United Kingdom Document Guidelines
Applying for a UK visa, passport renewal, or a DBS check? Get the exact photo pixel dimensions, PDF size caps, and format rules for UKVI and GOV.UK portals.
The UK government's Home Office has unified most immigration and identity verification workflows through the UK Visas & Immigration (UKVI) system. Their digital photo standard is relatively generous — accepting files from 50 KB up to 10 MB — but it enforces strict biometric guidelines: the photo must be at least 600 pixels wide and 750 pixels tall (portrait orientation only), and it must be taken against a plain cream or light grey background.
A uniquely British rejection trigger is the background colour rule. UKVI explicitly rejects photos taken against a pure white background (which is acceptable in the US or Canada) — the UK standard requires cream or light grey. This catches many applicants who use the same passport photo for multiple countries.
For immigration applications, many supporting documents like bank statements and payslips must be uploaded in PDF format. UKVI allows up to 50 MB per supporting document file — making it one of the most generous portals — but many employers and banks issue PDFs that are inadvertently too small or too compressed to be legible when UKVI staff zoom in for verification.

United Kingdom Rejection Prevention Checklist
- Cream or Light Grey Background — NOT White: UKVI explicitly requires a plain cream or light grey background. Pure white backgrounds, which are acceptable in the US/Canada, are rejected. This is the most common UK-specific rejection cause.
- Portrait Orientation (Taller Than Wide): The UK photo must be portrait-oriented — at least 600×750 px (width × height). A square or landscape image will fail the UKVI format check.
- No Shadows on Face or Background: GOV.UK guidelines specify that shadows on the face or behind the subject cause rejection. Take the photo in good, diffused natural light.
- Eyes Must Be Open & Looking at Camera: Both eyes must be clearly visible, open, and looking directly at the camera. Photos with downward or sideways glances fail UKVI biometric checks.
- Scanned PDFs Must Remain Legible at 200% Zoom: UKVI caseworkers review uploaded bank statements and payslips at high magnification. Over-compressed PDFs where numbers become blurry cause manual review delays.
Frequently Asked Questions — United Kingdom Document Uploads
Common questions about file sizes, photo requirements, and portal-specific rules.
What background colour is required for UK visa photos?
UKVI and HM Passport Office require a plain cream or light grey background — not white. This is specifically different from US passport photos (which require white/off-white). If your photo has a pure white background, it may be rejected by the UK system. Use our background remover to replace the background with the correct colour.
What is the minimum photo size for a UKVI visa application?
UKVI accepts digital photos from 50 KB up to 10 MB, with a minimum resolution of 600 pixels wide by 750 pixels tall. The photo must be in portrait orientation (taller than wide) in JPEG format.
Can I upload large PDF bank statements to UKVI?
Yes — UKVI allows supporting documents up to 50 MB each, one of the most generous limits among major immigration portals. However, some third-party portals used by visa application centres (like VFS Global) impose lower limits of around 5–6 MB. Always check the specific upload page's instructions.
What documents are needed for an NHS Jobs application?
NHS Jobs typically requires a CV/resume (up to 2 MB, PDF preferred) and professional registration documents such as your NMC (nursing) or GMC (medical) registration certificate. Some trusts also request a DBS certificate or eligibility to work documents. Use our compress PDF tool to ensure your files are under the 2 MB limit.
Is it safe to upload my UK passport scan in a browser tool?
Yes — 100kb.in processes everything locally in your browser. Your passport scan, DBS documents, or NHS credentials are never transmitted to any server. This makes it safe for handling sensitive UK government identity documents.
