Image Resizer PC20 KB is tiny — here's what it's really for
20 KB is a very small file, and it's almost always a signature or a small exam-photo limit — not a full-size portrait. For a black-ink signature on white paper it's plenty; for a colour face photo it's demanding, and some softening is normal and unavoidable at this size. That's just how compression works, and we'd rather tell you straight.
Whatever you load, the app fits the best quality it can under 20 KB and shows the result in the preview, so there are no surprises when you upload.
- SSC: signature 10–20 KB (the photo itself is larger, 20–50 KB).
- IBPS: signature 10–20 KB (140×60 px), JPG.
- GATE: signature 4–30 KB — 20 KB sits comfortably inside.
- For any other field, check your portal's exact requirement.
Keeping a signature clean at 20 KB
Signatures compress beautifully because they're mostly white with thin dark lines. To get a crisp 20 KB signature, crop tightly around the writing and match the pixel size the form asks for.
- Crop close so there's no empty border eating into the file size.
- Use JPG and the exam's pixel size (often 140×60).
- Sign on plain white paper in dark ink for the cleanest scan.
- Avoid shadows — an even, bright photo compresses smaller and clearer.
If you need a photo at 20 KB, be realistic
When a form truly caps a photo at 20 KB, expect it to look softer than at 50 or 100 KB — there simply isn't room for fine detail. You can make the best of it by cropping tight to the head and shoulders, so the pixels that remain are spent on your face rather than the background.
If your portal actually allows more (many allow 50 KB for photos), use the higher limit instead — a 50 KB photo looks noticeably better. Only squeeze down to 20 KB when the form really demands it.
