Organized tools for real work
AltFTool is a free website with 3,947 online tools — converters, PDF and image editors, calculators, developer utilities, generators and browser games — that open straight in a browser tab with no account and no paid tier.
File tools (PDF, image, converters) run in your browser and the file is not uploaded. Tools that need live data or a model — AI tools, language checkers, lookups — send your input to an API, and say so on their own page. Ads are what keep the tools free.
