SSC Signature Upload Errors — Solved
The exact rejection messages SSC aspirants see while uploading a signature or photo — and how this tool fixes each one.
“Signature size should be less than 20 KB”
✓ Fix: The tool auto-compresses your signature to land inside 10–20 KB — the size gauge turns green when it's accepted.
“Signature size should be greater than 10 KB”
✓ Fix: A plain signature often compresses below 10 KB; the tool automatically lifts it back into range without changing how it looks.
“Dimension of the image is not correct”
✓ Fix: Output is set to the exact 709×236 px (6.0×2.0 cm at 300 DPI) SSC expects for signatures, and 413×531 px for photos.
“Image must be in JPG/JPEG format”
✓ Fix: Whatever you upload (PNG, HEIC, etc.), the result is always saved as a proper JPEG.
“Signature is blurred / miniature”
✓ Fix: A live source-quality check warns you before processing and tells you exactly how to get a sharp scan that won't be rejected.
“Signature is not horizontally aligned”
✓ Fix: Use the rotate buttons to straighten a tilted scan so your signature sits perfectly level.
How to Resize for SSC
Four steps — and the checklist confirms it's upload-ready.
Pick a mode
Choose Photograph or Signature — each loads the correct SSC size automatically.
Upload your image
Drag in or choose a JPG/PNG; rotate if a scan is sideways or tilted.
Crop to frame it
Drag the aspect-locked box over your face or signature.
Generate & download
Get an exact-size JPEG inside the KB limit, then download it.
Frequently Asked Questions
Required sizes, why signatures get rejected, hitting 10–20 KB, 300 DPI, privacy and which exams it covers.
My signature won't upload on the SSC website — how do I fix it?
Nearly every SSC signature upload failure comes down to four things: the file is the wrong size (must be 10–20 KB), the wrong format (must be JPG/JPEG), the wrong dimensions (about 6.0×2.0 cm), or it's blurred/tilted. Upload your signature here in Signature mode, crop it level, and the tool outputs a JPEG at exactly 709×236 px, 300 DPI, automatically squeezed into 10–20 KB — which is everything the SSC form checks. Then re-upload that file.
How do I reduce my SSC signature size to 20 KB (or raise it above 10 KB)?
Just open it in Signature mode and process — you don't set the size manually. The tool tries many JPEG quality levels to land under 20 KB, and if your signature is so plain that it compresses below 10 KB, it automatically pads the file back above the 10 KB minimum without changing how it looks. The size gauge shows green when it's inside the allowed range.
What size should my SSC photo and signature be?
For most SSC applications the photograph must be a JPEG of 20 KB to 50 KB, about 3.5 cm × 4.5 cm, and the signature must be a JPEG of 10 KB to 20 KB, about 6.0 cm × 2.0 cm, both at roughly 300 DPI. This tool produces both at the exact pixel dimensions (413×531 for the photo, 709×236 for the signature) and automatically squeezes the file into the right KB window.
Why does SSC keep rejecting my signature?
The most common reasons are: the file is outside the 10–20 KB range, it's the wrong format (PNG instead of JPEG), it's blurred or too small (miniature), or it isn't horizontally aligned. This tool fixes the format, dimensions and KB size for you, and warns you if your cropped area is too small to be sharp — and the rotate buttons let you straighten a tilted scan so it sits horizontally.
How do I make my signature 10 KB to 20 KB?
Upload a clear scan or photo of your signature, switch to Signature mode, drag the crop box tightly around the signature (keep it level), and press Make SSC Signature. The tool resizes it to 709×236 px and tunes the JPEG quality until the file lands between 10 and 20 KB. The size gauge turns green when it's within range.
What does 300 DPI mean and does this tool set it?
DPI (dots per inch) describes how many pixels fit into each inch of print. SSC asks for about 300 DPI, which is why the photo comes out at 413×531 px (3.5×4.5 cm at 300 DPI) and the signature at 709×236 px. The tool also writes 300 DPI into the JPEG's header, so the file genuinely reports 300 DPI.
My signature is below the minimum size — what do I do?
A very plain signature on white can compress to under 10 KB. Use a larger, more detailed scan, crop a little more area around the strokes, or scan at higher resolution. The tool pushes JPEG quality to the maximum to help reach the minimum, and tells you if it still falls short.
Is my photo or signature uploaded to a server?
No. Everything — cropping, resizing, compression and setting the DPI — happens entirely in your browser. Your image never leaves your device, nothing is stored, and there's no sign-up. That keeps your documents private.
Can I use this for SSC CGL, CHSL, MTS, GD and other exams?
Yes. The photo and signature specifications (20–50 KB photo, 10–20 KB signature, JPEG, ~300 DPI) are the standard SSC One-Time-Registration requirements used across CGL, CHSL, MTS, Constable GD, Stenographer, JE and other SSC exams. Always cross-check the exact numbers in your specific notice, and adjust if it differs.
Does cropping reduce my photo's quality?
Cropping keeps the selected pixels at full quality; only the final resize and JPEG compression affect quality, and the tool uses high-quality resampling plus the highest JPEG quality that still fits the KB limit. Start with a sharp, well-lit source for the best result.
