Private Base64 Encoder & Decoder
Encode and Decode Text or Files Locally
Base64 is widely used for encoding data in web development. Base64Diet provides a privacy-first utility to encode strings or files and decode Base64 back to UTF-8 text or raw binary data. All encoding and decoding happen on your device, preventing sensitive tokens, API payloads, or images from leaving your sandbox.
Encode and Decode Base64
- Step 1: Paste text or upload a file to encode.
- Step 2: Paste a Base64 string to decode.
- Step 3: The tool automatically detects if the decoded output is binary or text.
- Step 4: Copy results or download them as text or binary files (.bin).
Frequently Asked Questions
Q: Can I decode binary files like images from Base64?
A: Yes. When decoding, if the tool detects binary data, it prepares a downloadable binary file (.bin) instead of showing scrambled characters.
Q: Is Base64 secure for encryption?
A: No. Base64 is an encoding format, not encryption. Anyone can decode it easily, so do not use it to secure passwords without cryptographic layers.
