How to Change Image DPI in PowerPoint

Default PowerPoint compresses every image to 220 DPI. Three settings control whether your slides print sharp or look soft.

Step 1 — Disable image compression

  1. File → Options → Advanced.
  2. Scroll to Image Size and Quality.
  3. Tick “Do not compress images in file”.
  4. Set Default resolution to High fidelity.

Step 2 — Set the export DPI registry value (Windows)

If you save slides as PNG/JPG via “Save As Picture”, PowerPoint defaults to 96 DPI. To raise this:

  1. Close PowerPoint.
  2. Open Registry Editor (regedit).
  3. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\VER\PowerPoint\Options.
  4. Create DWORD value ExportBitmapResolution = 300 (decimal).
  5. Reopen PowerPoint — saved images now export at 300 DPI.

Caution: registry edits should be done by users comfortable with regedit; back up first.

Step 3 — Tag images at 300 DPI before inserting

PowerPoint honours the embedded DPI metadata at insertion. Run every image through our DPI Converter set to 300 DPI before dropping it into a slide. Verify with the DPI Checker after.

macOS users

macOS PowerPoint exposes Default Resolution in Preferences → General. There is no registry equivalent — pre-tagging at 300 DPI is the most reliable path.
