ToolHub is a free collection of online tools built to make everyday tasks quick and easy — counting words, converting formats, generating QR codes, compressing images, checking JSON and much more.
Privacy by design
Every tool on ToolHub runs 100% in your browser. Your text, files and data are processed on your own device and are never uploaded to any server. That means nothing you type, paste or drop into a tool is stored, tracked or sold.
Free forever
All tools are free to use, with no sign-up and no limits. The site is supported by advertising, which lets us keep everything free for everyone.
