RRB NTPC photo & signature resizer

RRB NTPC and other Railway Recruitment Board exam forms are strict about upload sizes, and several past notifications have also asked for the applicant's name and the date to be visible on the photograph itself — a detail that catches people out because it is not obvious from the size limit alone. Set the preset you need and this tool handles the KB and pixel side of it.

How to use this tool

  1. Add your photo

    Drop the image onto the box, or tap it to pick a file — on a phone you can shoot a fresh photo straight from the camera.

  2. Choose the target size

    Pick one of the KB presets or type your own number, and add a pixel width and height if the form demands specific dimensions.

  3. Check and download

    The preview shows the compressed result and its exact size. If it looks right, download the JPEG and upload it to your form.

Questions people ask

What is the RRB NTPC photo size?

Most RRB CEN notifications, including NTPC, ask for a recent colour photograph between 20KB and 50KB and a signature between 10KB and 20KB, each at a set pixel size. Some cycles additionally require the applicant's name and the date the photo was taken to be printed on the image. Check your specific CEN notification, as railway recruitment cycles do vary this.

Does this tool add my name and date to the photo?

No — it only resizes and compresses. If your CEN notification asks for a name-and-date photograph, get that printed or written on the physical photo (or added with a camera app that stamps it) before you upload it here for resizing.

Is my photo uploaded to a server?

No. The resizing happens inside your own browser using the Canvas API, and this site has no upload endpoint at all. You can switch off your internet connection after the page loads and the tool still works.

Will resizing to a small KB size ruin my photo?

Quality does drop as the file gets smaller, but the tool searches for the highest JPEG quality that still fits your target instead of guessing. The preview shows exactly what you are about to download, so you can judge it before saving.

Can I set the pixel width and height as well as the KB size?

Yes. Enter a width and height and the photo is resized to those dimensions first, then compressed to your KB target. Leave them blank to keep the original proportions.

Does it work on a phone?

Yes. Tapping the drop zone opens your camera or gallery, and the download works the same way it does on a desktop. Most forms are filled on a phone, so the tool is built for that first.
