Pro-Tips for Successful Online Form Submission:

White Background: Ensure passport photo has a clean white or plain light background.
Black Pen Signature: Sign on plain white paper using a black gel/ballpoint pen for high digital clarity.
Aspect Ratio Lock: When resizing photos, uncheck "Lock Aspect Ratio" if the form enforces exact width x height pixels (e.g. 200x230 px).
100% Client-Side Security: RawByte Tools processes your photos locally in your browser so your Aadhaar, PAN, and certificate PDFs are never uploaded to remote servers.
