Text & Data8
URL Encode/Decode
URL encoding converts special characters into a safe format using % followed by hexadecimal values, ensuring proper transmission in URLs. URL decoding reverses this process, restoring the original characters for correct interpretation.
Base32 Encode/Decode
Encodes data using a 32-character set (A-Z, 2-7), making it case-insensitive and suitable for human-readable applications. Decoding restores the original binary data.
Base58 Encode/Decode
A Bitcoin-friendly encoding that avoids visually similar characters (e.g., 0, O, l, I) to reduce confusion. Decoding converts it back to binary without padding.
Base64 Encode/Decode
Uses 64 characters (A-Z, a-z, 0-9, +, /) to encode binary data, commonly for web and email transmission. Decoding reverses it back to the original bytes.
Base91 Encode/Decode
A more efficient encoding with 91 printable ASCII characters, reducing size compared to Base64. Decoding retrieves the original data with high entropy.
