Why exam photo specs are so strict

Indian government portals use automated image verification systems that reject uploads failing even by a few pixels or kilobytes. SSC typically requires 200×230 pixels under 50 KB; UPSC asks for 350×350 pixels up to 300 KB; RRB NTPC uses 320×240. A rejected form during application season can cost you an entire exam cycle.

How this tool works

We use high-quality Lanczos resampling to resize your image to the exact pixel target, then binary-search JPEG quality to land inside the file-size window. Images are fitted onto a clean white background automatically — no transparent edges, no aspect ratio surprises. The entire pipeline runs in your browser using JavaScript and the HTML Canvas API.

Four steps: resize to the exact pixels, fit on a plain white background, tune the JPEG quality, download inside the KB window1Resizeto the exact pixels2Fit on whiteplain white edges3Tune qualityJPEG quality search4Downloadinside the KB window
These steps run in your browser when you press resize.

Frequently asked questions

Which exams does the photo resizer have presets for?
20+ Indian government exams — SSC CGL/CHSL/GD, UPSC CSE/NDA/CDS, IBPS PO/Clerk, SBI PO/Clerk, RRB NTPC/Group D/ALP, NEET UG, JEE Main, CTET and more. Pick your exam from the dropdown and the exact pixel dimensions and KB limits are applied automatically.
Can it resize a signature as well as a photo?
Yes — switch to signature mode and the tool applies your exam's signature spec (for example 140×60 pixels) instead of the photo spec.
How does it hit an exact file size like 20–50 KB?
It resizes to the exact pixel dimensions first, then adjusts JPG quality until the file lands inside the allowed KB range — so the output passes both the dimension and file-size checks on the application portal.
Is my photo uploaded to a server?
No. The entire tool runs in your browser — your photo and signature never leave your device, and nothing is stored or logged.
