When to use Base64 PDFs
Base64 lets you embed a PDF inline in JSON payloads, data URIs or APIs without a separate file. Remember it increases size by roughly a third.
- Is there a size limit?
- Large PDFs produce very long strings and use more memory, but there is no fixed server limit.
- Are my files uploaded?
- No. Everything is processed locally in your browser, so your files never leave your device.
