Base64 is a binary-to-text encoding scheme that represents binary data in ASCII format. This tool can encode text, files, and images to Base64, or decode Base64 back to its original format. It supports both standard and URL-safe Base64 encoding.
Choose encode or decode operation, select your input type (text, file, or URL), enter your data, optionally enable URL-safe encoding, then click the process button. You can swap input and output for quick reverse operations.
URL-safe Base64 replaces characters that have special meaning in URLs:
• Standard: Uses + and / characters
• URL-safe: Uses - and _ instead
This prevents issues when Base64 data is used in URLs or filenames.
