Quick Answer
To export PPT as high-quality PNG/JPG, you generally need to override the default 96 DPI setting. According to Microsoft Support, modifying the Windows Registry to set the ExportBitmapResolution to 300 guarantees print-ready outputs.
- Navigate to the Registry Editor (regedit) on Windows.
- Create a DWORD value named
ExportBitmapResolutionin PowerPoint Options. - Set the Decimal value to 300 for high-definition exports in 2025.
We have all been there: you spend hours perfecting a slide deck, only to have the exported JPEGs look blurry and pixelated when shared on LinkedIn or Slack. The problem isn’t your design skills; it is the default export settings within PowerPoint. By default, PowerPoint exports slides at 96 DPI (dots per inch), which is fine for 2010-era monitors but insufficient for today’s Retina displays and high-resolution print standards.
In this guide, we will walk you through the exact technical steps to force PowerPoint to export your slides as crisp, high-quality images. Whether you are repurposing slides for social media carousels or print collateral, mastering this workflow is essential for maintaining brand integrity in 2025.
The 96 DPI Problem: Why Your Exports Look Blurry
Most professionals assume that “Save As > JPEG” will render the slide exactly as it looks on the screen. However, PowerPoint compresses images to balance file size and performance. The default 96 dots per inch (DPI) results in an image size of roughly 960×720 pixels for a standard slide.
For modern digital standards, you need at least 1920×1080 (Full HD) or, ideally, 300 DPI for print, which translates to roughly 3000 pixels wide. If you are working with our PowerPoint presentation design team, we ensure these settings are pre-configured, but for individual users, manual adjustment is often required.
Step-by-Step: The Registry Fix for 300 DPI (Windows)
This is the most reliable method to permanently fix low-resolution exports. Note: This involves editing the Windows Registry, so follow these steps precisely.
Configuration Process
- Close PowerPoint: Ensure the application is fully shut down.
- Open Registry Editor: Press
Windows Key + R, typeregedit, and hit Enter. - Navigate to the Path: Go to
HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\PowerPoint\Options. (Note: ‘16.0’ depends on your Office version; it is the standard for Office 2016, 2019, and 365). - Create New Value: Right-click on the right pane, select New > DWORD (32-bit) Value.
- Name the Value: Type exactly
ExportBitmapResolution. - Set Resolution: Double-click your new entry. Select Decimal base and enter 300 in the value data box.
- Restart and Test: Open PowerPoint, go to File > Save As > JPEG/PNG. Your exported image should now be approximately 3000×2250 pixels.
Alternative: The Mac User Workflow
macOS handles image rendering differently, utilizing the PDF engine more heavily. You do not need to edit a registry. Instead, you can control the output resolution by adjusting the slide size specifically for export or using the Preview app.
The easiest method for Mac users is to export the slide as a PDF first. Then, open that PDF in Preview and select File > Export. In the export dialog, you can manually type “300” into the “Resolution” (pixels/inch) box and save it as a JPEG or PNG. This preserves the vector quality of your text before rasterizing it.
Mini Case: Repurposing a Pitch Deck for Social Media
We recently assisted a SaaS client who wanted to turn their Series B deck into a carousel for LinkedIn. Their marketing team was taking screenshots of the slides, resulting in fuzzy text that degraded the brand’s perceived authority.
The Fix: We applied the 300 DPI registry change to their master template machine.
The Result: The text became razor-sharp, and the file size for each image jumped from 150KB to 2MB. When uploaded to LinkedIn, the platform’s compression algorithm had high-quality source material to work with, resulting in a crisp final display that aligned with their premium market positioning.
Common Mistakes to Avoid
Even with high-resolution settings, certain errors can compromise your final image quality.
- Ignoring Aspect Ratio: Ensure your slide size (16:9 vs 4:3) matches your destination platform (e.g., Instagram usually prefers 1:1 or 4:5).
- Using JPEG for Text-Heavy Slides: JPEG uses lossy compression which creates “artifacts” (noise) around sharp text. Always use PNG for slides containing text or charts.
- Forgetting Image Compression Settings: In PowerPoint, go to File > Options > Advanced and check “Do not compress images in file” to prevent PowerPoint from downsampling your imported photos before you even export them.
Pre-Export Checklist
Before you hit “Save As,” run through this quick list to ensure the best output.
- Input Images: Are all photos inside the slide at least 150 DPI?
- Format: Are you choosing PNG for graphics/text or JPG for photos?
- Transparency: If you need a transparent background, have you removed the background color from the slide master?
- Proofing: Have you checked the exported file properties to verify the dimensions are >2000px width?
High-quality visuals are non-negotiable in 2025. If you are struggling with complex formatting or need a deck that looks professional across all mediums, PitchWorx brings over a decade of design expertise to ensure your message is always crystal clear.

Frequently Asked Questions
How do I save a PowerPoint as a high-resolution 300 DPI image?
By default, PowerPoint saves at 96 DPI. To get 300 DPI on Windows, you must add the ExportBitmapResolution DWORD value to the Windows Registry and set it to 300 (Decimal). On Mac, export to PDF first, then export to image via Preview with 300 DPI selected.
Which is better for PPT export: JPG or PNG?
PNG is generally better for presentations because it uses lossless compression. This means text, lines, and logos remain sharp and clear. JPG is smaller in file size but can introduce blurring or “artifacts” around text.
Can I export a single slide instead of the whole deck?
Yes. When you choose File > Save As and select an image format, PowerPoint will ask: “Which slides do you want to export?” Select “Just This One” to export only the currently active slide.
Why are my exported slides still blurry on Instagram?
If your export is high quality but looks blurry on social media, the platform might be compressing it because the file size is too large or the dimensions are incorrect. Try resizing your slide to 1080×1080 pixels exactly before exporting.
