GOV.UK's online passport service takes a digital photo of at least 750×950 pixels, sized between 50 KB and 10 MB. The unusual part is the minimum — over-compressed photos get rejected. ExactKB respects both bounds and the portrait aspect ratio.
How it works
- Check the target. This page is preset for the spec above — adjust any number to match your exact form.
- Drop your photo. ExactKB finds the best quality and dimensions that land inside the size window — including padding files up when a form has a minimum size.
- Download. The file fits the requirement on the first try.
FAQ
Can I use a phone selfie?
GOV.UK allows photos taken by someone else on a phone against a plain light background — the file just has to meet the size and quality rules. No selfies (arm's length shots distort the face).
Is my photo uploaded to a server?
No. ExactKB runs entirely in your browser. Your file never leaves your device — this page even works offline.
