Image Resizer PCWhat a 10 KB image is actually for
10 KB is tiny — about the size of a short email. At that size a full-colour face photo starts to look blocky, so most people who need 10 KB are really uploading a signature, not a photo. Several Indian exam portals cap the signature between 10 and 20 KB, and 10 KB sits right at the bottom of that range.
If a form seems to want a 10 KB photo rather than a signature, read the instructions again — many portals that look like they want 10 KB actually allow 20–50 KB for the photo and reserve 10–20 KB for the signature.
- SSC (CGL/CHSL/MTS/GD): signature 10–20 KB, JPG
- IBPS (PO/Clerk/RRB/SO): signature 10–20 KB, around 140×60 px, JPG
- Always confirm your own portal's exact figure before uploading
How to keep a signature sharp at 10 KB
The trick at 10 KB is to start small and clean. Sign in dark ink on plain white paper, scan or photograph it in good light, then crop tightly so there's no wasted background — every pixel you remove is weight you don't have to spend.
Save as JPG. For line art like a signature you can try PNG too, but JPG almost always squeezes smaller at this size. Some loss of crispness is unavoidable when you push a file down to 10 KB — that's just physics — but a tightly cropped black-on-white signature stays perfectly legible.
- Crop out white margins before resizing
- Keep pixel dimensions small (roughly 140×60 px for a signature box)
- Use JPG and check the preview weight before you save
Resize to 10 KB without uploading anything
Your signature is sensitive — it's literally your handwriting. The popular 'resize to 10 KB' websites make you hand that file to a server you don't control. Image Resizer PC runs entirely on your own Windows machine, so nothing is uploaded, no account is needed, and there's no watermark on the result.
You type 10 KB once and the app does a quick search over quality settings — downscaling the pixels if it has to — to land at or just under 10 KB automatically. No trial-and-error sliders.
