About This Tool
What is 编解码器?
A tool for encoding and decoding text using various formats including Base64, Base32, Hex, and ASCII85. Commonly used in web development, API communication, and data transmission. All conversions happen in your browser, so your data never leaves your device.
How to Use
- Select the encoding format (Base64, Base64URL, Base32, Hex, ASCII85) from the tabs.
- Enter the text you want to convert in the input area.
- Click 'Encode' or 'Decode' to perform the conversion.
- Use the copy button to copy the result to your clipboard.
Key Features
- Supports 5 encoding formats: Base64, Base64URL, Base32, Hex, ASCII85
- Real-time encoding and decoding
- One-click result copying
- Browser-based processing for privacy protection
Tips
- Base64 is most commonly used for email attachments and API data transmission.
- Base64URL replaces + and / with - and _ for safe use in URLs.
- Hex encoding is widely used for color codes, MAC addresses, and binary data representation.

Frequently Asked Questions
Base64和Base64URL有什么区别？▼
标准Base64使用A-Z、a-z、0-9、+和/。Base64URL将+替换为-，/替换为_，使编码字符串在URL和文件名中安全使用。Base64URL还省略=填充字符。当编码数据要包含在URL或HTTP头中时使用Base64URL。
Base64编码等同于加密吗？▼
不。Base64是编码方案而非加密。它将二进制数据转换为文本格式以便安全传输，但不提供安全性——任何人都能解码。切勿使用Base64保护敏感数据。实际数据保护请使用AES或RSA等加密算法。
何时使用Hex编码vs Base64？▼
Hex将每个字节表示为两个字符（0-9、A-F），输出大小是输入的两倍。Base64更节省空间，输出约比输入大33%。调试、颜色代码和需要逐字节可读性时用Hex。数据传输中需要更小尺寸时用Base64。
