ID Photo Maker

📖 What this does

One application wants a blue one-inch photo, social security wants white, the visa form wants yet another size, and each round of changes costs you half a day. This does the recolour and the crop in one pass. Upload a photo and it samples the four corners to work out what the background is, removes pixels close enough to that colour, lays down the colour you chose, then crops to one inch, two inch, visa and the rest before handing you a file. When the cutout is rough, nudge the tolerance and the feather - a little feather around hair looks far more natural than a hard edge.

✨ Features

• Background swapping is chroma keying off a corner sample: average the four corners to get the background colour, judge every pixel by weighted colour distance, then cut within the tolerance and feather the boundary.
• Ten size presets - one inch, small one inch, large one inch, two inch, small two inch, visa, social security, US visa, square - or type your own width and height. The equivalent millimetres at 300 dpi update underneath.
• Besides white, blue, red and grey you can pick any colour. The gradient option lays down a blue-to-white vertical fade, which some visa photos expect.
• Scale and position are separate: the scale slider sets how much of the frame the head fills, and dragging on the preview moves the photo around, so you are not locked to a fixed template.
• Export as JPG or PNG at one, two or three times size. One inch at 2x comes out 590x826, which gives a print shop more to work with than the bare spec.
• Everything happens in the browser. The photo is not uploaded and nothing is written to an account.

🛠 How to use it

1. Press Choose photo or drop a file on the dashed box. A head-on shot with even light and a plain background gives the best cutout.
2. Click a size preset, or type your own width and height. The line below shows what that works out to in millimetres at 300 dpi.
3. Pick a background colour. White, blue and red have buttons; anything else uses the colour picker. If the cutout is making things worse, untick the automatic removal and the tool will only lay down a colour without cutting anything away.
4. Adjust tolerance and feather: raise tolerance when old background survives, raise feather when you see jagged edges around hair. Then drag the preview to straighten the framing.
5. Choose a format and export scale, then press Download photo. Use Copy image when you need to paste it into a form.

⚠️ Before you rely on it

• Plain backgrounds only. Patterns, furniture or other people behind you will get eaten by the keying along with the backdrop. Those photos need a proper cutout tool first.
• Clothing close to the background gets holes. A white shirt on a white background, or a navy suit on blue, will develop gaps at the edges. Wear something with clear contrast and reshoot.
• Trust the receiving organisation, not the preset. Pixel definitions of one inch and two inch differ between authorities, and social security and visa sizes change from time to time. Check the current official requirement before submitting.
• PNG only buys you something if you skip the fill. A filled background is fully opaque. For a transparent result you need a dedicated cutout tool; what this exports is a finished photo on a colour.
• Large photos take a moment. Phone originals run four or five thousand pixels across, and per-pixel keying takes a few seconds during which the page stops responding. That is expected.
