Is my passport photo uploaded to a server?

No. Cropping, background replacement and layout all use the browser's canvas API, and the photo never leaves the device. Turning off the network after the page loads does not stop the tool working.

Why does the background replacement fail on some photos?

It removes background by colour, so it needs the original backdrop to be reasonably uniform. Against a busy or patterned background no single colour describes the backdrop, and any threshold that removed it would also remove matching parts of the subject. That case needs a segmentation model.

What pixel size is a passport photo at 300 dpi?

A 35 x 45 mm photo is 413 x 531 pixels at 300 dpi. A 2 x 2 inch US passport photo is 600 x 600 pixels. A 25 x 35 mm China ID photo is 295 x 413 pixels.

How much of the photo should the head fill?

Most authorities ask for head height to be 60 to 70 percent of the photo height, with the US specifying 50 to 69 percent. The eye line typically sits 30 to 50 percent down from the top edge. The tool overlays guides for both bands.

Can I print passport photos at home?

Yes, and a 4 x 6 inch sheet holds several copies. Print at actual size with no scaling, since fit-to-page changes the dimensions by a few percent, which is enough to fail a measurement check. Trim slightly inside the printed frame.

Make an ID or passport photo

Crop a photo to a documented passport, visa or ID size at 300 dpi, replace the background with the colour the authority asks for, and lay copies out on a 4×6 sheet if you want to print them. Everything happens on your own device.

Document

Background colour

Zoom — 100%

Replace the existing background. Measures the colour around the edges of your photo and removes it, so a photo taken against a wall can become pure white or blue. Turn off if the background is already correct. Show framing guides. Marks the head-height and eye-line range that most authorities work to.

Drag the photo to position it. Use the zoom slider to size it.

Your photo stays on your device. Cropping, background replacement and layout are all done with the browser's canvas API. Nothing is uploaded. Re-encoding drops EXIF data, which for a passport photo is usually what you want.

Sizes for common documents

These are the printed sizes, converted to pixels at 300 dpi — the resolution most photo printing and online submission systems expect. Dimensions are the finished photo, not the size of the subject within it.

Document	Printed size	Pixels @300dpi	Background
China ID photo, 1 inch	25 × 35 mm	295 × 413	White
China ID photo, 2 inch	35 × 49 mm	413 × 579	White
China passport	33 × 48 mm	390 × 567	White
US passport / visa	2 × 2 in	600 × 600	White
UK passport	35 × 45 mm	413 × 531	Light grey
Schengen visa	35 × 45 mm	413 × 531	Light grey
Japan passport	35 × 45 mm	413 × 531	White
India passport	2 × 2 in	600 × 600	White
Canada passport	50 × 70 mm	591 × 827	White
Australia passport	35 × 45 mm	413 × 531	White

Always check the current requirement for your specific document before submitting. Authorities revise specifications, and some consulates want a size or background that differs from the national standard. The list here is a starting point, not an authority.

Framing: the part that actually causes rejections

Getting the pixel dimensions right is the easy half. Most rejected photographs fail on framing, and the requirements are more precise than people expect.

The two figures that matter are head height (chin to top of head, as a proportion of the photo height) and eye position (how far down from the top edge the eyes sit). Different authorities specify different values, but they cluster:

Measure	Typical requirement
Head height	60–70% of the photo height for most passports; US passports ask for 50–69%
Eye line from the top	Roughly 30–50% down; the US specifies 56–69% from the bottom
Margins	Visible space above the head; shoulders included at the bottom
Head position	Facing the camera squarely; no tilt; mouth closed; eyes open and visible

Turn on the framing guides in the tool to see the head-height band and the eye-line band overlaid on your photo, then drag and zoom until the head sits inside both. It is a far quicker way to get it right than measuring pixels.

Photographing the source image

Starting from a good source matters more than any editing step. What the authorities check, in rough order of how often it causes a rejection:

Even, shadow-free lighting on the face. A window to one side produces a shadow across half the face. Face a window rather than standing beside one.
A plain background. A wall is ideal. Since this tool can replace the background, the wall does not need to be the right colour — it needs to be uniform, so the removal works cleanly.
No glasses if possible. Many authorities now refuse photographs with glasses, and those that allow them forbid glare and thick frames.
Neutral expression, mouth closed, eyes open. Some allow a natural smile; several explicitly do not. Neutral is always safe.
Stand far enough back. A phone at arm's length distorts facial proportions. Two metres away with digital zoom is usually better than thirty centimetres.
Shoot at the highest resolution available. A 300 dpi print of a 35 × 45 mm photo needs 413 × 531 pixels — small by modern standards, but starting from a larger original gives you room to crop and straighten.

Replacing the background

The tool measures the colour at the edges of your photo and removes pixels close to it, then fills the result with the colour you chose. It works on the same principle as the white background tool, and it shares the same limits honestly.

It works well when the original background is a flat, evenly lit surface — a painted wall, a bed sheet, a studio backdrop. It does not work on a busy background, and no amount of adjusting will fix that, because a colour-based method has nothing to measure.

Three things that make the difference between a clean result and an obvious edit:

Keep the edge clean. The tool reconstructs edge pixels rather than leaving a halo, but it works from what is in the photo. A source with a dark shadow behind the head is harder to rescue than a clean one.
Watch the hair. Wispy hair against a patterned background is where any automatic method struggles. A plain wall is not just tidier, it is measurably easier to process.
Do not over-smooth. Some automatic ID photo services apply heavy skin smoothing. Several authorities reject visibly retouched photographs, and the guidance generally asks for an unmodified likeness.

Printing at home

Photo labs and kiosks usually print a single photo per sheet and charge per print, but a 4 × 6 inch sheet holds several passport photos. The print sheet option lays copies out on a 1200 × 1800 pixel canvas at 300 dpi with a small gap between them, which you can take to any print shop that accepts a JPEG.

Two practical notes:

Ask for actual size, not "fit to page". Printers often scale to fill the paper, which changes the dimensions by a few percent — enough to fail a measurement check. Choose 4 × 6 inch, borderless if available, at 100%.
Cut with a margin. Trim slightly inside the printed frame rather than exactly on it, so no white border survives into the finished photo.

Questions

Is my photo uploaded to a server?

No. All processing uses the browser's canvas API and the file never leaves your device. Turn off your network after the page has loaded and the tool continues to work.

Why can it not handle a busy background?

Because it removes background by colour, not by understanding what is in the picture. If the backdrop varies, no single colour describes it, and any threshold that removes the backdrop would also remove matching parts of the subject. A segmentation model would be needed, and the accurate open models are licensed for non-commercial use only.

Can I use a selfie?

Sometimes, but a phone held at arm's length distorts the face, and several authorities refuse selfies outright. If you have no alternative, hold the phone further away and crop, rather than filling the frame from close up.

What resolution should the print sheet be?

300 dpi is the standard. A 4 × 6 inch sheet at that resolution is 1200 × 1800 pixels, which is what this tool produces. Higher resolution is not useful for a print shop; lower may be visible in the finished photo.

Does the tool check whether my photo complies?

No, and be sceptical of anything that claims to. It produces a correctly sized, correctly coloured photograph with framing guides to help you position the head. Whether the expression, lighting and pose meet a particular authority's rules is a judgement you have to make against that authority's published requirements.
