Why forms reject photos and signatures
- The file is outside the KB range: too big is common, but too small (a plain signature on white paper) is rejected too.
- Wrong pixel size or shape: a phone photo is tall and huge, while forms want an exact small size.
- A grey or shadowy background behind the signature, or a signature that's tiny inside a big white area.
- The wrong format: forms want JPG/JPEG, not PNG or HEIC from an iPhone.
Each page above fixes all four: it crops to the right shape, makes signature paper pure white, saves a JPG at the exact pixel size and keeps the file inside the KB range, padding it safely if a file would be too small.
Frequently asked questions
Which exams and forms are covered?
IBPS, SBI, SSC, UPSC, JEE / CUET, NEET, RRB, PAN, Passport photo. The passport photo maker works for any form that asks for a 3.5 × 4.5 cm photo.
Are my photo and signature uploaded anywhere?
No. Everything happens inside your browser on your own phone or computer. Your files are never sent to a server.
What if the official notice says something different?
Notices change from year to year. Open “Change the limits” on any document and type the size from your notice: the tool follows it exactly.
The site says my file is too small, what do I do?
This tool never makes a file smaller than the minimum. If a picture is very plain (like a signature on white paper) it adds harmless padding inside the JPG so it meets the minimum size.
Can I use my phone?
Yes. Take a clear photo of your signature or thumb impression in good light, then add it here. The background clean-up makes the paper pure white.
