The file isn’t uploaded, resized or changed. DPI is read from the file’s header, where cameras and editors store it.

Measurements

File size, pixels
and DPI appear here

A DPI number is only a label: the pixel count decides how sharp a print can be. Upload portals check pixels and file size, not DPI.

How to check photo size on your phone or computer

iPhone
Open the photo in Photos and swipe up, or tap the ⓘ button. iOS shows the pixel dimensions and file size.

In Google Photos, open the photo and swipe up for Details: file size and resolution.
Windows
Right-click the file, choose Properties, then the Details tab: file size, dimensions and horizontal/vertical resolution (DPI).
Mac

Questions

How do I check a photo’s size in KB?

Choose the photo above. The checker shows the exact size in kB (or MB) and bytes. 1 MB is 1,000 kB here, as most upload portals count it.

What is DPI, and does it matter for an upload?

DPI (dots per inch) is a label stored in the file that tells a printer how large to print it. Upload portals check pixels and file size, not DPI. For a print, divide the pixels by the DPI to get inches.

Why does my photo show no DPI?

Screenshots, web exports and many apps don’t record one. The pixels are what count; the checker also shows the print size at 300 DPI.

How many pixels is a 35×45 mm photo?

413 × 531 pixels at 300 DPI. A 2×2 inch photo is 600 × 600 pixels at 300 DPI.
