ToolMaster

Intro

ToolMaster is an all-in-one, browser-based utility suite that groups 70+ tools for PDF, image, developer, text, finance and design tasks. The site describes the tools as free to use and emphasizes privacy with phrases such as “100% private” and “zero uploads.” Tools run in the browser and are implemented to take advantage of WebAssembly for near-native speed, so processing happens locally rather than being sent to remote servers.

Key Features

• A broad collection of browser tools (70+), available without installs.
• PDF utilities including merge, split and compress.
• Image utilities such as compressor, resize and convert functions.
• Developer utilities like a JSON formatter and an API tester.
• Finance utility examples include a GST calculator.
• Privacy-first operation: the product states zero uploads and local, in-browser processing.
• Designed to run with WebAssembly for improved performance in modern browsers.

Who this is for

• Users who want quick, no-install utilities for common file and text tasks.
• Developers and designers that need lightweight formatters, API testing and image/PDF tools in the browser.
• Finance or office users who need simple calculators (for example, GST) alongside document tools.
• People who prefer tools that operate locally in the browser and aim to avoid cloud uploads or account signups.
