Frequently Asked Questions About ExactCompress
How does ExactCompress compress images to exact target KB without uploading? ▼
ExactCompress uses an 8-step binary search algorithm executed locally via the HTML5 Canvas API in your browser. It calculates the exact JPEG compression quality needed to hit your target byte limit without sending any data over the internet.
Can I add candidate Name and Date of Photo for SSC and UPSC exams? ▼
Yes! Toggle the "Name & Date on Photo" switch, type your name, and click "Use Today's Date" or enter your photo capture date. The tool renders a compliant bottom band across the photo before compressing to under 50 KB.
How does the Signature Ink Enhancer work? ▼
Our signature enhancer analyzes pixel luminance. It turns off-white paper, shadows, and scanner noise into crisp pure white (#FFFFFF) while intensifying dark black or blue ink strokes, ensuring acceptance on 10KB–20KB portals.
Can I convert JPG images directly into a PDF under 100 KB? ▼
Yes. Switch the export format to "Document (.pdf)". ExactCompress creates a valid single-page PDF 1.4 byte stream wrapping your image without needing bulky external libraries or server uploads.
Are my personal documents and biometric photos safe? ▼
100% safe. Files never leave your computer or mobile device. All processing happens offline inside your browser memory and is immediately wiped when you close or refresh the page.
