Target size is pre-set to 20KB. The algorithm adjusts quality automatically.
Our engine runs multiple iterations in milliseconds to find the maximum possible quality under 20KB.
Get your verified sub-20KB image ready for immediate portal submission.
When government and banking portals were built two decades ago, server storage was expensive. Today, many legacy systems still enforce rigid 20KB file size caps. Modern smartphones take pictures that are 5,000KB (5MB) or more—250 times larger than the allowed limit! Our tool bridge this gap by calculating the exact quantization matrices required to deliver a compliant file.
Unlike other online image converters that transfer your confidential documents, family pictures, and signatures to remote cloud servers, this toolkit runs WebAssembly and HTML5 Canvas algorithms entirely inside your browser sandbox. Your files never leave your device.
