Encoding and Data Conversion FAQ
Do these tools run locally?
Most RustPoint tools process input in the browser. Tools that need network access, such as DNS or WebSocket checks, only make requests after the user starts the check.
Does RustPoint store my input?
The local tools are designed to avoid server-side storage. Account favorites store only tool IDs for signed-in users.
How should I choose a tool in this category?
Start from the task you need to finish, then compare the short descriptions and tags. The catalog search can narrow tools by name, tag, and category.
