UK passport photo upload failed? The file limits, and how to meet them

The photo for the online UK passport application is a digital file, and the official page publishes limits for it: pixel size at least 600 x 750 pixels (width x height); file size 50 KB to 10 MB. A file outside any one of them does not meet the published limits. WinPhoto ID checks your file as it is against these limits and the published photo rules. The check is free.

Your photo stays on your device: nothing is uploaded, and no face is recognised.

The published file limits

For the UK passport, online application (digital photo). The indented words are the issuing authority's own, from the official page linked under them, read on the date given. WinPhoto is photo software, not an application service. WinPhoto is not affiliated with any government. Only the authority decides whether it accepts a photo.

Limit	As published

GOV.UK crops the photo itself and asks you not to crop a photo taken on your own device, and someone else must take it. So this page checks your photo as it is and never crops or re-saves it: upload that same file.

The usual reasons a file is refused

Each of these puts a file outside the limits above:

The image is smaller than 600 x 750 pixels.
The file is larger than 10 MB or smaller than 50 KB.

This list comes only from the published limits. A photo can also be turned down for what it shows, such as the background or the head size: the UK passport photo online page has every published rule.

What the free check does

The page reads your file as it is and checks its pixel size and file size against the limits above.
It also checks the photo itself against the published photo rules it can measure, such as the background.
It never crops, edits or re-saves the file.

Checking your photo is free and runs in your browser. A file made or checked here meets the published limits as read on 4 November 2026; it is not a promise that the authority accepts it.
