Exam Photo & Signature Compressor

Applying for government jobs in India—including boards like **SSC (Staff Selection Commission)**, **UPSC (Union Public Service Commission)**, **IBPS (Banking)**, and state-level exams—requires filling out long registration forms. A very common issue candidates face is when their scanned passport photograph or signature fails to upload because the file size exceeds the strict limits (standardly **20kb to 50kb** for photos, and **10kb to 20kb** for signatures).

1. How Client-Side Browser Compression Works

When you use standard online compressors, your private passport photo is sent to a server over the internet. This poses security and privacy risks. Our tool uses **HTML5 Canvas technology** to process images entirely inside your browser.

When you select a file:

1. The browser reads the image file locally without uploading it to any external server.
2. The image is drawn on a virtual canvas, scaling its overall pixel boundaries to a web-friendly size (standardly keeping aspect ratios intact).
3. The tool runs a fast loop that adjusts the compression quality factor (between 0.1 and 1.0) and generates temporary JPEGs until the estimated file size matches your requested target limit (e.g. 20kb or 50kb).
4. Since the operations are completed client-side, the process is instantaneous and keeps your private data secure on your own device.

3. Crucial Rules to Avoid Application Rejections

An incorrect file size is not the only reason photographs get rejected. The automated image scanners used by portals check for several visual standards:

• Face Coverage: Your face must occupy at least 70% to 80% of the photograph area. The camera must look straight at your face. Avoid side profiles.
• Background Contrast: Portals prefer a clean, light-colored background—white or light blue are standard. Avoid dark or textured backgrounds.
• Spectacles & Eyewear: In recent years, SSC has rejected photos showing candidates wearing spectacles due to flash reflections. Take off your glasses before taking the photo. Caps, hats, and headphones are strictly forbidden.
• Recent Capture: The photograph must be captured recently, standardly not older than 3 months from the notification date. Some portals (like UPSC) require you to write the date of capture on the lower half of the photo.
• Signature ink rules: Always sign on a clean white paper using a **black ink pen**. Blue ink signatures are sometimes flagged as low contrast by scanned readers.
