10,000 credits/month |
