Pixel to CM Converter Online - Image Resolution Calculator

Welcome to the OriginalPDF Pixel to CM Converter. Converting digital image pixels (px) into physical printing units like centimeters (cm), millimeters (mm), and inches (in) has never been easier. Whether you are cropping a passport-size photo for an online government job application form (SSC, UPSC, State PSC, Banking, Railways) or setting up canvas dimensions in Photoshop, our calculator delivers 100% precise conversions based on your required DPI/PPI resolution.

100% Client-Side Processing: All calculations are performed locally within your browser. The tool is ultra-fast, safe, and works offline once the page is loaded.

Understanding DPI (Dots Per Inch)

The conversion between a digital pixel and a physical centimeter relies heavily on the DPI or PPI (Pixels Per Inch) of your canvas or monitor.

Conversion Formulas Used

Our tool uses the standard mathematical formulas to ensure pixel-perfect accuracy for your design software (like Photoshop or Illustrator).

* Note: 1 Inch is exactly equal to 2.54 Centimeters.

Frequently Asked Questions

1. How do I convert Pixels to Centimeters?

Simply select 'PX to CM' mode, enter the width and height in pixels, select your target DPI (e.g., 300 for print), and the tool will instantly show the size in centimeters.

2. What DPI should I use for printing a photo?

For high-quality professional printing, you should always set your DPI (Resolution) to 300.

3. What is the standard DPI for web design?

The standard resolution for web images and digital CSS rendering is typically 72 DPI or 96 DPI.

4. How many pixels are in 1 cm?

It depends on the DPI. At 96 DPI, 1 cm is approx 37.79 pixels. At 300 DPI print resolution, 1 cm equals roughly 118.11 pixels.

5. Can I convert CM back to Pixels?

Yes! Switch the mode toggle to 'CM to PX'. Enter your physical dimensions in centimeters, and the tool will calculate the exact pixels required for your Photoshop or Illustrator canvas.

6. What is the formula to convert PX to CM?

The mathematical formula is: Centimeters = (Pixels ÷ DPI) * 2.54.

7. Can I enter a custom DPI value?

Absolutely. If you have a specific monitor or printer resolution, use the custom DPI input box to enter your specific value.

8. What does the Aspect Ratio visualizer do?

The visualizer draws a proportional box representing the shape of your dimensions (Square, Landscape, or Portrait) to give you a real-time visual feel of your canvas.
