How to Compress Railway Exam Photo to 20–40 KB Free Online
The 20–40 KB window is very narrow — phone photos are typically 2–5 MB, far above the limit. Standard image editors guess at quality settings and often miss the target. PhotoFit uses a binary-search algorithm to converge on your exact KB target: type 35 (leaving 5 KB margin below the 40 KB cap), upload, download. Done in under 30 seconds.
Also use the Resize tab to set dimensions to 100×120 px if your photo is not already that size. RRB portals check both dimension and file size separately — both must be within spec for the upload to succeed.
