Frequently Asked Questions
- Which config files work with this tool?
- Any JSON configuration file: package.json, tsconfig.json, .eslintrc.json, babel.config.json, VS Code settings, AWS CloudFormation templates, and more.
- Is Base64 encoding the same as encryption?
- No. Base64 is encoding, not encryption. It is easily reversible without any key. Never use Base64 for security — use it only for data transmission compatibility.
- What characters does Base64 use?
- Base64 uses 64 printable characters: A-Z (26), a-z (26), 0-9 (10), + and /. The = character is used for padding at the end.
About This Tool
Configuration files are at the heart of modern software development — from package.json and tsconfig.json to VS Code settings and cloud infrastructure templates. This Base64 Encoder for Config Files is tailored for processing BASE64 configuration files with the precision and care they require. Configuration files often contain comments (in formats that support them), version-specific settings, and carefully structured hierarchies that must be preserved during formatting. The tool processes these files while maintaining all data integrity, ensuring that indentation reveals the logical structure of configuration sections, nested settings, and conditional values. Whether you are cleaning up auto-generated configuration, merging settings from multiple sources, or preparing config files for documentation, this tool handles the task reliably.
What is Base64 Encoder / Decoder?
A Base64 encoder/decoder converts binary data or text into Base64 representation and back. Base64 encoding represents binary data using 64 printable ASCII characters (A-Z, a-z, 0-9, +, /), making binary content safe for transmission in text-based systems. It is used ubiquitously in web development: data URIs for embedding images in HTML/CSS, encoding binary data in JSON APIs, encoding credentials in HTTP Basic Authentication headers, encoding JWT (JSON Web Tokens) payloads, encoding email attachments in MIME format, and transmitting binary files through text-only protocols. This tool handles UTF-8 text encoding correctly, supporting international characters and emoji in both encoding and decoding operations.
How to Use This Tool
- Paste plain text and click Encode to Base64.
- Paste a Base64 string and click Decode from Base64.
- Copy the encoded or decoded result.
Common Use Cases
- Formatting package.json for readability
- Cleaning up tsconfig.json and eslint configs
- Processing VS Code settings.json files
- Normalizing docker compose JSON overrides
