What is Clean.tools?
Clean.tools is a collection of free, browser-based utilities for working with images, media, and development tasks. Every tool runs entirely on your device using modern browser APIs. Your files are never uploaded to a server, and there is nothing to install or sign up for.
Whether you need to resize an image, crop a photo, compress a file, convert a PNG to SVG, pick a color, generate a password, create a QR code, convert units, convert time zones, calculate compound interest, build cron expressions, run a Pomodoro timer, or track lap times with a stopwatch, Clean.tools handles it locally in seconds. It works on desktop and mobile, on any modern browser.
Work with AI agents or scripts? Connect Clean.tools in one command. A REST API and MCP server expose 23 of these tools, plus the @clean-tools/mcp npm package.
