About the Image Upload Validator
The Image Upload Validator evaluates your prepared photograph and signature files against standard dimensions, aspect ratios, file size boundaries, and file formats before you upload them to official portals.
By auditing your files locally, you prevent common application rejections. Most portals use automatic filters that reject files immediately if they violate thresholds by even 1 pixel or 1 kilobyte.

Frequently Asked Questions
What checks does the validator run?
It checks the exact file size (in bytes), image height and width (in pixels), format extension, and calculates the aspect ratio bounds.
My photo passed the validation, will it be accepted?
Passing checks means the file structure matches specifications. You must still verify visual rules (e.g., white background, no sunglasses, visible ears).
