Crop and rotate a photo

Pixels, centimetres and the dpi that connects them

A form can express the same requirement in three languages. Some portals print pixels, some print centimetres, some print inches, and a few print all three with numbers that do not agree. The bridge is dots per inch. A 3.5 x 4.5 cm passport photo is 138 x 177 px at 100 dpi, 276 x 354 px at 200 dpi, and 413 x 531 px at 300 dpi. None of those is wrong; they answer different questions. When a portal states both a cm size and a pixel size, obey the pixel size, because that is what its uploader measures.

Ratio lock is the feature that protects your face

The quickest way to fail a photo check is a distorted face, and distortion is what happens when a 4:3 camera frame is forced into a 1:1 box by squashing. This tool never does that. You give it a target, it locks the crop frame to the same shape, and you decide what stays inside the frame. The export is a genuine crop followed by a proportional resample.

Composition rules that verifiers actually check

Head height should occupy roughly two-thirds to three-quarters of the frame, with a small margin of space above the hair. Eyes should sit a little above the vertical middle. The face must be square to the camera, both ears roughly visible, mouth closed, eyes open, no cap, no dark glasses. Indian visa and passport instructions add specific numbers — the Indian e-Visa guidance asks for a square photograph with the head between twenty-five and thirty-five millimetres of the frame height, and no borders or shadows. The document pages on FileKB quote each portal's own wording with a link, so you can check rather than guess.

Straightening a document scan

Phone photographs of paper are almost always slightly rotated, and a tilted signature or certificate looks careless next to a properly aligned one. The rotate dial moves in single degrees with a live grid, which is enough to fix the two or three degrees of tilt that a hand-held shot picks up. Rotating slightly re-samples the picture, so do the rotation before you spend your quality budget on compression.

Common pixel boxes and where they come from

The 200 x 230 photograph and 140 x 60 signature pair is the banking family: IBPS and SBI recruitment guidelines print exactly those figures. 350 x 350 as a minimum with a square shape comes from the Indian visa flow. 600 x 600 is the United States non-immigrant visa photo, which is square and much larger than anything Indian portals ask for. Round numbers such as 300 x 300 and 400 x 400 mostly circulate on resizer websites rather than in official notices, which is why FileKB routes those to this tool instead of publishing a page that claims an official source it does not have.

Working with a mirrored selfie

Front cameras on most phones save a mirrored image. A mirrored face is not usually a rejection reason, but mirrored text is — a photographed marksheet or an ID card held up to the camera can come out reversed. The flip control fixes it in one click, and the preview makes the problem obvious before you upload.

Check the export, not the preview

A crop frame on screen is a promise; the exported file is the result. Open the downloaded image and confirm the width and height are exactly what you typed, because some portals compare the dimensions to the digit and will refuse a file that is one pixel out. It takes five seconds and it saves the round trip.

Then hand the file on

This page controls geometry only. Once the crop is right, pass the file to the KB tool if a size window applies, to the name-and-date tool if the form wants captions burned into the image, or to the photo-to-PDF tool if the portal insists on a PDF. Doing the steps in that order means you never have to repeat one.
