Frequently Asked Questions (FAQ)

1. How to compress signatures under 20KB for UPSC, SSC, or IBPS forms?
Upload your signature photo and click the 'Under 20KB' card. The tool will repeatedly calibrate image quality so the final file strictly settles between 12KB and 19.5KB, ensuring portal acceptance without rejection errors.
2. Will compressing to 50KB make my passport photo blurry?
No. Our optimization engine eliminates metadata, thumbnail payloads, and redundant color space headers before adjusting lossy compression, preserving crucial facial details and clarity.
3. Are my private documents uploaded to third-party servers?
Never. This tool operates 100% locally in your device's browser memory using client-side JavaScript. Your photos are never transmitted over the internet or saved to remote databases.
