Understanding DPI & Pixels

Confused about DPI and pixels? Here's a simple explanation to help you choose the right size.

🖥️

72 DPI (Screen)

Used for web images, social media, and digital displays. Lower resolution but smaller file size.

2×2 inch = 144×144 pixels

🖨️

300 DPI (Print)

Standard for printing. Recommended for passport photos, professional prints, and official documents.

2×2 inch = 600×600 pixels

📸

600 DPI (High-Res)

Ultra-high quality for professional photography, large prints, and detailed archival work.

2×2 inch = 1200×1200 pixels

💡 Pro Tip: For passport photos, always use 300 DPI. Government agencies require high-quality prints, and 300 DPI ensures your photo looks sharp and meets official requirements.

Frequently Asked Questions

How do I resize an image without losing quality? ▼

Making images smaller (downscaling) generally maintains quality. Our tool uses high-quality resampling algorithms to preserve sharpness. For upscaling (making images larger), some quality loss is inevitable, but we minimize it. For best results, start with a high-resolution original.

What size should I use for passport photos? ▼

It depends on your country:

USA/India: 2×2 inches (600×600 pixels at 300 DPI)
UK/EU/Schengen: 35×45mm (413×531 pixels at 300 DPI)
China: 33×48mm (390×567 pixels at 300 DPI)

Use our presets to get the exact size for your country.

What does "maintain aspect ratio" mean? ▼

Aspect ratio is the proportional relationship between width and height. When you lock the aspect ratio (the 🔗 button), changing one dimension automatically adjusts the other to prevent distortion. Unlock it if you want to stretch or squish the image to exact dimensions.

How do I convert inches to pixels? ▼

The formula is: Pixels = Inches × DPI

For example, at 300 DPI:
• 2 inches = 2 × 300 = 600 pixels
• 1 inch = 1 × 300 = 300 pixels

Our tool does this conversion automatically when you select "Inches" as the unit.
