Frequently Asked Questions
Why are signature photos rejected in online recruitment forms?
Photos clicked directly from smartphones often capture shadows, yellowish indoor light, or ruled notebook lines. Automated scanners classify this as poor contrast, leading to application rejection. This tool clears all shadows to render a pure white background.
Can this tool clean Left Thumb Impressions (LTI)?
Yes! Blue or black ink thumb impressions on paper can be cleaned with the same settings. Select "Blue Ink" or "Original Ink Tone" to retain ridge details while removing paper shadows.
