Resize by Dimensions
Resize by Percentage
Resize images proportionally by percentage. 50% reduces both width and height by half. 200% doubles the size. Useful for quick scaling without calculating exact dimensions.
Resize in Centimeters (CM)
For print images, enter dimensions in centimeters (e.g., 10cm × 15cm for standard photo). Set DPI to 300 for high-quality printing. Our tool automatically converts CM to pixels based on DPI.
Resize in Inches
US standard measurement for print. Enter dimensions in inches (e.g., 8.5" × 11" for letter size). Set DPI to 300 for professional printing. Automatic conversion to pixels.
Adjust DPI/Resolution
DPI (Dots Per Inch) affects print quality. Use 72 DPI for screen display, 150 DPI for draft printing, 300 DPI for high-quality printing. Higher DPI means more pixels per inch, resulting in sharper prints.
