PUBLIC / LOCAL TOOLS
Tools that actually work.
Three practical features, with nothing to install. Text and selected files are processed on your device; this website does not upload them.
All calculations run inside your browser. Fields and selected files are not sent to our server.01 · JSON
Validate structure and neatly format JSON.
02 · Base64 / UTF-8
Encode and decode multilingual text using UTF-8.
03 · SHA-256
Compute the checksum of a text or local file.
When a file is selected, the tool hashes the file instead of the text.
