Data Transfer tips

📦

Binary data (images, PDFs, executables) can't be reliably transmitted as raw bytes in text-based protocols. Base64 makes them safe.

📋

JSON does not support binary values natively. Encode your binary data as Base64 and include it as a string field in your JSON payload.

💡

Base64 encoded data is ~33% larger than the original. For large files, consider using a file URL or blob storage reference instead.

🔍

Use decode mode to inspect Base64 payloads from API responses, database blobs, or encoded config files.
