Frequently Asked Questions

How do inches translate to digital pixels in an image?

Pixels = Inches × DPI (Dots Per Inch). For example, a 4×6 inch photo at 300 DPI equals 1200×1800 pixels. PDFtiny calculates the exact pixel matrix automatically.

What DPI should I choose for photo prints and frames?

300 DPI is the gold standard for crisp photo lab prints and framed portraits. 150 DPI is acceptable for larger posters or canvas art.

What standard photo print sizes in inches are included?

Includes presets for 2×2 (US passport), 4×6 (standard postcard), 5×7, 8×10 (portrait frame), 11×14, and custom inch inputs.

Can I print directly from the resized file?

Yes, download the resized file and send it directly to your home printer or photo lab kiosk without unexpected cropping.
