Make a Passport or ID Photo to Exact Size

The requirement you pick fills every field, so a file lands already configured; the fields sit under the drop zone for checking or for a custom size. The frame is the one thing that waits for a photo to exist, because a crop means nothing until there is a picture to measure it against.

1. Pick a verified requirement, or Custom. The chips above the drop zone are four checked sources plus Custom. Choosing one fills the size, format, DPI and any file-size limit it publishes; Custom leaves every field for you to set.
2. Check the fields it filled in. Width, Height, Unit, DPI, Output format and the file-size limits sit under the drop zone, filled in from the requirement rather than from the photo. Edit any of them and the page switches to a custom size.
3. Drop your photo, or try the sample. JPEG, PNG or WebP, up to 20 MB. No photo to hand yet? Try the sample — a generated scene, not a real person — to see the whole flow first.
4. Position the frame over the head. A fixed box appears at the target shape, with a head-height band when the requirement publishes one. Drag, zoom or use the arrow keys to choose which part of the photo is kept.
5. Press Make photo. The crop, the resize, the format and the byte search all run in this pass. A file-size limit can take a few extra seconds while the button reads Finding the size.
6. Read the checklist, then Download photo. Every check Resizo can run — dimensions, format, file size, DPI — is listed with what was required, what the file actually has, and Meets or Fails in words. Photographic rules Resizo cannot check are listed underneath, followed by the source and the day it was checked.

One measured run, on the generated portrait the page offers as a sample. The United States printed preset asked for 2 × 2 inches at 300 DPI, which is 600 × 600 pixels; the tool cropped the 3:4 source to a square around the frame, resampled it, wrote the DPI record and checked the result.

Before

After

Four requirements, read from the issuing authority’s own page and checked on the date shown. Pixel figures for a physical size are worked out at 300 DPI, which is Resizo’s own choice for a photo print — none of them names a resolution — and changing DPI on this page changes the pixel target the same way.

The pixel arithmetic behind each physical size, in full:

• UK passport photo (digital, 600 × 750 px): Stated directly in pixels by the authority — no DPI arithmetic involved.
• UK passport photo (printed 45 × 35 mm): 35 mm × 300 DPI ÷ 25.4 = 413 px wide; 45 mm × 300 DPI ÷ 25.4 = 531 px tall
• US passport photo (printed 2 × 2 in): 2 in × 300 DPI = 600 px wide; 2 in × 300 DPI = 600 px tall
• India passport photo (pasted 4.5 × 3.5 cm): 3.5 cm × 10 ÷ 25.4 × 300 DPI = 413 px wide; 4.5 cm × 10 ÷ 25.4 × 300 DPI = 531 px tall

  • Photograph is NOT REQUIRED for applications submitted at Passport Seva Kendra (PSK), Post Office Passport Seva Kendra (POPSK).
  • Photograph should be printed on good quality photo paper.
  • Photograph in computer print will not be accepted.

Everything below the fold on this page is mechanical: a pixel count, a byte count, a format tag and a DPI field are all things Resizo can read back out of the file it just wrote and compare against a number. Nothing about a face is mechanical in that way, so none of it is checked here.

Resizo can enforce:

• The exact pixel width and height, and the aspect ratio that implies.
• The output format — JPEG or PNG.
• A maximum file size, and, in Custom mode, a minimum.
• A DPI record, written into the file and read back to confirm it landed.

Resizo cannot verify pose, facial expression, lighting or shadows, red-eye, whether the real backdrop in your photo is the colour or texture asked for, how recently the photo was taken, or whether the issuing authority will accept the finished file. Each requirement’s own wording for the rules it cannot check:

An authority that publishes a size on paper — millimetres or inches — is describing a print, not a file, and a print has no pixel count until a resolution is also chosen. The same 35 mm is 413 pixels at 300 DPI and 138 pixels at 100 DPI; a form that states “35 mm” is not silently also stating a pixel count.

Resizo uses the formula every printer uses — millimetres ÷ 25.4 × DPI, rounded to the nearest whole pixel — shown in full for every physical preset above. 300 DPI is Resizo’s own choice for the presets, the resolution photo labs print at; no source on this page names one. Changing DPI here changes only the pixel target, never the physical size a preset states. Need the same arithmetic without cropping a photo? Change image DPI does the conversion on its own.

Canada is the clearest case, so it is named rather than left as a silent gap. Immigration, Refugees and Citizenship Canada requires a printed photo “taken in person by a commercial photographer or photo studio”, and a digital photo for an online renewal has to be “saved directly from the original file captured by the camera”, with any alteration rejected. Resizo’s output is cropped, resized and re-encoded on your device by definition, so neither Canadian route can be met by a file this tool writes — no Canadian preset is offered here rather than one that would only fail at submission. (Immigration, Refugees and Citizenship Canada, Photos for Canadian passports, a page dated February 11, 2026 and read on September 10, 2026.)

The same test applies beyond Canada: a country whose rule requires an unaltered original file straight from a camera, or a photograph taken in person by a professional, is a country no cropping-and-resizing tool can serve, and a preset is added here only once a route exists that a file Resizo writes can actually satisfy.
