Compress your SSC photo and signature
Three steps. Both files in the same session — no separate photo and signature tools.
Upload both files
Drop the candidate photo and the signature scan onto Sukat at the same time. JPG, PNG, HEIC (iPhone), or WebP — all decode locally. There’s no separate signature workflow; both files queue together.
Crop and set JPG output
Photo: Crop to head-and-shoulders, plain white behind — click Remove Background if the original was indoors. Signature: crop tight to the ink so whitespace isn’t eating KB. Set output to JPEG for both — SSC explicitly requires .jpg.
Set 30 KB and 15 KB targets
Photo: target 30 KB (a safe value inside SSC’s 20–50 KB window). Signature: target 15 KB (safe inside 10–20 KB). Click Convert & Download; both files save locally as .jpg.
Which SSC exams use this format
Every Staff Selection Commission exam runs on the OTR (One-Time Registration) photo + signature pair. Tighter caps than UPSC, identical workflow across exams:
- SSC CGL (Combined Graduate Level). The flagship Group B and C central-government exam — Income Tax Inspector, Assistant Section Officer, Auditor, and similar posts.
- SSC CHSL (Combined Higher Secondary Level). Clerks, lower-division clerks, postal assistants, and data-entry operators — same 20–50 KB photo, 10–20 KB signature.
- SSC MTS (Multi-Tasking Staff). Non-technical Group C posts. Mobile-heavy applicant base, which is exactly where Sukat’s phone-first workflow shines.
- SSC GD Constable. CAPF (BSF, CRPF, CISF, ITBP, SSB), NIA, SSF, and Assam Rifles. High-volume exam where portal rejections waste a window.
- SSC JE (Junior Engineer). Civil, Mechanical, Electrical, and Quantity Surveying engineers across central engineering departments.
- SSC CPO Sub-Inspector. Delhi Police and CAPF SI recruitment — identical OTR specification.
Tuned for SSC’s tight ceilings
UPSC gives you 300 KB of headroom. SSC gives you 50. The compressor needs to be precise, not generic.
Lands inside the SSC window first try
SSC’s 50 KB photo cap is below what most camera apps export at any quality setting. A blunt quality slider overshoots or undershoots. Sukat binary-searches for the highest quality that fits under 50 KB — the safe target is ~30 KB, leaving a margin against portal rounding. Same logic for the signature at ~15 KB under the 20 KB cap.
Faces stay recognisable at 30 KB
SSC’s 50 KB photo cap sounds aggressive, but a 300×400 px JPEG portrait holds face geometry cleanly down to 30 KB — eye, nose, and mouth edges are the highest-entropy parts of the image and the JPEG encoder weights them first. Sukat’s pipeline preserves those edges before trimming background detail.
Signature ink stays crisp at 15 KB
A signature is line-art on white — the most compressible content there is. A 600×200 px signature scan typically lands at 15 KB JPG with no visible edge softening. Sukat’s encoder prioritises stroke contrast over paper texture, so the ink stays sharp while whitespace compresses for free.
JPG output by default
SSC explicitly requires .jpg for both files — the portal rejects PNG, WebP, and HEIC outright. Sukat defaults the format dropdown to JPEG on this page so the right format is chosen even if you skim past it.
HEIC input handled
iPhone candidates can drop a raw .heic from the camera roll — Sukat decodes it in-browser and outputs JPG. No detour through Photos > Export.
Privacy
Photo and signature are sensitive identity assets. Sukat runs entirely on the Canvas API — nothing leaves your device. Verifiable in airplane mode after the page loads.
