Signature Guidelines
- •Sign on plain white paper using black or dark blue ink
- •Scan or photograph the signature in good lighting
- •Crop tightly so there are no large blank borders
- •No digital / typed signatures — must be a real handwritten one
Everything runs in your browser — your photo never leaves your device. Always verify specs against the latest official notification before final submission.
Before you upload to IISc / IITs (GATE Committee)
- Use a recent signature and save the final file as JPG.
- Confirm the image is exactly 400 x 120 pixels before submitting.
- Keep the file between 3 KB and 1000 KB to avoid portal upload errors.
- Use a plain white background with no patterns, shadows or extra border.
Common rejection checks
Most GATE upload failures come from the same small issues: wrong pixel size, wrong file type, a file just above the KB limit, or a crop that leaves too much blank space. This page targets the 400 x 120 px and 3-1000 KB specification so you can download a ready-to-upload file and still inspect it before final submission.
If your source image is from an iPhone, convert HEIC to JPG first. If the background is not clean enough, use the background remover before running the final resize.
