PowerPoint to PNG Converter

Drop your PPTX file to inspect its slide count and metadata, then follow platform-specific steps to export each slide as a lossless PNG image.

Inspect Your PPTX File

Choose Your Export Method

1

Open your .pptx file in Microsoft PowerPoint (2010 or later on Windows or Mac).

Works on both Windows and macOS.

2

Click File in the top menu bar.

3

Select Save As (Windows) or Export (macOS).

4

In the "Save as type" dropdown (Windows), choose PNG Portable Network Graphics Format (*.png). On macOS, click Save as Pictures and set the format to PNG.

PNG produces larger files than JPG but with zero quality loss — ideal for logos, text, and diagrams.

5

Click Save. PowerPoint asks: "Every Slide" or "Just This One." Choose Every Slide to export the whole deck.

A folder named after your file is created, containing one PNG per slide.

6

Open the output folder — you will find Slide1.png, Slide2.png, and so on for each slide.

Default resolution is 96 DPI on Windows. Apply the registry tweak in the tips below to increase it to 300 DPI.

Tips for High-Quality PNG Output

  • Boost DPI on Windows: PowerPoint defaults to 96 DPI for PNG export. To get 300 DPI, set ExportBitmapResolution in the Windows Registry under HKCU\Software\Microsoft\Office\<version>\PowerPoint\Options to 300.
  • PNG vs. JPG: PNG uses lossless compression, so text, thin lines, and logos stay sharp with no artifacts. Use PNG when quality matters; use JPG only if smaller file size is a strict requirement.
  • Check slide dimensions: A 16:9 widescreen slide at 96 DPI exports at 1280×720 px. At 300 DPI it is 4000×2250 px. Confirm the resolution meets your use-case before batch-exporting a large deck.
  • Reduce PNG file size: If your exported PNGs are too large, run them through Squoosh or PNGQuant for lossy palette compression — this can reduce size by 50–70% with barely visible quality loss.
  • Transparent backgrounds: PNG supports alpha transparency. If your slides have a transparent background, the exported PNG preserves it — useful for overlaying slides on custom backgrounds in video editing or design tools.
