Frequently asked questions
+−What is the photo size for RRB NTPC?
The RRB Non-Technical Popular Categories application requires a photo of exactly 320×240 pixels, between 20KB and 50KB, in JPG format, on a white background.
+−How do I compress my RRB NTPC photo to under 50KB?
Drop your photo into the tool above. It pre-locks the dimensions to 320×240px and runs binary search across quality levels to land within 5% of your target size. The output downloads as JPG.
+−Will my photo be uploaded to your server?
No. Compression runs entirely in your browser using the Canvas API. Your photos never leave your device — useful for sensitive ID documents.
+−What if my original photo is too small or too low resolution?
If your source is under 320px wide, the tool will upscale (which can look slightly blurry). For best results, start with a photo at least 640×480 pixels and let the tool downscale.
+−Can I use this for the RRB NTPC signature scan too?
This page is calibrated for the photo. For signature scanning, use the main image compressor at https://wrrk.space/image-compressor with target-KB mode set to your signature's required size (typically 4-30KB).
+−Is the photo format requirement strict?
Yes — Railway Recruitment Board rejects applications where the photo doesn't match the exact specs. The tool ensures your output is JPG, 320×240px, and 20-50KB before download.
+−Where do I upload the photo after compressing?
Upload it on the RRB NTPC application portal at https://indianrailways.gov.in. We are not affiliated with Railway Recruitment Board; this tool just helps you meet the technical photo spec.
