About our free pdf & file tools

Browser-based file helpers for converting images to PDF, estimating sizes and prepping documents. Whether you are a small business owner, a tradesperson on the job site, a restaurant manager pricing a menu, or a homeowner planning a project, our pdf & file tools are designed to give you a clear answer fast — with no signup, no paywall, and no data leaving your device.

Every tool in the PDF & File Tools category was built around a real-world question we kept seeing online: "How much paint do I need?", "What should my menu price be?", "How do I make a clean invoice?". Instead of forcing you through a long form or a marketing funnel, we give you the calculator or generator at the top of the page and the helpful background information below.

Designed for the US market

Our pdf & file tools use US units (feet, square feet, inches, gallons, cubic yards, ounces) and US dollars by default, with formulas tuned for typical American homes, contractors, small businesses and restaurants. If you are in Ohio, the Midwest, or anywhere in the United States, the defaults will feel familiar.

Browser-based and private

Every calculation happens locally in your browser using JavaScript. Image and file tools use the HTML canvas API, so your photos and documents never leave your device. That makes the tools fast, private and usable even on slow Wi-Fi.

Always free

All 4 pdf & file tools on this page will remain free forever. The site is supported by non-intrusive advertising, not by selling your data or hiding the tool behind a paywall.
