What does in-browser processing mean?
JavaScript loaded by the page performs the processing on your device and returns the result on screen or as a download. The browser can read only files that you explicitly select.
Each Develop Tools page explains how it handles input data. Features that require network access, such as clock checking, clearly state that exception on the page.
Please check before use
- Check if the URL of the page is HTTPS for a legitimate domain.
- Check "Privacy" and "Restrictions" at the bottom of the tool.
- Extract only the necessary parts of sensitive data before entering them.
- Visually check the processing results before saving or sharing them.
Differences with browser save
Processing in the browser is different from storing data in the browser. Some tools use localStorage to retain display settings, but this does not mean that the entered code or selected files are stored. In private browsing mode, saved settings may be removed when the session ends.
