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.

Quality and privacy standards
Tooler is designed for practical, task-focused workflows. We prioritize speed, clear tool interfaces, and predictable output. Files are processed server-side and are deleted automatically after one hour. Tool pages include usage guidance and FAQs to reduce failed conversions and improve first-try success rates.
If you need business-critical handling or legal retention guarantees, use dedicated enterprise infrastructure. Tooler is built for fast self-service utility work, drafts, and daily file operations.
How to choose the right tool
Pick tools by output requirement, not by habit. For images, use PNG when you need transparency, JPG when file size matters for photos, and WebP for modern web delivery. For video, start with H.264 and moderate compression, then tune only if the output is still too large. For OCR, use high-contrast source images with straight alignment to improve extraction accuracy.
For calculators, treat outputs as practical estimates unless the page explicitly states a legal or standards-based formula. Financial and compliance workflows should always be cross-checked against official policies, lender terms, or tax guidance.
