Engineering Made Easy for Everyone

Developers and engineers constantly juggle between multiple online tools—calculating checksums, encoding data, converting formats, or debugging authentication tokens. Each website has its own quirks, and switching between them wastes valuable time.

CompuTools solves this by providing a unified platform with 24+ essential engineering utilities. All tools run directly in your browser, meaning your data stays on your machine—perfect for handling sensitive information.

Featured Tools: What Engineers Love Most

Based on real-world usage, here are the standout tools that developers reach for most frequently:

🔐 CRC Calculator — The #1 Tool for Data Integrity

The CRC Tool is CompuTools' most popular utility, and for good reason. Supporting 100+ CRC algorithms—from CRC-3 to CRC-64—it covers virtually every checksum standard you'll encounter:

  • Communication Protocols: Modbus RTU, Modbus ASCII, CAN Bus, HDLC
  • Automotive Standards: AUTOSAR CRC, SAE J1850
  • File Formats: CRC-32 (PNG, ZIP), CRC-32C (iSCSI, SCTP)
  • Network Protocols: Ethernet CRC, PPP, X.25
  • Embedded Systems: SMBus PEC, I2C CRC

Whether you're debugging Modbus communication, verifying file integrity, or implementing custom protocols, this tool handles it all with instant calculations.

📝 ASCII Converter — Universal Character Translation

The ASCII Converter transforms text between multiple representations instantly:

  • Text ↔ Decimal codes
  • Text ↔ Hexadecimal
  • Text ↔ Binary
  • Text ↔ Octal

Perfect for low-level debugging, protocol analysis, or understanding character encoding.

🔢 Number Base Converter — Beyond Simple Conversions

The Number Base Converter goes beyond basic binary-to-decimal conversions:

  • Supports any base from 2 to 36
  • Handles floating-point numbers with precision
  • Real-time conversion as you type
  • Batch conversion support

Ideal for programmers working with different number systems, memory addresses, or custom encoding schemes.

🎮 Quaternion / Euler Angle Converter — 3D Rotation Made Simple

For game developers, roboticists, and 3D graphics engineers, the Quaternion Converter eliminates rotation math headaches:

  • Quaternion ↔ Euler angles (XYZ, ZYX, and other rotation orders)
  • Interactive 3D visualization
  • Gimbal lock detection and warnings
  • Copy-paste friendly output formats

No more manual calculations or confusing coordinate system conversions.

🔒 File Hash Calculator — Verify Data Integrity

The File Hash Calculator computes multiple hash algorithms simultaneously:

  • MD5, SHA-1, SHA-256, SHA-512
  • Drag-and-drop file support
  • Text and file input modes
  • Instant hash comparison

Essential for verifying downloads, detecting file tampering, or generating checksums for distribution.

🔑 JWT Encoder & Decoder — Debug Authentication Instantly

The JWT Tool handles the complete JWT workflow:

  • Decode and inspect token structure (Header, Payload, Signature)
  • Create new tokens with custom claims
  • Verify HMAC signatures (HS256, HS384, HS512)
  • Expiration time validation with visual warnings

Stop struggling with base64 decoding—see your token claims instantly.

Six Categories, Endless Possibilities

CompuTools organizes its growing toolkit into intuitive categories, making it easy to find the right tool for any task:

Security & Hash

Ensure data integrity across your entire workflow. Calculate checksums using industry-standard algorithms for file verification, protocol debugging, and transmission validation. Decode and verify authentication tokens to debug API issues. Generate secure hashes for passwords, files, and sensitive data. Whether you're working with network protocols, embedded systems, or web APIs, these tools help you verify that your data remains uncorrupted and authentic.

Text & Encoding

Transform data between formats with precision and speed. Encode and decode using Base64, Base32, ASCII, and other common formats. Format and validate JSON, XML, and YAML for cleaner configuration files. Convert between different text representations, escape special characters, and compare text differences side by side. These utilities handle the everyday text manipulation tasks that developers encounter constantly—from API payloads to configuration files to log analysis.

Mathematical

Bridge the gap between number systems and measurement units. Convert between binary, hexadecimal, decimal, and octal representations for low-level programming and debugging. Transform between metric and imperial measurements across multiple categories including length, weight, temperature, pressure, and data sizes. Handle specialized calculations like quaternion-to-Euler conversions for 3D graphics and robotics applications. Perfect for engineers, scientists, and developers working across different domains.

Time & Date

Navigate the complexities of time representation across systems and timezones. Convert between Unix timestamps and human-readable dates instantly. Handle millisecond and second precision for precise timing requirements. Work with multiple timezone conversions to coordinate across global teams. Essential for debugging time-sensitive applications, analyzing logs, and scheduling tasks across distributed systems.

Generators

Create unique identifiers and secure credentials on demand. Generate RFC-compliant UUIDs for database records and distributed systems. Create cryptographically secure passwords with customizable complexity and strength analysis. Build QR codes for URLs, WiFi credentials, contact cards, and more with full color customization. These tools eliminate the need for manual generation and ensure your identifiers and credentials meet security standards.

Web Development

Streamline your frontend and API development workflow. Encode and decode URLs for proper web transmission. Convert between color formats (HEX, RGB, HSL, HSV, CMYK) and generate harmonious color palettes with accessibility contrast checking. Build HTTP requests visually and export ready-to-use code snippets in multiple programming languages including cURL, JavaScript, Python, Java, Go, and Rust. These tools accelerate the repetitive tasks that web developers face daily.

And Many More

Beyond the featured tools, CompuTools includes a comprehensive collection of utilities designed for everyday development tasks:

Text Processing — Convert between naming conventions (camelCase, snake_case, kebab-case), test regular expressions with live matching and capture groups, preview Markdown with GitHub Flavored Markdown support including tables, task lists, and automatic table of contents generation.

Data Format Conversion — Transform configuration files between YAML, JSON, and TOML formats seamlessly. Handle HTML entity encoding for safe web content display. Work with various encoding schemes for data transmission and storage.

Development Utilities — Compare text differences with multiple view modes, analyze and format structured data, and handle the countless small conversions that interrupt your coding flow.

Each tool is designed with the same philosophy: fast, private, and focused on solving real problems that developers face every day.
