Binary to Base64 Converter

Binary strings—a sequence of 0s and 1s—are the most atomic representation of data in computers. Yet, many transport layers and APIs only support text-safe formats. Base64 encoding translates every 3 bytes (24 bits) into 4 ASCII characters (using A–Z, a–z, 0–9, +, /), ensuring safe passage across text-only channels. The Binary to Base64 converter groups your input bits into bytes, assembles a byte array, and then applies the standard Base64 algorithm with optional URL-safe transformations.

This tool supports continuous bitstreams or space-delimited bytes, auto-pads incomplete final bytes, and can output standard or URL-safe Base64 with or without padding.

Every 8 bits form one byte (0–255). The converter pads the final byte with leading zeros if fewer than 8 bits remain. Base64 then processes bytes in groups of three, mapping them to four-character blocks.

Input must contain only '0' and '1' characters, optionally separated by spaces or newlines. Total bit length should be a multiple of 8 or the converter will pad the final group with zeros.

A Base64-encoded ASCII string, including padding (‘=’) by default. URL-safe variants and padding omission are configurable.

1. **Sanitize**: Remove non-bit characters. 2. **Group**: Split into 8-bit segments, pad last if needed. 3. **Byte Array**: Convert each segment to a byte (0–255). 4. **Base64 Encode**: Apply standard or URL-safe Base64. 5. **Return**: Provide the final string.

IoT devices often emit bit-level sensor flags; this converter transforms those bits into Base64 for web API ingestion. Security protocols specify bit flags that need to be transmitted in text-based handshakes— Base64 encoding ensures compatibility.

In digital art and cryptographic puzzles, artists encode messages at the binary level and then wrap them in Base64; this converter reverses that workflow for publishing or analysis.

Bit-level parsing is linear but can be CPU-intensive for very long streams (>1M bits). Offload to Web Workers or server-side scripts if performance is critical.

Limit input length to avoid CPU exhaustion. Validate that only 0s and 1s are present before conversion to prevent unexpected behavior.
