AG Tools is a free online collection of calculators and browser-based tools for finance, PDFs and images, health, creators, and everyday tasks. Choose a category below to open a tool, enter your information, and review the result. Individual tool pages explain their inputs and important limits.

Learn how to calculate net worth, organize assets and liabilities, understand positive or negative net worth, and track your financial progress over time.
We aim to show the inputs, assumptions, and limits that matter, so a result is easier to judge.
Labels, units, rounding, and important assumptions should be visible where you need them.
Tools should process information on your device when that is practical and explain when it is not.
Estimates stay estimates, and high-stakes decisions deserve professional or authoritative confirmation.
Read our approach →Start with the AG Tools directory and choose the appropriate tool collection: File & PDF Tools, Financial Tools, Health Tools, Creator Tools or Everyday Tools. The public browser-based tools are designed to work without a mandatory account. Each individual page explains what the tool does and any device, file-format or calculation limits before you use it.
Our browser-first tools are designed to process information locally when practical, particularly file operations and calculations that do not need an external service. Some capabilities, such as fetching public information from a third-party source, may require a network request. Always read the privacy and processing explanation on the particular tool; do not assume every online service has identical data handling.
Open the individual tool page and check its inputs, output format, assumptions and supported file types. For financial or health estimates, compare the documented method and limits rather than treating one number as a guaranteed outcome. For files, choose the workflow that matches the source format, desired export format and device capabilities.
The collections aim to work across modern browsers and screen sizes, but some features rely on device capabilities. Webcam and microphone testing require explicit permissions, and larger file operations depend on available memory. Browser-based downloads and full-screen timers can also behave differently between mobile and desktop, so check the individual tool's instructions.
Use the AG Tools contact page and include the exact page address, the inputs you used if they are not private, what result you expected and what actually happened. For accessibility problems, describe the device, browser and barrier you encountered. Do not send passwords, medical records, identity documents or private file contents as part of a bug report.
