Compress Image to Exact KB — Perfect for Document Portals
Many online application portals, especially government recruitment sites (UPSC, SSC, NEET, JEE, IBPS), have extremely strict requirements for image uploads. Instead of generic quality adjustments, they mandate that files fit within tight bounds (e.g. exactly under 20KB or 50KB). Our tool allows you to input your exact target size in kilobytes and performs the optimization automatically.
Why Exact Size Caps Exist
Official portals process millions of applications and operate on legacy storage systems. By forcing exact size limits, they keep their server databases lean and load times fast. Our tool targets the requested size cap, adjusting JPEG quality and chroma subsampling to find the perfect balance.
Local, Secure Image Compression
Identity cards, signatures, and thumb impressions are highly personal. To protect your data, our tool runs 100% in your browser. Your images are never sent to external servers, ensuring your private documents remain secure on your own machine.
