How to Convert CM to Pixels for Image Resizing
Many forms require images in exact cm or mm measurements. To convert cm to pixels, a standard DPI value is used. Most photos use 150 DPI, which equals approximately 59 pixels per centimeter.
Example Calculation
Convert a 3.5 cm × 4.5 cm passport photo:
- Width: 3.5 cm × 59 px = 207 px
- Height: 4.5 cm × 59 px = 266 px
Photo: cm → pixels calculator
Formula: pixels = cm × (dpi ÷ 2.54) — (1 inch = 2.54 cm)
How to Resize an Image to 100KB
- Upload a high-resolution image for best results.
- Select the required output dimensions.
- Crop and adjust the image in the preview box.
- Choose the 100KB option under compression settings.
- Download the optimized file.
