Your photo never leaves this tab
Passport size photo, exact mm and KB
Application portals reject photos for two reasons: wrong pixel dimensions, or a file bigger than the KB limit. This tool fixes both in one pass — pick the official size, set the KB ceiling, download. Free, unlimited, and processed on your own device.

Questions
Why 413×531 pixels for 35×45 mm?
That is 35×45 mm printed at 300 DPI, the resolution most application systems assume. If your portal states a different DPI, use its stated pixel numbers instead.
The photo gets cropped — is that expected?
Yes. To hit an exact box without stretching your face, the image is centre-cropped to fill it. Leave some headroom in the original so nothing important is cut.
My portal wants under 20 KB and the result is larger.
Choose JPG output and a smaller dimension preset. If it still cannot reach the limit, the tool tells you and gives the smallest clean result rather than a smeared one.
Do you keep my photo?
No. Everything runs in your browser with no upload, so there is no copy for us to keep.
