RRB Railway Photo Resize Tool – Resize Photo for NTPC, Group D, ALP & JE Forms
Every year, millions of candidates apply for Railway Recruitment Board exams including RRB NTPC, RRB Group D, RRB ALP, and RRB JE. One of the most common reasons an application gets flagged or rejected before it is even reviewed is a photo or signature that does not meet the file size specification. The RRB portal is strict — if your passport photo is larger than 50KB or your signature file is outside the 10KB to 40KB range, the form simply will not accept it.
This free RRB Railway Photo Resize tool handles both in one place. Upload your passport photo, pick a target size (20KB, 30KB, 40KB, or 50KB), and the tool compresses it to match while keeping the image as clear as possible. Switch to the Signature tab to do the same for your signature, with target sizes ranging from 10KB to 40KB. Both tabs download the result as a JPEG file ready to upload directly on the RRB application portal.
The tool works entirely in your browser. Your photo and signature are never sent to any external server, which means you do not have to worry about sensitive personal images being stored or misused. It works on Android phones, iPhones, tablets, and computers — no app installation required.
