Resize Image to 20 KB Online: Government Form Signature Compressor
The universal target for government exam signatures. Compresses files strictly under 20 KB (20,480 bytes) with crystal-clear ink lines and zero server uploads.
The Standard Signature Limit for Indian Online Applications
Almost all major competitive examinations in India — including SSC CGL/CHSL/MTS, IBPS PO/Clerk, SBI, Railway RRB, and State PSCs — establish a strict maximum ceiling of 20 KB for candidate signatures. Uploading a 21 KB file triggers an immediate validation failure on the submission portal.
With ApplyReady, your file is processed directly inside your web browser. You can rotate, crop out margins, set custom dimensions, and download a guaranteed sub-20 KB image without compromising the clarity of your handwritten signature.

How to Prepare Your Signature for 20 KB Portals
- Use Crisp Black or Dark Blue Ink: A dark ballpoint or gel pen on clean, bright white unlined paper ensures the best contrast.
- Good Lighting, No Shadows: Take the photo from directly above in natural daylight to prevent gloomy shadows that inflate JPEG file size.
- Crop Away Blank Margins: The tighter you crop around the signature, the higher the resolution and clarity you can retain within 20 KB.
Frequently Asked Questions: 20 KB Signature Sizing
Common questions regarding the 20 KB limit.
What happens if my file is 20.2 KB?
Government exam portals measure file size strictly in bytes. 20 KB equals 20,480 bytes. If your file is 20.2 KB (20,684 bytes), the portal validator rejects the file. ApplyReady tests byte size iteratively to guarantee the output is strictly below 20,480 bytes.
Can I resize photos as well as signatures to 20 KB?
Yes. Any image, including ID photos and stamps, can be cropped and compressed to under 20 KB using this page.
