Tentaco is a collection of 100+ free online tools that run in your browser. No sign-up, no upload — most tools process your data locally on your device.
Studios
Studios are immersive workspaces that bundle related tools into one page. Switch modes from the sidebar without losing context. Tentaco currently ships 18 live studios: PDF, Image, Video, HTML, Code, Text, Audio, Data, Design, Web & SEO, Security, Calculator, Finance, API, Converter, Letter and Document.
Keyboard shortcuts
Press ⌘K (Mac) or Ctrl+K (Windows/Linux) anywhere on the site to open the command palette. Search tools, studios and pages instantly — then press Enter to jump there.
Privacy & local processing
The vast majority of tools — including every studio — run entirely in your browser. Your files and pasted text are not uploaded to our servers unless you explicitly use optional file-sharing features.
