Why compress an image to exactly 20KB?
Twenty kilobytes is one of the strictest limits in online applications. It is the top of the range most Indian banking and SSC forms set for your signature (10–20 KB), and some portals cap even photographs at 20 KB. A normal phone photo is 150 to 400 times larger than that, so a percentage-based shrink almost never lands in range — this page works backwards from 20 KB and finds the quality, and if needed the dimensions, that fit.
Because a 20 KB budget is small, what you start with matters. Signatures compress beautifully — they are mostly white space — and usually stay crisp. Photographs keep enough detail for the tiny size at which forms display them, especially if you start from the camera original and crop tightly around the face before compressing.
Who needs a 20KB image?
- IBPS & SSC signatures — specified at 10–20 KB and 140 × 60 pixels
- Photographs on portals that cap uploads at 20 KB
- The lower, safest end of the SSC / IBPS photo range (20–50 KB) when a portal reads the rule strictly
- Small profile and ID photos for exam and job portals with tight upload limits

Frequently asked questions
Can I compress a signature to 20KB?
Yes. Signatures are mostly plain white background, so they reach 20 KB easily while staying sharp. Remember that IBPS and SSC also specify signature dimensions of 140 × 60 pixels — if your form checks pixels as well as kilobytes, our Signature Resizer sets both together.
Will my photo look blurry at 20KB?
At the size forms actually display your photo (about 200 × 230 pixels), a well-compressed 20 KB photo normally looks clear. Blurriness usually comes from re-compressing an already small copy — always start from the original camera photo, and crop before you compress.
My photo is under 20KB but still got rejected — why?
Size is only one rule. The form may also require JPG format (this tool always outputs JPG) or exact pixel dimensions. Read the form's photo instructions, and if dimensions are listed, use the Photo & Signature Resizer, which sets size and pixels together.
