RRB NTPC photo resizer
Summary: this RRB tool crops, resizes and compresses your files 100% locally in your browser. Nothing is uploaded to a server, so your photo and signature stay private on your device.
Railway Recruitment Board applications for NTPC, ALP and Group D take a photograph of exactly 320 × 240 pixels, saved between 20 KB and 50 KB. The 50 KB ceiling is tight for a modern phone photo, and the fixed pixel size means a plain resize can stretch your face. This tool crops to the right shape first, resizes, and then finds the highest JPG quality that stays inside the 20–50 KB window.

Step-by-Step Guide for RRB Photo Uploads
- 1Take a recent colour photo against a plain, light background.
- 2Upload it here; the tool crops and resizes it to 320 × 240 px.
- 3Press Prepare and check the result panel shows a size between 20 KB and 50 KB.
- 4Download the JPG and upload it in your RRB application.
Preparing each file properly
What the numbers mean
A requirement like "200 × 230 px, 20–50 KB" sets two separate limits. The pixel size is the shape and detail of the image; the KB range is how many bytes the saved file takes. You fix the pixels first, then adjust compression until the file lands inside the range. A file can have the right pixels and still be rejected for being too small in KB, so check both values in the result panel.
Taking the photo
Stand facing a window or another even light source against a plain, light wall. Hold the phone at eye level about an arm's length away so the face is not distorted. Avoid caps, dark glasses and heavy shadows. Use a recent photo — the RRB notification states what "recent" means and what background is accepted.
Cropping correctly
The resizer crops to fill the required shape from the centre. If your face is not near the middle of the original, first crop it with the Crop Image tool so that the head and top of the shoulders are centred with a little space above the hair. For signatures and handwritten text, crop tightly around the ink so it is not lost in empty paper.
Resizing and reducing file size
Choose the tab for the document, upload it, and the tool resizes to the stated pixels and searches JPG quality until the measured size fits. Small images such as signatures often come out below the minimum KB. If that happens, start from a sharper, higher-resolution scan rather than adding noise — and check whether the current notification really sets a minimum.
Keeping quality acceptable
Zoom into the preview before downloading. Faces should look natural, not blocky, and every letter of a signature or declaration should be readable. Always work from the original photo rather than re-compressing a file you already compressed, because each save loses detail.
Troubleshooting
- Portal says the format is wrong: download the JPG from this page; do not rename a PNG or HEIC file. iPhone photos can be converted with HEIC to JPG.
- Image looks stretched: you used a custom size with a different ratio — use the document tab's preset.
- Upload fails with no message: check the file name has no special characters and try another browser.
- Photo too dark after compression: retake it in better light; compression cannot recover lost detail.
The official RRB recruitment notification and the instructions on the application portal are the final authority. Requirements can change between recruitment cycles, so confirm the current values there before you upload. TryImager is not affiliated with RRB.
Common rejection reasons
- Pixel size is not exactly 320 × 240.
- File is above 50 KB or below 20 KB.
- Photo is blurred, dark or heavily filtered.
Frequently asked questions
What is the RRB NTPC photo size?
320 × 240 pixels, between 20 KB and 50 KB, in JPG. The same rule is used for ALP and Group D applications.
Why is my RRB photo under 20 KB?
At 320 × 240 px a plain photo can compress very small. Use the original camera photo rather than a forwarded or screenshot copy; more real detail gives a larger file at high quality.
Will my face look stretched?
No. The tool crops the photo to the 320 × 240 shape from the centre before resizing, so proportions are kept.
Can I do this on my phone?
Yes. The page works in mobile browsers, and the file is processed on the phone itself.
Is my photo stored anywhere?
No. It never leaves your browser; the finished JPG downloads straight to your device.
