Frequently Asked Questions
What is DPI and why does it matter?
DPI (Dots Per Inch) defines how many pixels are printed per inch. Higher DPI means sharper prints. 72 DPI is standard for web, 300 DPI for print, and 600 DPI for professional printing.
Does changing DPI change the image size?
No. This tool changes only the DPI metadata without resampling pixels. The image dimensions and quality remain exactly the same.
How do I know what DPI my image is?
Upload your image and the tool will automatically detect and display the current DPI. Most digital photos default to 72 or 96 DPI.
What DPI should I use for printing?
300 DPI is the standard for high-quality printing. Use 150 DPI for draft prints. For professional or fine art printing, 600 DPI provides maximum detail.
Can I change DPI for multiple images at once?
Yes! Select multiple files and all will be converted to the same target DPI. Download them all in bulk.
