Compress Image to 15KB
To reach a 15 KB target, the tool steps JPG quality down until the file crosses just under 15 KB, then hands you the result. This size is the classic Indian government exam requirement, where signature uploads are often specified as 10 to 20 KB. It gives you a little more room than a 10 KB cap, so quality holds up better on small images.

The standard exam form size
If you have filled out an online exam application in India, 15 KB will look familiar. Boards and recruitment portals routinely publish signature limits of 10 to 20 KB and photo limits a step higher, and 15 KB sits right in that signature window.
The extra 5 KB over a 10 KB cap matters more than it sounds. It lets you keep slightly larger pixel dimensions or a cleaner scan, which is the difference between a signature that reads clearly and one that looks broken up.
Getting a clean result
Scan or photograph the signature on plain white paper with good, even light. High contrast between ink and background compresses more efficiently, so more of your 15 KB budget goes toward sharp edges instead of gray noise.
If the form has separate photo and signature fields, compress each to its own required size rather than reusing one file. All processing happens on your device, so nothing you upload to the exam portal passes through our servers first.

Frequently asked questions
Is 15 KB the right size for Indian exam signatures?
Very often, yes. Many exam portals specify a signature between 10 and 20 KB, and 15 KB lands safely inside that range. Confirm the exact numbers on your specific form.
Can I use 15 KB for the photo field too?
Check the form. Photo fields usually allow a larger size, such as 20 to 50 KB, so you may not need to squeeze the photo as hard as the signature.
My file is 15.2 KB, will it be rejected?
Possibly, if the limit is a hard maximum. The tool aims just under your target, but if you are borderline, reduce the dimensions slightly and recompress for a safe margin.
