What size should a passport photo be in pixels?

At 300 DPI, a US 2×2 inch passport photo is 600×600 pixels. For online forms requesting 600×600 or 413×531 (35×45 mm), enter exact pixel dimensions in the resizer. Crop to square first if your source is a vertical phone portrait.

Combine with crop-image when the subject framing must change, not just scale.

How to use this tool

Upload your image, enter pixel width and height, maintain aspect ratio if needed, then download.

Worked example

Example: resize a passport-style headshot to 600×600 pixels before uploading to an application portal.

When to use this

  • Application portals with pixel caps.
  • Favicon and app icon prep.
  • Exact ad placement sizes.

Common examples

  • 4000×3000 phone photo → 1200×900 for a blog content column at 2× retina width.
  • LinkedIn headshot 2000×2000 → 800×800 avatar export.
  • Banner 2400×800 → 1200×400 for faster email newsletter load times.
  • 3000×2000 blog hero → 1600×1067 for faster LCP while keeping 3:2 ratio.
  • Square logo 1024×1024 → 256×256 favicon source before Favicon Generator.

Common mistakes

  • Confusing pixel dimensions with file size KB limits.
  • Stretching instead of cropping to hit square specs.
  • Rounding dimensions that break retina 2× rules.

How it works

Load an image, set target dimensions or a percentage scale, optionally lock aspect ratio, choose an output format, then resize on your device with canvas. Files stay on your device.

Limitations

Upscaling cannot recover detail that was not in the original image. Extreme aspect-ratio changes may crop or distort if not constrained.

Privacy and file handling

Your image stays on your device and is not uploaded.
