Base64 Encoder & Decoder with Data Formatter FAQ
What is the Data Formatter feature?
The Data Formatter automatically recognizes and formats your decoded Base64 data. It supports JSON formatting, XML conversion, YAML output, HTML tables, and PHP Serialized data parsing. When you decode Base64 data, the tool detects the format (e.g., PHP Serialized arrays, JSON objects) and offers to format it in readable structures. Perfect for developers working with API responses, database exports, or configuration files.
How does PHP Serialized data formatting work?
Our tool includes a complete PHP Serialized parser that converts PHP serialized arrays into readable JSON, XML, YAML, or table format. Simply decode your Base64 string, and the formatter will automatically detect PHP serialized data (format like a:3:{i:0;s:5:"value";...}) and convert it to structured, human-readable formats. This is especially useful for analyzing PHP session data, cache contents, or database exports.
What output formats are supported?
The Data Formatter supports 6 different output formats: (1) JSON formatted - beautiful, indented JSON with 2-space formatting, (2) JSON compact - single-line JSON for efficiency, (3) XML - valid XML with proper structure and escaping, (4) YAML - human-readable YAML format, (5) HTML Table - visual tabular representation, and (6) PHP Serialized formatted - original format with JSON interpretation. All formats can be copied to clipboard or downloaded as files (.json, .xml, .yaml, .html, .txt).
Can I convert Base64 to JSON automatically?
Yes! When you decode Base64 data that contains JSON or PHP serialized structures, our Data Formatter automatically detects this and offers JSON formatting. The formatter recognizes JSON strings, PHP serialized arrays, and even query strings, converting them all to clean, formatted JSON. This makes it perfect for API development, debugging web services, or analyzing data exports.
What is Base64 and what is it used for?
Base64 is an encoding method that converts binary data into ASCII characters. It is commonly used for email attachments (MIME encoding), embedding images in HTML/CSS (Data URIs), transmitting binary data over text-based protocols, API authentication and token creation, and configuration files and data export.
Is the processing of my files secure?
Absolutely secure! Our tool performs all processing client-side in your browser, including the data formatting. This means your files and data are never sent to our servers, all data remains on your computer, no storage or logging of content, and it works offline after initial load. Even sensitive data like PHP serialized database exports are processed entirely in your browser.
Which file types and sizes are supported?
All file types are supported: Images (JPG, PNG, GIF, SVG, WebP, etc.), Documents (PDF, DOC, XLS, TXT, etc.), Archives (ZIP, RAR, 7Z, etc.), Audio/Video (MP3, MP4, AVI, etc.), and Code files (HTML, CSS, JS, PHP, JSON, XML, etc.). Size limitations: Up to 50MB per file (browser-dependent). For larger files, please use batch processing. The Data Formatter works best with text-based data up to 10MB.
How do I export formatted data?
After formatting your decoded Base64 data, you have two export options: (1) Copy formatted - Copies the formatted output directly to your clipboard for immediate use in your code editor or application, and (2) Download formatted - Downloads the data as a file with the appropriate extension (.json for JSON format, .xml for XML, .yaml for YAML, .html for table view, .txt for text). The filename is automatically generated with a timestamp.
What does "URL-Safe Base64" mean?
URL-Safe Base64 is a variant that can be used in URLs without causing problems: Standard Base64 uses +, / and = characters, URL-Safe Base64 replaces + with -, / with _ and often removes padding (=). Ideal for JWT tokens, URL parameters and filenames, prevents encoding problems in URLs.
How do I use Base64 for images in HTML?
Base64-encoded images can be embedded directly in HTML (Data URI):
<img src="data:image/png;base64,iVBORw0KGgoAAAANS..." alt="Description">Advantages: No separate HTTP requests for images, images are directly contained in the HTML code, works offline without external dependencies. Disadvantages: Increases HTML file size by about 33% compared to the original image file.
Can I use this tool for API development?
Absolutely! The Base64 Encoder/Decoder with Data Formatter is perfect for API development. Use it to: Decode Base64-encoded API responses and format them as JSON, Convert PHP serialized data from legacy APIs to modern JSON format, Test Base64-encoded authentication tokens, Format and analyze webhook payloads, Debug REST API responses, and Export API data in various formats (JSON, XML, YAML) for documentation or testing.
Does the tool support keyboard navigation and accessibility?
Yes, completely! Our tool is developed according to WCAG 2.1 AA standards: Keyboard Navigation (Tab, Enter, Space, Arrow keys), Screen Reader (complete ARIA labels and descriptions), Focus Indicators (clearly visible focus frames), Contrast (at least 4.5:1 contrast ratio), and Shortcuts (Ctrl+V for Paste, Ctrl+C for Copy).
