    How the RRB NTPC signature spec compares

    We track a signature specification for 14 exams. The RRB NTPC box is 140×60 px — about 2.3 times wider than it is tall, which is why a square crop of a signature almost always gets rejected here even when the file size is right. 9 other exams in the set use the same box: NEET, JEE Main, SSC, GATE, IBPS / Bank PO, SBI exams, CUET, UGC NET, TNPSC. A signature prepared for one of those is dimensionally ready for this one.

    The 30–49 KB file-size band is tighter than 5 of the exams we track and looser than 8 of them. Note that it sets a minimum of 30 KB as well as a maximum. Compressing below the floor is rejected exactly like exceeding the ceiling, so aim for the middle of the band rather than the smallest file you can produce.

    Disclaimer: the official RRB NTPC notice always overrides these prep targets.

    Frequently asked questions

    What size should my RRB NTPC signature be?

    Common prep target: 140×60 px and 30–49 KB JPG on a white background. Confirm the current RRB NTPC notice — rules change by year.

    How does white-background cleanup work?

    The tool thresholds dark ink onto pure white in your browser so scanned signatures look portal-ready. The image is not uploaded to our servers for processing.

    Is my signature uploaded?

    No. TryQuickImg processes the image locally — not uploaded to our servers for processing. After the page loads you can go offline and still finish.

    Where this spec comes from

    These figures are commonly-cited ranges, read from the official notice by hand and re-checked on a set date — nothing here is scraped, so a number never changes without a person confirming it. The notice for your own exam year always wins.
