How it works
Encode: Converts text or file content into Base64. Maximum safe size for browser: ~50-100MB depending on memory.
Decode: Converts Base64 back to original text, image, PDF, audio, or video.
Example:
- Encode text: "Hello" → "SGVsbG8="
- Decode text: "SGVsbG8=" → "Hello"
- Encode file: image.png → Base64 string → decode → preview image
