Why do it in the browser at all?
Your ID never travels
A passport photo, a signature and a date of birth are the three things an identity thief needs. Most free resizers upload all three to a server you know nothing about. Here the file is opened by the page itself and the pixels stay in your tab.
Exact, not approximate
“Compress” is not a number. FileKB runs a real search over encoder quality until the file lands inside the window you typed — and tells you honestly when a target is impossible.
No queue, no watermark
No upload progress bar, no waiting room, no “3 free files per day”. Your own processor does the work, so a batch of fifty photos takes seconds.
Ready-made settings

Start from the error message
An upload fails for one of four reasons: the file weighs too much, it weighs too little, its pixel dimensions are wrong, or its format is not accepted. Read the portal's exact sentence, pick the matching tool, and fix that one thing. Chasing all four at once is how an afternoon disappears.
What makes this different from the usual resizer
Two things. First, the minimum-KB field is a normal control here, not an afterthought, because half of all Indian form rules are windows — ten to twenty kilobytes, twenty to fifty kilobytes — and a tool that only respects the ceiling will happily hand you a file the portal calls too small.
Second, every exam and document page cites the notice it took its numbers from, with the document title and the date we read it. Where a commission publishes nothing, we say so instead of repeating a figure that has been copied between websites for a decade. That is why the Staff Selection Commission page tells you there is no photograph size to hit, and why the Aadhaar page tells you no photograph upload exists at all.
Nothing is uploaded, and that is verifiable
Files are decoded, redrawn and re-encoded by your own browser. There is no server endpoint to send them to, no account, and no queue. Load the page once, switch off your data connection, and every tool keeps working — which is the simplest proof available that your identity documents are not travelling anywhere.
How it works
- Choose the file. Drop a photo, signature or PDF, or tap to pick it from your phone. It stays on your device.
- Set what the form asks for. Type the KB limit and, if given, the width × height in px, cm or inch — or open an exam preset that fills them in.
- Download the verified result. The tool shows the final size and dimensions before you save, so the upload is accepted first time.
