Web Developer Utilities
Stop Googling for random developer tools. Our suite provides instant hashing, encoding, minification, and ID generation directly in your browser without exposing your source code or keys to external servers.
URL Encoder Decoder
Use NewTools to encode and decode URL text directly in your browser. Encodes or decodes URL components and query strings with friendly validation errors.
Base64 Encoder Decoder
Use NewTools to encode and decode Base64 text directly in your browser. Handles Unicode text safely for Base64 encoding and decoding in the browser.
UUID Generator
Use NewTools to generate UUID v4 values directly in your browser. Uses browser crypto to generate one or many random UUID v4 identifiers.
Hash Generator
Use NewTools to generate SHA hashes directly in your browser. Creates SHA-1, SHA-256, SHA-384, or SHA-512 hashes with Web Crypto.
HTML Minifier
Use NewTools to minify basic HTML directly in your browser. Basic browser-side minifier for comments and whitespace; it is not a full build optimizer.
CSS Minifier
Use NewTools to minify basic CSS directly in your browser. Basic browser-side minifier for comments and spacing around symbols; it is not a full build optimizer.
The Developer's Swiss Army Knife
When you are in the flow state of coding, switching contexts to write a quick Python script just to URL-encode a string or generate a UUID breaks your momentum. Our web developer tools are designed to be lightning-fast bookmarks you can rely on.
Secure by Default
If you are generating an MD5 hash of a user's password for testing, or decoding a Base64 JSON Web Token (JWT) containing sensitive claims, you cannot trust random websites. Because our developer tools are built using JavaScript that runs locally on your machine, your secrets are completely safe.
