What size does the RRB Railway photo need to be
The RRB Railway form wants the photo at 320 by 240 pixels, saved as a JPG, with the file somewhere between 15 and 40 KB. At 300 DPI that works out to roughly 2.7 by 2.0 cm on paper. All three conditions have to hold at once. Getting the pixels right will not help if the file is the wrong weight, and a file of the right weight fails if the dimensions are off. The portal checks each one separately and the error message it shows rarely tells you which one failed.
What the shape means for cropping
320 by 240 pixels is a ratio of 4:3, which is wider than it is tall. The target is wider than it is tall while a phone photo is the other way round. Cropping to fill will take a fair amount off the top and bottom, so check the important part sits inside the frame before you download. Open More controls above if you want to switch between cropping the edges to fill the frame and keeping the whole image with white space around it.
Why the range is 15 to 40 KB
People tend to read only the upper limit and compress the file as small as it will go. That is the single most common mistake. A file under 15 KB is rejected exactly as firmly as one over 40 KB, because the portal tests both ends. This tool searches for the best quality that still fits under 40 KB, and if the result lands below 15 KB it lifts the file back into range without altering a single pixel. There is plenty of room at this size, so quality barely has to drop at all.
How to do it
Tap the box above and pick your image. The preset is already set to RRB Railway photo, so the width, height and KB range are filled in and you do not need to type anything. Press Resize. The result appears below with a three line checklist covering pixel size, file size and format. Green against all three means the portal will accept it. Then press Download JPG and upload that file to the form.
Doing it on a phone
Tap the box, pick the shot from your gallery, and the finished file lands in Downloads ready to upload. Use the rear camera rather than the front one, since the selfie lens distorts a face at close range. Worth knowing: phone cameras do not rotate the picture, they store the rotation in a hidden tag. That is why a photo looks upright in your gallery and arrives sideways at the portal. This tool reads the tag and straightens it on the way through.
What your original needs to be
The target here has a long edge of 320 pixels. Anything from a phone camera in the last decade is far bigger than that, so you have room to spare. Aim for an original with a long edge of at least 640 pixels and the result stays sharp. What you must avoid is feeding in something already smaller than 320 by 240, because scaling an image up cannot invent detail that was never captured. That is why a crop from a group photo, or a screenshot, tends to look soft no matter what you do to it afterwards.
Which exams this covers
These dimensions apply across NTPC, Group D, ALP. The bodies running them keep the photo specification consistent between its papers, so one correctly sized file usually serves every form you fill under it that season. Save the 320 by 240 version you download here and you can reuse it, but check each notification anyway, because a single paper occasionally departs from the standard.
What the photograph should look like
Face the camera straight on with your eyes open and your whole face visible. Keep the background plain and light. White, pale blue or light grey are the safest choices. No cap and no sunglasses. Prescription glasses are usually fine as long as there is no glare on the lenses. Leave a little space above your head, because a tight frame means the crop will cut into your forehead. Many exams now ask for the date to be printed on the photograph and for it to have been taken recently, often within the last three or six months, so check your notification.
Photos that will not work
A selfie is often rejected because the lens stretches the edges of the face. A picture cropped out of a group photo comes through soft and blurred. Anything sent over WhatsApp has already been compressed once, so use the original file from your gallery instead. A screenshot of a photo loses a great deal of quality and rarely passes.
If the upload is still rejected
Read your notification again and check the numbers against this page. Exam bodies revise them between cycles, and the 320 by 240 px and 15 to 40 KB shown here reflect a previous notification. If your notice says something different, type those numbers straight into the width, height and KB boxes above, which are all editable. If it still fails after that, try a different browser, and try renaming the file. Some portals quietly reject file names containing spaces or special characters.
