Client-Side Architecture

How OmniTools Works

Your data never leaves your computer. We process files, code, and math directly inside your browser.

Local Processing

100% In-Browser Execution

Traditional online converter sites require uploading files to a remote server. This poses privacy risks and relies on network speeds. OmniTools works differently:

  • FileReader API: We load image and text bytes straight into local memory.
  • HTML5 Canvas: Images are cropped, resized, and compressed on your GPU.
  • Web Crypto: Hashing algorithms are executed locally on your CPU threads.
  • Zero Logs: Since there is no server upload, your documents remain private.
🔒

100% Secure & Private

Your private details, receipts, photos, and files are safe from intercept.

Performance

Dynamic Library Loading

To keep the website incredibly fast, we do not load heavy scripts up front. When you click a tool, we download required libraries dynamically:

  • ✦ Scripts load from secure, cached public CDN networks.
  • ✦ Loaded modules are cached in RAM for subsequent launches.
  • ✦ Reduces initial landing page weight from 5MB to just 45KB!
  • ✦ Fully offline capable once tools have been run once.
