Resize signature to 10KB–20KB for SSC (CGL, CHSL, GD, MTS)
SSC portals accept signatures only in JPG/JPEG between 10KB and 20KB, scanned at roughly 4.0cm × 2.0cm — about 236 × 79 pixels. Sign with a black ink pen on plain white paper, photograph or scan it, and this tool crops to the exact aspect ratio, flattens the background to pure white, and compresses into the 10–20KB window. Files under 10KB get rejected as over-compressed; over 20KB the portal refuses the upload — the KB-range targeting handles both edges automatically.
UPSC signature size: 20KB–100KB at 350×350 pixels
UPSC CSE requires the signature image between 20KB and 100KB with dimensions in the 350–500 pixel range, black ink on white paper. From the 2026 cycle UPSC asks candidates to sign three times one below the other and scan all three as a single image — prepare that sheet first, then upload it here and select the UPSC preset. Always cross-check the exact figures in your cycle's official notification PDF before submitting.
NEET signature upload: 4KB–30KB in JPG
NTA accepts the NEET UG signature between 4KB and 30KB in JPG format, full signature in running letters with a black ballpoint pen. The NEET preset targets this range while keeping stroke edges sharp — the grayscale and contrast boost makes thin pen lines survive heavy compression instead of dissolving into the white background.
How the KB targeting works
The tool binary-searches JPEG quality until the output lands inside your target KB range, after resizing to the exact pixel dimensions your exam demands. Everything runs in your browser via the Canvas API — your signature never leaves your device, which matters for a document that authenticates your identity on a government portal.
Frequently asked questions
What is the correct signature size for SSC CGL 2026?
10KB to 20KB in JPG/JPEG format, approximately 4.0cm wide × 2.0cm high (about 236 × 79 pixels). Sign with black ink on white paper. Blurred or miniature signatures are rejected.
What is the UPSC signature size limit?
20KB to 100KB, with image dimensions in the 350–500 pixel range. UPSC 2026 onwards requires three signatures signed one below the other, scanned as a single image. Verify against your notification PDF.
What signature size does NEET accept?
4KB to 30KB in JPG format. Sign in full running letters with a black ballpoint pen on white paper — initials or capital-letter signatures can be treated as invalid.
Why does the portal keep rejecting my signature file?
Almost always wrong KB range, wrong aspect ratio, or a non-JPG format (PNG/PDF/HEIC). This tool fixes all three in one pass: exact pixels, JPG output, and compression targeted inside the required KB window.
Is my signature uploaded to a server?
No. All cropping, resizing, and compression happen entirely in your browser. The file never leaves your device.
