Small, practical browser tools with clear inputs, outputs, and limitations.

CZF Tools is built around a straightforward idea: each tool should solve one focused job quickly, work well on desktop and mobile, and keep the main action easy to find.

Most tools run directly in the browser. That keeps everyday tasks fast and avoids unnecessary uploads for common formatting, conversion, and text cleanup workflows.

CZF Tools is an independent project created and maintained by a solo developer. It grew from repeatedly needing small utilities while debugging web applications, preparing content, and moving data between different formats.

New tools are added when they solve a distinct task, not simply to create another page. Existing tools are reviewed for browser compatibility, understandable error states, and useful output before release.

Automated tests cover shared conversion and formatting logic, while interactive tools are also checked in a real browser. If a result looks incorrect, visitors can report the page URL, browser, example input, and expected output through the contact page.

CZF Tools is intended for everyday productivity. Security-sensitive, legal, financial, or production decisions should always be verified against the relevant official documentation or a qualified expert.
