    About Signature Resize

    Online exam and job forms usually ask for a signature in a fixed pixel size and a KB range, such as 140 × 60 px and 10–20 KB. Take a photo of your signature on white paper and this tool trims the empty space, makes the paper white and the ink darker, then fits the size and KB range you enter.

    Rules differ between exams and change over time, so the boxes are editable. Always check the latest official notification for the exact size.

    When is it useful? When a portal rejects your signature because of its size in pixels or KB.

    Good to know: sign with a black or dark blue pen on plain white paper. If the result is smaller than the minimum KB, harmless filler data is added to the file so it meets the minimum; the picture does not change.

    Tips for Better Results

    • Sign with a black or dark blue pen on plain white paper.
    • Copy the pixel size and KB range exactly from the official notification.
    • Check the size shown before uploading — portals reject even 1 KB too much.

    Frequently Asked Questions

    What size does my exam need?
    It depends on the exam and year. Check the official notification; enter those numbers in the boxes.
    Why is filler data added?
    Some portals need a minimum KB. A small clean signature can be below it, so filler bytes are added without changing the picture.
    Can I use a phone photo?
    Yes. The tool removes the grey paper background and empty space.
    Why was my signature rejected for 1 KB?
    Portals are strict. Check the size shown before uploading.
    Works with: Government, exam, bank and job portals

    Signature Resize: a complete guide

    Why signature uploads fail so often

    Exam and job portals usually demand a signature picture in an exact pixel size and a KB range — for example 140 × 60 pixels and between 10 and 20 KB. A phone photo of a signature is too big, too grey, has lots of empty paper around it and is often rejected several times.

    What happens when you resize

    Take a clear photo or scan of your signature on white paper. The tool can remove the empty space around the signature and make the paper white and the ink darker. It then fits the signature into the width and height you enter and saves a JPG inside the minimum and maximum KB you type. If the file is smaller than the minimum, harmless filler data is added so it meets the minimum — the picture itself does not change.

    Getting the numbers right

    Rules differ between exams and change from year to year, so the boxes are editable and the values shown are only examples. Always copy the exact pixel size and KB range from the official notification of your exam or job.

    Common problems and how to fix them

    The signature looks broken or too thin: sign again with a darker pen and photograph it in good light. The ink looks grey: keep “Make paper white and ink darker” turned on. The signature is squashed: your signature's shape is very different from the required box — sign a little wider or narrower to match the shape.

    Good habits

    Sign with a black or dark blue pen on plain white paper, keep the original photo, and check the final pixel size and KB size before uploading.
