What is Ash Tools?

Ash Tools is a privacy-first collection of browser apps for media processing, document workflows, and coding utilities. It is built for people who want fast tools without sending files to external servers.

  • ✓ Everything runs on your device using WebAssembly/WebGPU
  • ✓ Sensitive files stay local and are never uploaded by default
  • ✓ Most tools continue to work even when you are offline

How does this help you?

For creators: Compress videos, optimize images, and package assets quickly.

For teams: Merge PDFs, zip project folders, and share cleaner outputs.

For developers: Benchmark snippets, generate regex, and run sandboxed code.

For privacy: Process local files directly in-browser with no upload step.
