JSON Prettier
Format & beautify
Paste messy or broken JSON and get it clean and indented automatically, with syntax highlighting. Minify, copy, done.
JSON Verify
Validate & locate errors
Check if your JSON is valid in one click. If it's broken, see the exact line and column with a pointer right at the problem.
JSON Compare
Diff two documents
Compare two JSON documents — key order and formatting ignored. If they differ, see exactly which fields changed, by path.
Base64
Encode & decode
Convert text to Base64 or decode it back in one click. Full Unicode and URL-safe support, with live conversion as you type.
Auth Header
Encode & decode
Build or read an Authorization header. Encode a Bearer token or Basic credentials, or paste an existing header to decode the JWT payload or user:pass.
JSON to TS
Generate types
Paste JSON and get clean TypeScript interfaces instantly. Infers nested types, merges array shapes, and marks optional & nullable fields.
Object to JSON
Object dump → JSON
Turn a logged object / map dump with unquoted keys & values into valid JSON — or a .env file, headers, or query string. Handles nesting, arrays, and types.
SSH Keygen
Generate & download keys
Create an Ed25519 or RSA SSH key pair right in your browser and download it as a ready-to-use .zip, with copy-paste steps for where to put the files.
Image Paste
Upload → WebP → short URL
Drop an image, get a lightweight WebP and a short shareable URL with a live preview. Converted in your browser before upload — the original never leaves your device.
