RRB signature

JPEGAt least 140 × 60 pixels30 KB to 49 KB

RRB's CEN 09/2025 asks for a signature JPEG between 30 KB and 49 KB, at least 140 x 60 pixels. A clean signature is far smaller than 30 KB, so it is padded up to the minimum without changing it.

Getting an RRB signature to 30 KB to 49 KB

RRB's Centralised Employment Notification 09/2025 asks for a scanned signature, in running handwriting in black ink on white paper, as a JPG or JPEG between 30 KB and 49 KB and at least 140 x 60 pixels.

The form places the signature in a 35 x 20 mm box, so this page makes it 350 x 200 pixels, the same shape and well above the minimum. It is saved at the best quality under 49 KB, and because a signature at that size is usually well under 30 KB, it is padded up to 30 KB with an invisible comment inside the file. The signature is exactly the same.

Tips

  • Sign in running (joined-up) handwriting. The notice rejects block, capital or disjointed letters.
  • Take the photo close around the signature, then drag the crop box so it keeps all of it.
  • Each notification sets its own rules. The RRB photo is captured live in the application, so there is no photo to upload.

Requirements from RRB Centralised Employment Notification 09/2025, checked 26 September 2026. Forms change their rules, so check the form itself if something is rejected.

How it works

  1. 1

    Drop your file

    A PDF or an image. It goes over an encrypted connection and nowhere else.

  2. 2

    Pick your limit

    Choose the size the form asks for. We start with a cleanup that changes nothing you can see.

  3. 3

    Download it

    If it needs more, we find the gentlest quality setting that still fits, and delete everything soon after.

Questions

Is it free?

Yes. There is no sign-up and no watermark.

What happens to my file?

It is processed on our server and deleted automatically: the original 5 minutes after the run finishes, the compressed file after 10. A file you upload but never compress is deleted within 30 minutes. You can also delete everything right away with Delete now.

Will it look worse?

We try a lossless cleanup first, which does not change how the file looks. Only if that is not enough do we lower image quality, and we pick the gentlest setting that still fits your size.

What if my file cannot get that small?

You get the smallest version we could make and a clear note saying so, instead of a file that silently misses the limit.

Why does the size page aim a little under its limit?

Some sites count a kilobyte as 1000 bytes and others as 1024. We aim under the stricter one, so a 200 KB page aims for 200,000 bytes and the file passes either way.
