FindUtils

FindUtils is a free online toolbox with 463 single-purpose tools for development, design, documents, calculations and everyday tasks. Format and validate JSON, test regex, minify CSS, format SQL, encode Base64 and URLs, generate passwords and QR codes, compress images, remove PDF metadata, add or remove PDF passwords, build UML diagrams and Markdown tables of contents. There is no sign-up and no install, and many tools process files right in your browser. You can save the tools you use most. For automation, a REST API (387 tools) and an MCP server (388 tools) let scripts and AI agents call the same tools, with llms.txt and an OpenAPI 3.1 spec.

Developers, designers, students and anyone doing everyday file and text tasks.

People who need a quick one-off tool (format JSON, merge a PDF, convert an image, encode text) usually hit sign-up walls, uploads to unknown servers or bloated apps. FindUtils offers 463 of them in one place, free, with no sign-up, and most processing happens in your browser.
