Resize your photo or signature
Most forms state a limit in kilobytes, and most resizers only give you a quality slider. Enter the KB range your form asks for and this finds the setting that lands inside it.
Your image never leaves this device. It is read by your browser, resized on this page, and handed straight back to you. There is no upload and no server involved.

These are the sizes most forms ask for, offered as a starting point. Always use the numbers printed on the form you are filling in. They vary between departments.
Leave blank if your form does not state a limit.

Before After
Is my photo uploaded anywhere?
No. The file is read by your browser and changed on this page. There is no server, no account, and once the page has loaded it works with no internet connection at all. You are entitled to know that before handing over a photograph of your own face.
What is KB, and why do forms fail on it?
KB means kilobytes, how much the file weighs. Portals routinely demand a photo between 20 and 50 KB. Most resizers offer you "quality 60%" instead, which tells you nothing about the weight, so people export and re-upload until one is accepted. This tool works the other way round: you state the KB, it picks the quality.
What is the difference between crop and stretch?
If your image is not the shape being asked for, something has to give: either the edges are trimmed or the picture is pulled out of shape. Cropping keeps a face in proportion; stretching squashes it, and some portals reject that. Cropping is the default for that reason.
It will not go under the limit. What now?
Below a certain point the pixels themselves are the floor, and the tool tells you the smallest it managed rather than pretending. Reduce the width and height, fewer pixels is the only thing that will bring the file size down further.
Should I choose JPG or PNG?
Choose JPG if your form states a KB limit. PNG has no quality setting to trade against file size, so it cannot be tuned to a target. Nearly every government form accepts JPG.
