Common Base64 file workflows

- Share binary payloads as Base64 through systems that only accept plain text.
- Decode logged Base64 blobs back into files to inspect PDFs, images, and JSON payloads.
Helpful tips
- Base64 output is case-sensitive. Use copy buttons to avoid accidental character changes.
- Wrapped Base64 from logs often contains newlines; this tool strips whitespace automatically.
- Base64 increases payload size by around 33%, so avoid using it for very large assets when possible.
