Base64 converts binary data into ASCII text, making it safe for transmission across text-only protocols like email, JSON, and XML without data corruption or loss.
While not encryption, Base64 provides basic data obfuscation and prevents special character issues during data transfer between different systems and platforms.
Select between Text Input for quick encoding/decoding or File Input for processing documents, images, or any binary files up to 25MB each using drag-and-drop functionality.
Customize your output with options like line breaks for readability, data URI prefixes for web embedding, or custom headers for better organization and identification.
Click "Encode to Base64" for conversion to text format or "Decode from Base64" to restore original files from Base64 strings. Our tool handles both directions seamlessly.
Copy encoded text directly to clipboard, download individual files, or use batch download for multiple files in a convenient ZIP archive for efficient workflow management.
Process plain text or upload files including images, documents, PDFs, and any binary format with intuitive drag-and-drop convenience.
Encode or decode multiple files simultaneously and download all results in a single ZIP file for maximum efficiency and time savings.
Add line breaks for readability, data URI prefixes for web use, or custom headers for better organization and professional presentation.
All processing happens locally in your browser - your files never leave your computer, ensuring maximum security and data protection.
