Base64 to ZPL decoder
Paste the Base64 string from a carrier API and get the ZPL back, ready to open in the editor or send to the printer. Carrier APIs often return labels this way, and the decoding happens in your browser.
How to use it
- Paste the Base64 string.
- Copy the ZPL or open it in the editor to see the label.
Questions
Why do APIs send ZPL as Base64?
It lets a label travel safely inside JSON or XML. It's the same text, encoded.
It decoded to something unreadable
The label may be a PNG or PDF in Base64 and not ZPL. A real ZPL label starts with ^XA.
Is it uploaded?
No. It is decoded in your browser.
