If you have a photo and want to verify it matches 3.5x4.5 cm - it does, as long as it was created at 300 DPI.

Compress if the KB is too high

Most 413x531 photos are 100-500 KB. Government portals usually cap at 50KB or 100KB. Use the compressor.

Create one if you don't have it

Open the passport photo maker to crop, resize, and export a fresh 413x531 image.

Frequently asked questions

Is 413x531 pixels really 3.5x4.5 cm?

Yes, at 300 DPI. The formula is pixels ÷ DPI x 2.54 = cm. So 413 ÷ 300 x 2.54 = 3.498 cm ≈ 3.5 cm, and 531 ÷ 300 x 2.54 = 4.492 cm ≈ 4.5 cm.

I have a 413x531 photo but it's 200KB. What should I do?

Compress it. Open the Exact KB Compressor with a 50KB target. It will reduce the file size without changing the pixel dimensions.

What if my photo is 413x531 but at 72 DPI?

The pixel count is correct regardless of the DPI tag. Some portals only check pixels, not DPI. If your portal also checks DPI, use the DPI fixer tool to set it to 300.
