2. Base64 Encoder/Decoder
Encode and decode Base64 strings instantly
Base64 encoding is essential for data transmission, embedding images in CSS/HTML, and working with APIs that require encoded data.
Common Use Cases:
- • Embedding images in CSS (data URLs)
- • API authentication tokens
- • Email attachment encoding
- • Binary data transmission
3. Code Beautifiers
Format HTML, CSS, and JavaScript code
Clean, well-formatted code is easier to read, debug, and maintain. Code beautifiers automatically format your code with proper indentation and spacing.

|---|---|---|
| MD5 | Low | File checksums |
| SHA1 | Medium | Git commits |
| SHA256 | High | Passwords, certificates |
5. URL Encoder/Decoder
Handle URL encoding and special characters
URLs can't contain certain characters. URL encoding converts special characters into a format that can be transmitted over the internet safely.

JSON Web Tokens (JWT) are widely used for authentication and information exchange. Decode JWTs to inspect claims or encode data into JWT format.
Decode JWT
- • View token payload
- • Check expiration
- • Inspect claims
- • Debug authentication
Encode JWT
- • Create test tokens
- • Generate mock data
- • API testing
- • Development workflows
7. Code Minifiers
Compress code for production
Minification removes unnecessary characters from code without changing functionality. Essential for optimizing web performance and reducing bandwidth usage.
Performance Benefits:
- • Faster loading: Smaller file sizes
- • Reduced bandwidth: Lower hosting costs
