How we test and verify specifications

The ID, passport and visa photo pages on PixlReady are built from primary sources, then re-checked against them. This page explains exactly how, so you can judge whether a number on our site is worth trusting.

1. Where our numbers come from

Every specification we publish is taken from a primary source: the passport office, immigration authority, or official visa application portal of the country in question. We do not copy figures from other tool sites, forums, or photo studios.

Each specification page names its source and shows the date we last checked it.
When two official pages disagree (a common case for dimensional and digital-file rules), we publish both and note which one the receiving system actually enforces.
If a rule is advisory rather than mandatory, we say so instead of presenting it as a hard requirement.

2. How we check a photo against a specification

We verify four things separately, because they fail in different ways and produce different rejections:

Check	What we measure	Why it matters
Geometry	Output pixel dimensions, and head height / head width as a share of the frame	A correct print size with the wrong head proportion is still rejected
File constraints	Byte size ceiling, accepted formats, minimum pixel width applied by the upload system	Portals reject files by size and format before any human sees them
Background and tone	Background uniformity, colour cast, shadow across the face	Off-white or uneven backgrounds are the most common studio failure
Print versus digital	DPI at the required physical size, and the separate digital submission rule	Printing at 300 DPI and uploading a 600 KB file are different requirements

Practical example: some visa portals accept a 240×320 px image but reject anything above 120 KB, while the photo office of the same country asks for a larger print. Both rules are real, and they apply at different steps of the same application.

The figures each portal enforces — pixel minimums, file-weight ceilings and accepted formats — are collected in our upload limits by application portal reference, with the official source for every number.

3. What we test before publishing a page

Run a set of sample photos through the tool at the stated specification and confirm the exported dimensions and byte size match what the page claims.
Confirm the page states the digital rule and the print rule separately when the country publishes both.
Check that the cited source page is still live and still contains the figure we quote.
Record the verification date on the page itself, so a stale figure is visible rather than implied.

4. What we do not promise

We are a preparation tool, not an acceptance authority. Final acceptance always rests with the passport office, consulate, or visa portal reviewing your file.

We cannot guarantee that a photo meeting our published specification will be accepted; reviewers can reject for reasons outside the published rules.
Rules change without notice, sometimes mid-cycle. If you are applying within days of a deadline, confirm the figure on the official page linked from ours.
Our tools run locally in your browser, so we never see, store, or review your photo ourselves.

5. Corrections

If a figure on this site is out of date or wrong, tell us and we will check it against the source and correct the page. Write to JYTCKHFW@jinyuetiancheng.cn with the page URL and the source you are comparing against. Corrections that change a published figure are noted in the page’s verification date.
