## Tools

- [Adobe RGB to HEX Converter](https://elysiatools.com/en/tools/adobe-rgb-to-hex-converter): Convert Adobe RGB color values to HEX format for web design
- [ASCII Table Reference](https://elysiatools.com/en/tools/ascii-table): Browse the complete ASCII character table (0–127) with decimal, hex, octal, binary, HTML entity, and control character names; filter by code or name
- [CMYK to HEX Converter](https://elysiatools.com/en/tools/cmyk-to-hex-converter): Convert CMYK color values to HEX for screen display
- [Color Code Validator](https://elysiatools.com/en/tools/color-code-validator): Validate Hex (#FFF, #RRGGBB), RGB/RGBA, HSL/HSLA color code syntax
- [Color Converter](https://elysiatools.com/en/tools/color-converter): Convert between different color formats
- [Color Expander](https://elysiatools.com/en/tools/color-expander): Expand 3-digit HEX codes to 6-digit codes (e.g., #FFF to #FFFFFF)
- [Color Gradient Generator](https://elysiatools.com/en/tools/color-gradient-generator): Generate smooth color gradients between multiple colors with customizable steps and formats
- [Color Opacity Adjuster](https://elysiatools.com/en/tools/color-opacity-adjuster): Adjust color opacity/alpha transparency with real-time preview and batch processing
- [Color Shortener](https://elysiatools.com/en/tools/color-shortener): Shorten 6-digit HEX codes to 3-digit codes (e.g., #FFFFFF to #FFF)
- [Color Space Converter](https://elysiatools.com/en/tools/color-space-converter): Convert a color between HEX, RGB, HSL, CIELAB, and Display-P3 with CSS-ready output and gamut checks.
- [Color Token Cascade Generator](https://elysiatools.com/en/tools/color-token-cascade-generator): Turn one primary hex color into a full design-token cascade with primary, accent, neutral, semantic tokens, CSS variables, and Style Dictionary JSON
- [CRC32 Checksum](https://elysiatools.com/en/tools/crc32-checksum): Compute the CRC32 checksum (IEEE 802.3 polynomial) of any text or raw bytes. Output as hex, decimal or binary. Accepts plain text (UTF-8) or raw bytes via hex/base64 input.
- [CSS Target Color Filter Generator](https://elysiatools.com/en/tools/css-target-color-filter-generator): Solve a CSS filter chain that closely reproduces a target hex color from a monochrome base color
- [ECharts Theme Token Extractor](https://elysiatools.com/en/tools/echarts-theme-token-extractor): Extract design tokens — colors, numbers, font sizes and strings — from an ECharts theme JSON and export them straight into your design system. Paste a theme object (the kind registered via echarts.init(dom, themeName)) and the tool walks every leaf, tagging each color (with optional named/rgb → hex normalization), spacing number, font size and string, then emits clean CSS variables, a Tailwind theme.extend config, Style Dictionary tokens.json, or SCSS variables. Bridges the gap between an ECharts visualization theme and Figma/CSS/Tailwind design tokens without copying each value by hand.
- [File Type Detector (Magic Number)](https://elysiatools.com/en/tools/file-type-detect): Identify a file by its magic-number byte signature, not the extension. Reads the uploaded file directly across ~70 types.
- [Hash Algorithm Comparator](https://elysiatools.com/en/tools/hash-algorithm-comparator): Hash the same input with MD5, SHA-1, SHA-256, SHA-512, BLAKE2b, and BLAKE3 at the same time and compare them side by side: output length, hex/Base64 digest, security status (broken / modern), and a relative speed benchmark. Great for teaching, choosing a hashing algorithm, or sanity-checking checksums.
- [Hex Editor (File Viewer)](https://elysiatools.com/en/tools/hex-editor): Upload any binary file and inspect it as a classic hex dump with offset, hex bytes, and ASCII columns (read-only)
- [HEX to Adobe RGB Converter](https://elysiatools.com/en/tools/hex-to-adobe-rgb-converter): Convert HEX color values to Adobe RGB format for professional design
- [HEX to CMYK Converter](https://elysiatools.com/en/tools/hex-to-cmyk-converter): Convert HEX color values to CMYK for printing with alpha channel support
- [HEX to HSL Converter](https://elysiatools.com/en/tools/hex-to-hsl-converter): Convert HEX color values to HSL for screen display

- [HEX to LAB Converter](https://elysiatools.com/en/tools/hex-to-lab-converter): Convert HEX color values to LAB for color management with alpha channel support
- [HEX to LCH Converter](https://elysiatools.com/en/tools/hex-to-lch-converter): Convert HEX color values to LCH for color management with alpha channel support
