📐 Step-by-step: convert to cm or inches

1. Upload your photo to the tool of choice.
2. Select units (cm or inches) and enter the target width/height (e.g., 3.5 × 4.5 cm for passport).
3. Set DPI if you’re printing—300 dpi is standard for crisp output.
4. Choose resize mode: keep aspect ratio for undistorted scaling or enable crop/padding when exact measurements are mandatory.
5. Download the resized image and review dimensions in your OS preview or design app.

💡 Pro tips for print accuracy

• Start with the highest-resolution source possible so upscaling artifacts stay minimal.
• Keep a cheat sheet of common dimensions (passport, visa, ID cards) for faster entry.
• Use padding/white borders instead of squeezing portraits if the aspect ratio doesn’t match your required dimensions.
