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.
| Exam / Commission | Passport Photo Limits | Signature Limits | Special Requirements |
|---|---|---|---|
| SSC CGL (2026) | Live photo capture in the SSC application flow | 10 KB – 20 KB (about 472 × 236 px) | JPEG/JPG; about 4 cm × 2 cm at 300 DPI. Check the current SSC CGL notice. |
| UPSC (IAS, IPS, NDA, CDS) | 20 KB – 300 KB (Min 350 × 350 px) | 20 KB – 300 KB (Min 350 × 350 px) | Square format; name & date recommended |

Key compliance rules enforced by automated server validators across major recruitment portals:
| Compliance Factor | Strict Portal Rule | Common Error / Rejection Cause | Instant Pre-Upload Fix |
|---|---|---|---|
| Signature Casing | Running Handwriting Only | Signatures in ALL CAPITAL LETTERS are automatically disqualified. | Sign in natural cursive script using black ballpoint ink on crisp white paper. |
| File Size Ceiling | Strict Upper Boundary (e.g. 50.0 KB) | A 50.4 KB image triggers an immediate server upload rejection error. | Use our binary search canvas compression to lock between 20 KB and 45 KB. |
| Date Stamp (DOP) | Candidate Name & Capture Date | Rejection by state PSCs if photograph is undated or older than 3 months. | Enable our 1-click Date on Photo (DOP) stamp overlay before downloading. |
| Spectacles & Headgear | Clear Eyes & Neutral Expression | Glare on glasses or caps concealing hairline causes AI facial mismatch. | Remove reading spectacles, sunglasses, and caps; ensure white backdrop. |
Unlike other online converters that upload your personal passport photos and signatures to external servers, UseCOS processes everything directly inside your browser memory using HTML5 Canvas. Your image files never leave your computer or phone.
