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.

This image resizer by pixels targets precise dimensions for ads, favicons, and platform requirements. Enter width and height in pixels, maintain aspect ratio if needed, and export a correctly sized image without desktop software.

Platforms publish required pixel sizes—YouTube thumbnails, Open Graph images, and favicons all have exact specs.

When both dimensions are specified without aspect lock, the image may stretch—use lock unless intentional cropping follows.

How to use this tool

Upload your image, enter pixel width and height, enable aspect lock if proportional scaling matters, then download.

Worked example

Example: resize a logo to exactly 512×512 pixels for an app icon submission without distortion.

When to use this

  • App store and favicon asset generation.
  • Banner ads with fixed IAB sizes.
  • Documentation screenshots needing uniform width.

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 DPI for screen use.
  • Cropping instead of resizing when aspect ratios differ.
  • Using non-uniform stretch on logos.

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.

FAQ

Frequently asked questions

Pixels vs inches?

Screen display uses pixels. Inches depend on DPI—this tool sets pixel dimensions directly.

Will quality stay sharp?

Downscaling usually looks fine. Upscaling beyond original size may blur.

Can I resize PNG with transparency?

Yes. PNG alpha channels are preserved in standard browser resize paths.
