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/A is an ISO-standardized subset of PDF specifically designed for long-term archival and preservation. Unlike standard PDF, PDF/A prohibits features that could degrade over time—no external dependencies, fonts must be embedded, encryption is forbidden, and all content must be self-contained. The standard ensures documents remain readable and visually consistent decades into the future, making it mandatory for legal archives, government records, and regulatory compliance.
Authoritative reference: ISO 19005-1 (PDF/A-1)
PDF/A is required by many organizations for record retention, legal filings, and regulatory submissions. If archival permanence matters more than file size or advanced features, PDF/A is the correct choice.
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/A output.
Legacy binary .ppt files are not supported; re-save them as PPTX in PowerPoint before uploading.
Should I use standard PDF or PDF/A?
Use PDF/A (this converter) for archival and compliance: legal records, government filings, regulated industries, and anything that must remain readable for decades.
Use standard PDF for everyday sharing: smaller files, optional password protection, and general distribution. Switch to our PPTX to PDF converter if you don't need ISO 19005-2 compliance.
What is PDF/A and why does it matter?
PDF/A is the ISO 19005 standard for archival documents. It embeds all fonts, color profiles, and metadata so your slides render identically decades from now.
PDF/A forbids encryption, JavaScript, audio/video, and external references. Files are typically 10–30% larger to guarantee long-term fidelity.
Which PDF/A level do you produce?
We generate PDF/A-2b (ISO 19005-2, Conformance Level B) for optimal compatibility and visual fidelity.
Level 2 supports transparency and JPEG 2000 compression (smaller than PDF/A-1b) while preserving on-screen and printed appearance.
What happens to animations, videos, and transitions?
Animations and transitions: Flattened to static frames showing the final state of each slide.
Embedded audio/video: Removed to comply with PDF/A requirements.
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.
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.
Do you support password-protected PPTX files?
No. The ISO 19005 (PDF/A) standard strictly forbids encryption and password protection. This ensures archival documents remain accessible decades into the future, even if passwords are lost.
To remove protection: Open the presentation in PowerPoint → File → Info → Protect Presentation → Encrypt with Password → Remove password → Save.
What are the limits for this converter?
| Tier | Max File Size | Max Files/Batch | Parallel Processing |
|---|---|---|---|
| Free | 25 MB | 50 files | 3 at once |
| Pro | 200 MB | 200 files | 6 at once |
| Business | 1024 MB | 1000 files | 10 at once |

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).
What are my daily and monthly credit limits?
Credit allocations vary by account tier:
| Tier | Daily Limit | Monthly Limit |
|---|---|---|
| Free | 50 credits/day | — |
| Pro | — | 10,000 credits/month |
| Business | — | 30,000 credits/month |
Daily credits (Free tier, including guests) reset every day at midnight UTC. Monthly credits (Pro & Business) reset on your billing cycle date.
Note: With 1 credit per 25 MB, a typical document costs 1 credit. Pro users can convert 10000 documents per month.
