How It Works

Step-by-step guide to resize image to passport size 3.5x4.5cm to exact specifications

Upload a photo

Choose a JPG, JPEG, PNG, or WEBP file from your phone or computer. A front-facing shot with even lighting crops cleanest, but the tool works with most clear photos.

Auto-fit to 3.5x4.5 cm

Auto mode finds your face, centers it, and scales the frame to the 3.5x4.5 cm target while replacing the background. Switch to Manual mode to adjust the crop or background yourself.

Download your photo

Save the print sheet for a physical copy or the digital file for an online upload. Both match the 3.5x4.5 centimeter, 413x531 pixel target at 300 DPI.

Frequently Asked Questions

Everything you need to know about image resizing

How many pixels do I get when I resize image to passport size 3.5x4.5cm at 300 DPI?

3.5 centimeters by 4.5 centimeters works out to 413x531 pixels at 300 DPI. This tool outputs that exact pixel size so the printed photo measures correctly with a ruler once developed.

Why do some application forms list photo sizes in centimeters instead of inches?

Most countries outside the US use the metric system, so passport, visa, and ID forms from those countries print photo requirements in centimeters rather than inches. This page targets that exact figure, so when you resize image to passport size 3.5x4.5cm here, no unit conversion is needed on your end.

Does it matter if my form writes the size as '3.5 cm x 4.5 cm' instead of '3.5x4.5cm'?

No — those are the same measurement written two different ways. Whether your form spells out 'centimeters' or shortens it to 'cm', this tool targets the identical 3.5 by 4.5 centimeter output either way.

Why does this form say 3.5x4.5cm instead of 35x45mm?

Both describe the exact same physical size — 3.5 cm equals 35 mm, and 4.5 cm equals 45 mm. Forms just pick whichever metric unit their country's paperwork conventions use. When you resize image to passport size 3.5x4.5cm here, you get the identical output either form would require.

Are there other passport photo sizes commonly measured in centimeters?

Yes, some forms ask for sizes like 4x6 cm or 4.5x3.5 cm depending on the country and document type. Check your specific form for its exact figure — this page is built for the 3.5x4.5 cm requirement.

Should I re-measure my printed photo to confirm it's exactly 3.5x4.5 cm?

It's a good habit, especially with a home printer. Hold a ruler against the printed copy — since the file is generated at 413x531 pixels for 300 DPI, a correctly configured printer should produce a photo that measures 3.5 by 4.5 centimeters.

Will my photo be uploaded to a server?

No. Cropping, background replacement, and resizing all run locally inside your browser. Your photo is never sent anywhere, so it stays private on your own device.

Is 3.5x4.5 cm the same thing some countries call a standard 'passport photo' size?

In many countries that use centimeters, 3.5x4.5 cm is a common photo size for passport, visa, and ID documents. Terminology and exact requirements still vary by country and issuer, so confirm the figure on your specific form before submitting.

How do I resize image to passport size 3.5x4.5cm if my software only accepts inches?

3.5x4.5 cm works out to roughly 1.38 by 1.77 inches. You don't need to do that math yourself — resize image to passport size 3.5x4.5cm here and download the finished 413x531 pixel file, which already matches the centimeter figure your form asked for.

Can I use the same 3.5x4.5 cm crop for both a passport and a national ID form?

Many passport and national ID forms in centimeter-using countries request the same 3.5x4.5 cm photo box, but requirements vary by document and issuer. Confirm the size printed on each specific form before reusing one crop for both.

Will a photo printing shop in a metric country accept this 3.5x4.5 cm file directly?

The digital download is generated at the 3.5x4.5 cm, 413x531 pixel target. If a shop asks for a different format, Manual mode lets you re-export before you go.

How does Manual mode differ from Auto mode when I resize image to passport size 3.5x4.5cm?

Auto mode detects your face, crops it, and swaps the background automatically in one pass. Manual mode separates those steps so you can fine-tune the crop or background yourself — useful for busy or uneven original photos.
