Get your signature ready for an exam or government form
Online exam and government portals (SSC, IBPS, SBI, UPSC, state PSCs and more) want your signature as a JPEG at a precise pixel size and under a tight KB limit — often around 140×60 px and under 20 KB — on a clean white background. A phone photo of your signature is far too big and has a grey, shadowy background. This tool whitens the paper and shadows so only the ink remains, trims the empty margins, and resizes it to the exact target — all in your browser.
Who uses this tool
Applicants filling exam forms for SSC, IBPS, SBI, UPSC, RRB and state PSCs, where the signature must be a clean JPEG within an exact KB and pixel limit, and anyone who only has a phone photo of their signature on paper.
How to use it
- Sign on plain white paper, take a clear photo (or scan it), and choose that image.
- Pick your form's preset (or type the exact pixel size and KB limit). Adjust the cleaning strength if the background isn't fully white.
- Download the cleaned JPG — it's already at the right size and within the limit.
Frequently asked questions
What size should my signature be?
Usually a JPEG around 140×60 px and under 10–20 KB. Confirm the exact range in your exam's notification.
How do I clean a photo of my signature?
Photograph it on white paper and upload — the tool whitens the paper and shadows so only the ink remains, trims the margins, and resizes to your target.
Does it change my signature?
No — it only cleans the background, trims empty space and resizes. Turn off cleaning or auto-crop any time.
Is it private?
Yes — the image is processed in your browser and never uploaded.
