UtilityKit is a web-based collection of more than five hundred free developer and productivity tools, covering everyday tasks like text processing, calculations, data conversion, image editing, PDF handling and audio utilities. It is aimed at developers, content creators and anyone who needs a quick utility, such as counting words or formatting JSON, without installing software.
Tools are organized into categories, including Text Tools, Developer Tools, Calculators, Generators, Data Conversion, Image Tools, PDF Tools and Audio Tools, and each one is used directly on the site with no account required. Examples include a word counter that analyzes text metrics and a JSON formatter that structures code data. For privacy-sensitive tasks such as stripping metadata from an image, processing appears to happen in the browser rather than on a server.
UtilityKit is free to use, with no sign-up requirement and no paid tiers or subscriptions described on the site.
