Who Needs Images Under 30KB?

A 30KB limit is the standard for government exam signature uploads across SSC, IBPS, UPSC, and railway recruitment portals in India. Signature images must be small, clean, and within strict byte limits for form submission to succeed.

Portal / Form	Size requirement
SSC CGL / CHSL / MTS	Signature: 10–30KB, 140×60px JPEG
UPSC Civil Services	Signature: 20–30KB, 140×60px
IBPS PO / Clerk / SO	Signature: 10–30KB, 140×60px
RRB (Railway Recruitment)	Signature: 10–30KB
NEET UG (NTA portal)	Signature: 10–30KB
State PSC portals	Signature: typically 10–30KB

For signature scans: use a white background, sign with a black or dark pen, crop tightly to the signature boundaries, and resize to 140×60px. A clean signature image at these dimensions typically lands at 5–15KB — well under 30KB.

Frequently Asked Questions

: The output is guaranteed to be at or below 30KB. The exact size depends on image content — you may get 38KB for a 50KB target, or 96KB for a 100KB target. Any file under the limit will pass portal validation.
: Yes. This tool is designed specifically for government exam portals, visa applications, and job sites that set strict KB limits. The output is a standard JPEG file — the format accepted by all major portals.
: Yes. Upload HEIC files directly — they are automatically converted to JPEG before resizing. No separate conversion step needed.
: If the image cannot be reduced below 30KB even at minimum quality (very rare, typically only for very small targets under 10KB), the tool shows a warning and outputs the smallest possible file. For very small targets, try cropping the image first.
