Will your photo be accepted?

This page measures the things that are in the file: pixel dimensions, shape, file size, format, and whether the image carries colour. Those are the rejections that are avoidable before you submit, and they are the ones nobody tells you about until the application comes back.

It does not look at your face. Head height, eye line, expression, glasses, head covering, whether your shoulders are square, whether the background has a doorframe in it — none of that is measured here, and several of the authorities below care about all of it. Passing every test on this page means the file is right. It is not a prediction that your application will be accepted, and this page will never tell you it is.

The background reading is a measurement, not a verdict: it reports how uniform the outer border of your image is. A plain wall reads low. It is offered as information and never counted as a pass or a fail, because a number cannot tell the difference between a shadow and a cream-coloured curtain.

Each rule is shown with the sentence it came from and a link to the page it was published on. That is deliberate. Specification pages for this kind of thing are mostly written by people reselling photo services, and they are frequently wrong, out of date, or quietly copied from each other.

Where an authority publishes nothing, nothing is checked. The US State Department states no pixel dimensions at all for a passport upload, so this page enforces none — a made-up minimum would fail a photo that would have been accepted, and you would never learn why.

Some differences look like errors and are not. The UK allows 10 MB for a passport and 6 MB for a visa. The US accepts PNG and HEIC for a passport renewal but JPEG only for a visa. Canada accepts black and white; everyone else requires colour. Those are all real, all current, and all easy to get wrong.

Every rule, every measured value and every quotation on this page is free and always will be, including the ones you fail. Telling you that something is wrong and charging you to find out which would convert better and would be a worse thing to have built.

Pro does the repair. One action crops to the required shape, scales into the required pixel window, and searches for the encoding that lands inside the file-size range — including the awkward case where a file is too small, which no compressor solves. EXIF comes off on the way through.
