35×45 mm · 600×750 px @ 300 DPI
Government photo-ID applications enforce strict pixel and millimetre specifications because rejection costs the applicant another visit and the issuing office processing time. UK Passport Photo is the spec used for the UK passport / visa photo standard; if your submitted image misses the dimensions or compression ceiling, the system flags it before a human sees it. This preset crops to 35×45 mm passport and exports 600×750 JPEG @ 300 DPI, matching the published guideline. Most rejections happen for one of three reasons: wrong physical dimensions, non-white background, or the source resolution was too low to upscale cleanly to 600×750 JPEG @ 300 DPI.

The UK photo standard is administered by His Majesty's Passport Office (HMPO). United Kingdom member states have generally aligned with the 600×750 px specification at 300 DPI, though local rejection criteria vary.
Where this preset's output is accepted: first adult / child UK passport, passport renewal, biometric residence permit (BRP) replacement, Settlement Scheme submissions, and most UKVI visa categories.
Travel-document context: U.K. passport holders enjoy visa-free or visa-on-arrival access to 191 destinations, ranking 4th globally on the Henley Passport Index 2024 Q4. The photo specifications described on this page apply to the document used for that travel.
Country-specific note: HMPO's online check rejects photos with closed mouths if teeth are visible (smile lines around the mouth count), and the head measurement must be 29-34 mm from chin to crown — a tighter band than most other countries. Run this preset, then verify the result against the official guidelines linked in the specifications table above before submitting.
This preset is a deterministic recipe — every step has fixed parameters so the result is byte-identical across runs of the same input.
UK Passport Photo crops your input to 35:45 and resizes it to 600×750 px as JPEG — a 450-kilopixel output. The work runs through canvas APIs and a WebAssembly image-encoder; the source image is decoded into an off-screen canvas, transformed in place, and re-encoded without any network upload.
Government photo-ID portals pre-validate the image dimensions before accepting upload; matching the spec exactly skips the rejection round-trip. The browser-side path also means the file never leaves your device — relevant when the input contains personally identifiable information, screenshots of private documents, ID scans, or proprietary product photography.
600×750 px at 300 DPI, saved as JPEG at quality 92%.
The UK Passport Photo regulation specifies a printed photo of 35×45 mm. The pixel ratio matches the millimetre ratio so the image prints at the correct physical size when the file is opened at 300 DPI.
300 DPI is the print-grade resolution at which the dot pattern disappears at normal reading distance. Government photo offices, commercial print shops, and biometric scanners all assume 300 DPI; anything lower prints visibly soft.
The target accepts JPEG, and JPEG compresses photographic content 5-10× smaller than PNG with no visible difference at quality 92%. PNG is the right choice only when the image has hard edges or transparency — which photo-ID, social posts, and product photos don't.
No. This preset runs entirely in your browser using WebAssembly + canvas APIs — no server round-trip. You can verify this in your browser's network panel: only static asset requests, no image upload. The file never leaves your device.
