Resize an image to 100 KB

100 KB is one of the two most common ceilings on Indian exam and government portals, and it is almost never the only rule. IBPS wants a photograph at 200×230 px and 20–100 KB. UPSC wants a signature at 20–100 KB. A long list of state portals and university forms quote the same 100 KB figure and then add a pixel size underneath it. Miss either number and the upload is refused, sometimes without saying which one was wrong.

The good news is that 100 KB is comfortable. A 200×230 px photograph fits inside it at high quality with room to spare — the file only becomes hard when the picture is still at the size the phone shot it. A 4032×3024 photo carries about twelve million pixels; the form wants roughly forty-six thousand. Almost all of the work is throwing away the ones nobody asked for.

This is where other resizers get it wrong. Feed a popular one a 1400×1400 photo with a 100 KB target and it will hand back something far smaller than you asked for — it hit the file size by quietly discarding the dimensions. That file passes the size check and fails the form.

This tool holds the pixel size you typed and lowers image quality until the file fits underneath 100 KB. If your target is genuinely impossible at those dimensions, it says so and shows the closest it managed, instead of handing you something that looks fine and gets rejected.

And since every one of these is a passport photo, a signature or an ID scan, none of it leaves your machine. Open your browser's network tab and check: the page loads its own files, and when the result is ready it sends one empty request to this same domain so we can count that the tool worked. That is everything. No analytics vendor, no tracker, no third-party request of any kind, and nothing carrying your image. The page's security policy blocks this site from opening a connection to anywhere but itself, so your image could not be sent even if we wanted to — here is exactly how.

Portals mean at most 100 KB, and a file that lands exactly on 102,400 bytes is a coin flip depending on how the receiving system rounds. This tool targets a budget below the number you type and reports the size it actually reached, so you can see the margin rather than trust it.

If the form gives a range — 20–100 KB is the usual one — the lower bound matters too: a file that comes out at 8 KB can be rejected for being too small. The result table shows the final size of every file, so a result under the floor is visible before you upload it.
