Accurate Photo Size Reducer for Online Form Uploads
When applying for government jobs (SSC, UPSC, RRB), bank exams (IBPS, SBI), or state-level university admissions, the portal systems are notoriously strict about file sizes. If a form requires a signature under 20KB, uploading a file that is even 20.01KB will result in an immediate rejection error.
Our Exact KB Image Compressor is specifically engineered to solve this problem. Instead of blindly lowering quality and hoping it fits, our script uses a mathematical "Binary Search Algorithm". It tests your image in real-time multiple times, adjusting the compression curve until the file size lands perfectly just below your target limit (e.g., exactly 49.8 KB for a 50KB limit).
100% Client-Side Safe & Secure Processing
Your identity photos, signatures, and confidential documents like Aadhar or PAN cards should never be uploaded to random servers. This tool processes the compression entirely using your device's browser memory (HTML5 Canvas). Your files are never uploaded to the internet, guaranteeing complete data privacy.
Common Required Image Sizes
- 20 KB Limit: Standard limit for scanned Signatures (SSC, IBPS, Parivahan).
- 50 KB Limit: Standard limit for Passport Size Photographs.
- 100 KB Limit: Used for ID proofs (Aadhar, PAN, Thumb Impressions).
- Custom Limit: Some portals may ask for 30KB or 300KB. Use the Custom option to generate an exact size.
How The Smart Algorithm Works
Quality Tuning
The engine iterates through JPEG quality levels (1% to 100%) to find the highest possible quality that strictly obeys the file size rule.
Dynamic Scaling
If an image is too large (like a 5MB phone photo), lowering quality isn't enough. The tool automatically rescales the dimensions intelligently to hit the target.
