What is the correct size for a passport size photo?
On paper, 35 × 45 mm — which notices usually word as 3.5 × 4.5 cm. Online forms additionally state a pixel size and a KB limit, and those differ by portal: many Assam portals want 200 × 230 pixels, and SSC asks for 3.5 × 4.5 cm at 20–50 KB. Pick the standard here that matches your notice; the notice is the authority.
How do I get my photo under 50 KB?
Enter 50 in the size limit box before pressing the button. The photo is cropped to the exact pixel size first, then re-encoded as a JPG at progressively lower quality until it fits. The pixel size never changes while it does this — a 200 × 230 photo stays 200 × 230, because a portal that asks for those dimensions rejects anything else however few kilobytes it is. If the limit still cannot be met the tool says so plainly rather than handing you a file that will bounce; a plainer, less detailed background usually compresses much further.
Can I use a normal phone photo?
Yes, and that is what this is for. Take it against a plain light-coloured wall in even daylight, facing the camera straight on, then crop it here. What this tool will not do is change your background, add a border or retouch anything — it crops, resizes and compresses, and it says plainly when a photo is too small to fill the size you asked for.
Why does it warn that my photo will look soft?
Because the part of the photo you cropped has fewer pixels than the output size needs, so it has to be enlarged — and enlarging adds no detail. Zoom out to include more of the original photo, or start from a larger one. A soft, blocky photo can be rejected at document verification even after the upload succeeds.
Does it work for a signature too?
Yes. Choose the Signature standard, which crops to a wide 140 × 60 pixel box at a 20 KB ceiling. Sign in black ink on white paper, photograph it in good light, and crop to the signature itself. Transparent areas are filled with white, so a PNG signature will not come out with a black background.
Why is the Assam portal size 200 × 230 and not 35 × 45 mm?
Because they are two different shapes and both are real. 35 × 45 mm is how a notice words a passport size photograph in prose; 200 × 230 pixels is what many Assam portals enforce in the upload box, and it is very slightly wider. Where the two disagree the upload box wins, so the APSC option here crops to 200 × 230 exactly. Match your notice: if it names a pixel size, that is the one that decides whether the form accepts your file.
Can I change the background to white or blue?
No, and it is worth saying so plainly rather than pretending otherwise. This tool crops, resizes and compresses — it does not cut you out of your background or replace it. Transparent areas in a PNG are filled with white so a signature does not come out on black, but that is the only colour it touches. Photograph yourself against a plain, light, evenly lit wall and the crop is all you need.
Is my photo uploaded anywhere?
No. The cropping and compression happen inside your browser using your own device, so the photo never leaves your phone and there is no server to receive it. Closing the page is enough to be rid of it.
