Note for Local Files

To use CodePrettify with local files (e.g., file:///C:/code/data.json), you must enable "Allow access to file URLs" in your browser's extension management page, such as chrome://extensions or edge://extensions.

Privacy & Access

Why The Extension Needs Page Access

CodePrettify reads supported raw-code pages in the current tab so it can format, validate, compare, search, and export the file you are already viewing. That handling stays local in your browser and is limited to the user-facing features described on this site, in the product UI, and in the browser extension marketplace listings.

What it uses

Supported page content, the resource URL, browser-reported content type, character encoding, response-size hints, timing hints, and local settings.

What it does not do

It does not send your file contents to FixQuotes, sell browsing data, inject ads, or read request headers, response headers, cookies, or request bodies.

Rare network retry

If a JavaScript file looks incorrectly decoded with a legacy charset, CodePrettify may re-request the same URL directly from the site you are on to recover valid UTF-8 text.

Full details are in the privacy policy.
