Encode/decode: Base64/URL/Unicode/Hex/HTML, MD5/SHA hash, UUID/GUID. Offline, 10 languages. Encoding Tool A powerful encoding/decoding tool that supports multiple encoding formats, hash algorithms, and utility tools. Automatically detects system language and supports multi-language switching. Main Features ① URL Encoding/Decoding Supports URL encoding operations, converting special characters to URL-standard encoded formats to ensure URL validity and security, avoiding request issues caused by special characters. Can decode encoded URLs, restoring encoded characters to their original form for easy viewing and modification of original URL information. ② Base64 Encoding/Decoding Provides Base64 encoding functionality, converting binary data, text, etc. to Base64 format, commonly used for transmitting longer identifiers, encrypted data, etc. in HTTP environments to ensure data transmission integrity. Allows users to decode Base64-encoded data, restoring it to original data or text. ③ HTML Entity Encoding/Decoding Supports HTML entity encoding and decoding, converting HTML special characters to entity codes (e.g.,
