Convert Image DPI

What does "Convert to 300 DPI" actually mean?

If you've ever tried to print a photo from the internet, you might have been warned that the image is "Low Resolution" or "72 DPI". This happens because screens display images at 72 or 96 dots per inch (DPI), but printers require much more detail—usually 300 dots per inch—to look sharp.

To fix this, you cannot just change a number in the file settings. You often need to add more pixels to the image so that when it is printed on paper (like a 4x6 photo or an A4 flyer), there are enough dots to cover the space without looking blocky.

How this tool helps you print

This converter solves the "Low Resolution" error in two ways:

1. Metadata Adjustment: It updates the hidden file header to explicitly tell printers "Print me at 300 DPI".
2. Intelligent Resizing: If you specify a print size (like 4 inches wide), we automatically calculate exactly how many pixels you need (4 inches × 300 DPI = 1200 pixels) and resize your image to match.

Common DPI Standards

• 72 DPI: Use this for websites, email, and Facebook. Files are small and load fast.
• 300 DPI: The Gold Standard for printing brochures, business cards, and photos.
• 600 DPI: Used for professional archival scanning or extremely high-detail art prints.
