Documentation
Use the tools without guessing.
Simply Tools keeps the main workflow on each tool page. This documentation explains the shared rules: what runs locally, which files are supported, and how to handle sensitive data safely.

Core usage model
Open a tool, complete the task, then download or copy the result. Long explanations stay below the workspace so the first screen remains useful.
- PDF and image tools process selected files in the browser.
- Text and developer tools operate on pasted input inside the current session.
- Every tool page includes usage steps, privacy context, and related tools.
Tool guides
Each tool page includes quick steps, common questions, privacy notes, and related utilities.
File handling
Document and image tools work with files selected in the browser. Keep the tab open until the final download completes.
Sensitive data
Local processing helps, but device security still matters. Avoid public screenshots, shared machines, and unsafe browser extensions.
