Centimeters vs pixels
Forms often list photo size in cm or mm while cameras and screens work in pixels. Enter centimeters here, set the DPI your spec expects (300 for print, 96 for screen), and download a correctly sized file.
Because the same centimeter size maps to very different pixel counts depending on DPI, ExactPic exposes the DPI field and previews the resulting width × height in pixels so the output is never a guess.
Need to crop image by cm (choose framing first)? Use the passport photo maker’s Custom cm mode — resize here only scales the entire image.

If your form also specifies dimensions or a format, these pages fix everything in one step.
Frequently asked questions
- How many pixels is 3.5 × 4.5 cm?
- It depends on the PPI (pixels per inch) you choose. At 300 PPI — the density most print and passport specs assume — 3.5 × 4.5 cm is about 413 × 531 pixels. At 96 PPI (typical screen density) the same size is only about 132 × 170 pixels. ExactPic defaults to 300 PPI, lets you change it, and shows the exact pixel output before you export.
- Does resize in cm crop the photo?
- No. This tool scales the whole image to the centimeter size you enter. To crop framing (for example head-and-shoulders) and then export at a cm size, use the passport photo maker with Custom cm.
- When should I crop by cm instead of resize?
- Use crop when the subject must sit inside a fixed aspect ratio (passport/visa). Use resize when you only need the full image scaled to print dimensions without changing framing.
