ID Photo Resizer

Registration portals, staff directories and ID card systems tend to ask for a headshot at a fixed pixel size such as 300×400 or 413×531. Feeding them an unresized 12-megapixel phone photo means the system crops it however it likes. Setting the dimensions yourself keeps the framing under your control and produces a much smaller file at the same time.

Frequently asked questions

What's the difference between this and the passport resizer?

The passport tool is preset to official document standards measured in millimetres. This one is for the arbitrary pixel sizes portals and card systems invent — 300×400 and similar — where there is no printing standard behind the number.

Will cropping to fill cut off part of my head?

It can if the source photo has a very different aspect ratio, because filling the frame means trimming the longer side. Crop the photo roughly to the right shape first with the Crop Image tool if you want precise control over what is kept.

Should I upscale a small photo to reach the required size?

Avoid it. Enlarging invents pixels and the result looks soft, which reviewers notice on faces. Start from the largest original you have.

Is my document or ID photo uploaded anywhere?

No. The image is decoded and re-drawn entirely inside your browser with the Canvas API. Nothing is sent to a server, nothing is stored, and closing the tab discards everything.
