Developer Tools

Encode text to Base64 or decode Base64 strings back to plain text instantly. Supports UTF-8 encoding for international characters. Commonly used for data transmission, embedding images in CSS, and email attachments.

Generate cryptographic hashes including MD5, SHA-1, SHA-256, and SHA-512 from any text input. Compare hashes to verify data integrity and detect file tampering. Essential for security professionals and developers.

Calculate cryptographic hashes of files including MD5, SHA-1, SHA-256, and SHA-512. Verify file integrity and detect modifications. Process files locally without uploading.

Convert colors instantly between HEX, RGB, RGBA, HSL, HSLA, CMYK, and HSV formats. Preview colors in real-time with a visual color picker. Indispensable for designers and front-end developers working on color schemes.

Convert Unix timestamps to human-readable dates in any timezone, or convert dates to Unix timestamps. Supports millisecond precision and multiple date formats. Essential for developers working with databases and APIs.

Generate RFC 4122 compliant version 4 UUIDs (Universally Unique Identifiers) for databases and applications. Create multiple UUIDs at once with guaranteed uniqueness. Industry standard for distributed systems and database primary keys.

Decode and inspect JWT (JSON Web Token) contents including header, payload, and signature. Verify token expiration and claims without secret key. Essential for debugging authentication systems and API integrations.

Parse and analyze URL components including protocol, host, port, path, query parameters, and fragment. Edit individual parts and reconstruct URLs. Debug complex URLs and understand their structure.

Capture screenshots of any webpage by entering its URL. Generate full-page screenshots or visible viewport only. Perfect for documentation, archiving, and design reviews.

Detect comprehensive browser, operating system, and device information. View screen resolution, plugins, and capabilities. Useful for debugging and user analytics.

Create JWT tokens with custom headers and payloads for testing authentication. Sign tokens with various algorithms. Debug OAuth flows and API authentication systems.

Create Markdown tables visually with an easy-to-use table editor. Add rows, columns, and align content without memorizing syntax. Copy formatted Markdown for documentation.

Decode UUID version and variant information from any UUID string. Extract timestamp from version 1 UUIDs. Understand the structure and origin of unique identifiers.
