Upload to the tool above. Pre-configured to 200×230px and under 50KB. Click Compress.
Check the output is between 20KB and 50KB — RRB portals also reject photos that are too small (under 20KB). Download and upload to your RRB zone portal.
Frequently Asked Questions
Does the RRB portal accept PNG photos?
No — RRB portals require JPEG/JPG format only. If you have a PNG photo, upload it to this tool and select JPEG output. The tool will convert and compress to the exact RRB specifications in one step.
What if my compressed photo is under 20KB?
RRB portals enforce a minimum size of 20KB. If your photo compresses below 20KB, increase the quality slider to 70–80% to get a larger file. The tool shows the output size before you download, so you can adjust before submitting.
