Resize image to 3.5 cm × 4.5 cm

This page sets exact output size to 413×531 pixels—the usual digital size for a 3.5 cm × 4.5 cm print at 300 DPI. It also starts with a passport-ratio crop so the face fills the frame. Change width or height if your form lists different pixels.

How to use

  1. Add a clear face photo.
  2. Adjust the 3.5×4.5 crop so the face is centered.
  3. Confirm width 413 and height 531 (or the pixels your form requires).
  4. Convert and download the JPG.

Key benefits

  • True cm → px mapping

    3.5×4.5 cm at 300 DPI becomes 413×531 pixels—the size most print and form tools use.

  • Passport crop first

    The crop aspect matches the print ratio before pixels are set.

  • Private

    Resizing stays in your browser.

Why 413×531 pixels?

Physical size alone is not enough for a digital file. At 300 DPI, 3.5 cm is about 413 px and 4.5 cm is about 531 px. That is the default on this page.

Need a smaller file for a portal? After resizing, use Compress to 50 KB or the full Passport Size Photo flow (crop + smaller pixels + 50 KB).
