About Size to KB

Size to KB (SizeToKB) is the official free website at sizetokb.in (also sizetokb.com). We help students and job aspirants across India prepare photographs, signatures, thumb impressions and handwritten declarations so they match the exact kilobyte (KB) and dimension rules on online application portals.

If you searched “size to kb”, “sizetokb” or “sizetokb.in”, this is the site. Compress exam photos and signatures privately in your browser — no signup, and we do not keep your files on a server.

Who this is for

Size to KB is built for people filling SSC, UPSC, Railway (RRB), IBPS, SBI, India Post GDS, state PSC / police and similar forms. The painful moment is almost always the same: the portal rejects a phone photo that is 2 MB, or a signature that is 45 KB when the notice asked for 10–20 KB. We exist to fix that step without installing an app.

How Size to KB works

1. You open a tool (exam preset, Reduce KB, signature cleaner, PDF utility).
2. You upload or take a photo — processing runs on your phone or laptop.
3. You crop, hit the KB target, then Free Download the JPG/PDF.
4. You upload that file to the official form. We never see the file after you leave.

Details are in our Privacy Policy. Browser-side processing is the product principle, not a marketing line.

What you can do here

• Exam presets for 190+ recruitments (photo, sign, thumb, declaration where needed)
• Custom min–max KB resize with optional cm / px dimensions
• Signature cleaner aimed at the common 10–20 KB bank / SSC band
• PDF to JPG, unlock PDF, marksheet / certificate size helpers
• Step-by-step form upload guides that explain rejections, not only the button

What we are not

We are not affiliated with SSC, UPSC, RRB, IBPS, India Post or any exam board. KB limits change; always re-check the latest official notification PDF before you submit. See our Disclaimer.
