Most Indian government job portals (including SSC CGL, CHSL, MTS, UPSC Civil Services, IBPS Banking, and Railway RRB) automatically reject application forms if your uploaded passport photo or signature falls outside strict file size (KB) or pixel boundaries.
Direct Answer: Select your target exam preset above (e.g. SSC Photo 20–50 KB), upload your photo from your phone or PC, and click download. Our browser engine uses real-time canvas compression to crop, scale, and compress your image to the exact allowed file size without sending your personal photos to any server.
