Preguntas Frecuentes
What is PPI versus DPI?
PPI (pixels per inch) is for screens; DPI (dots per inch) is for printing. Different standards apply.
Is higher resolution always better?
No, excessive resolution wastes storage and processing power. Match resolution to actual use case.
What is Retina display resolution?
Retina typically means 2x standard PPI, around 300+ PPI. Human eye can't distinguish individual pixels.
How do I calculate web image resolution?
Use actual display pixel dimensions (e.g., 1200x800 pixels for web). Use 72 DPI for file size estimates.
Can I reduce resolution without losing quality?
Downsampling at proper aspect ratio maintains quality better than cropping. Always resize rather than crop for optimization.
