About Cortex Digital Hub
Free online tools, built so that your files stay on your device.
What we do
Cortex Digital Hub is a collection of free online tools for real estate visuals, images, PDFs and video. Each tool runs as code inside your web browser. When you compress a photo or convert a floor plan here, the work happens on your phone or computer, and the file is never uploaded to us or to anyone else.
Why we built it
The project began in Hyderabad with a real estate marketing problem: buyers find flat 2D floor plans hard to read, and the existing "2D to 3D" services produced attractive pictures that did not match the plan. We built a converter that keeps the geometry exact, then kept going with the everyday tools people search for most: image compression and conversion, PDF conversion, video compression.
How we keep it free
Because the tools run in your browser, we have no servers to pay for processing or storage. The site is supported by advertising, placed outside the tool area and never inside your workflow. Some advanced features that depend on paid AI models may be offered as optional paid extras in future; the core tools stay free.
