Common mistakes to avoid
- Uploading PNG or a renamed HEIC — CBSE checks the real file format, not the extension
- A signature scanned vertically or cropped so tightly the ends are cut off
- A dark or cluttered background instead of plain white or light
Pro tips
- CTET states sizes in centimetres — 3.5×4.5 cm is 350×450 px, which this tool sets for you
- Keep the signature crop tight but leave a small white margin on all sides
- Aim for the middle of each range so a portal re-check never rejects the file
