Free Browser Utilities

What is Free Browser Utilities?

This site hosts ten single-page utilities designed for developers, marketers, and creators. Every tool runs entirely within your web browser using client-side JavaScript. Files and data are processed locally on your device and never uploaded to any external server.

The collection includes format converters like SVG to PNG or WebP, data exporters such as JSON to CSV, and document handlers for splitting or merging PDFs. It also provides debugging and formatting aids including a regex visualizer, SQL formatter, and markdown previewer. Additional features cover social media image resizing, subtitle text cleaning, UTM link building, and WCAG accessibility contrast checking.

All applications require JavaScript and work across any modern web browser. The project is built with HTML5 and Tailwind CSS, and usage is completely free.
