Export presentation to PDF without losing quality (3 methods tested)
PowerPoint to PDF often degrades quality: images compress, fonts substitute, charts pixelate. Three methods that preserve fidelity: (1) SlideGMM native PDF export at 300 DPI; (2) PowerPoint File → Export with "preserve fidelity" checked; (3) Adobe Acrobat with font-embedding override.
Frequently asked questions
Three usual culprits: (1) PowerPoint defaults to "minimum size" PDF compression — switch to "standard" or "high quality" in Export dialog; (2) custom fonts not embedded — Acrobat substitutes with sans-serif fallback; (3) images downsized — disable "compress images" option.
In PowerPoint: File → Info → Options → Save → "Embed fonts in the file" → check "Embed all characters." For Acrobat: Preferences → Documents → "Always Use System Fonts." SlideGMM's PDF export embeds fonts automatically.
Different. Print: 300 DPI images, CMYK color profile, embedded fonts (PDF/X-1a standard). Screen: 72-150 DPI is sufficient, RGB color profile, web-optimized. SlideGMM has separate export presets for each — pick "Print" before sending to printer.
