What Tooler does
Tooler is a browser-based toolkit for everyday file processing and practical calculations. You can compress videos, convert images, extract audio, run OCR on screenshots, and convert documents without creating an account. The goal is direct utility: open a tool, upload a file, choose options, and download the result.
In addition to file tools, Tooler includes calculator and utility pages for finance, dates, health, unit conversion, writing tasks, and developer workflows. Each page is purpose-built with focused input fields and immediate output, so users spend less time navigating and more time finishing the task.
