“Convert a photo to passport size” hides a question inside it: whose passport? A US passport photo is 2 × 2 inches. A UK one is 45 mm high by 35 mm wide. Canada wants 50 × 70 mm — and none of those fits a DS-160 upload, which measures pixels and kilobytes, not paper. The part most converters skip: dimensions are the easy half. Government checks measure head height, eye line, background, and file size — and a resizer that scales your photo into the right rectangle fixes at most the file size, never the composition. Here is what each destination actually wants, and how to get a phone photo through it — starting with the converter itself, which is on this page.

The destination decides everything — dimensions, background, file window — so pick it first. Then upload one photo; it is recomposed server-side against that document's official spec, and you see the finished result as a free watermarked preview:

The short answer
There is no universal passport size. Each government publishes its own frame, its own head-height band, and its own background rule — and a photo converted for one will fail another:
The US prints 2 × 2 in (51 × 51 mm), the UK 45 mm high by 35 mm wide (at least 600 × 750 px online), Canada 50 × 70 mm, China 48 × 33 mm — every country's frame, with its head-height band, background rule, recency window and portal pixel spec, is in one table on the passport photo size chart. And if the destination is a US passport, the photo is the cheap part — the 2026 passport cost table has every fee the application itself charges.
The conversion
The converter above takes one phone photo; everything else happens server-side against the official spec for the destination you picked.
The honest limit: output sizes are fixed per destination. This is a compliance pipeline, not a general resizer — if you need a photo at some arbitrary size no government asks for, we do not produce it. Already have a photo you believe in? The free checker measures it against the same bands and alters nothing.
The trap
Resizing solves the easiest requirement on the list. The checks a resize cannot touch:
The fix for the first three is a converter that recomposes. The fix for the last one is a camera.
The source photo
The pipeline can replace a background and solve a crop. It cannot unbend a face distorted by a too-close lens or invent detail lost in shadow. Five habits that produce a convertible photo:

Pick a destination
Every destination also has its own dedicated page — the same converter plus that document's requirements, checks and answers in one place:

Questions
In the United States, yes — passport and visa prints are both 2 × 2 inches (51 × 51 mm). Elsewhere, no: the UK prints at 45 mm high by 35 mm wide, Schengen member states use 35 × 45 mm, and Canada uses 50 × 70 mm. “Passport size” means nothing until you name the country.
It depends on the portal, not the passport. The DS-160 accepts square JPEGs from 600 × 600 up to 1200 × 1200 pixels at 240 kB or less; the UK’s digital service wants at least 600 × 750 pixels; India’s OCI upload caps out at 900 × 900. There is no single pixel size — convert for the portal you are actually filing.
A phone photo, yes. An arm’s-length selfie is a gamble — a lens that close distorts facial proportions, and conversion fixes background, crop, and file size, not geometry. Hand the phone to someone else, step back from the wall, and face the light.
It is the standard for the UK, for Schengen member states, and for many other countries — but not a universal one. The US and India’s OCI use 2 × 2 inches, Canada uses 50 × 70 mm, and Australia publishes a range of 35–40 mm wide by 45–50 mm high, of which 35 × 45 is only the smallest accepted print.
Because dimensions were probably never the problem. A resize cannot move your head inside the required band, lift your eye line, or repaint a shadowed or coloured background — and the portal’s file window is a separate rule again. A free compliance report on the photo as-is will name the failing measurement instead of leaving you guessing.
