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

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.
