PDF to Base64 Converter — Encode PDF Files

Quick Answer: Upload a PDF file to convert it to a Base64-encoded string. The output can be used in JSON API payloads, stored in database text columns, or included in MIME email attachments.

FAQ

How do I send a PDF via a JSON API?

Base64-encode the PDF and include the string in a JSON field. The receiving API decodes it back to binary. Most APIs document the expected field name.

Can I view a Base64-encoded PDF in the browser?

Yes. Use a data URI: data:application/pdf;base64,[encoded-string]. Paste it in the browser address bar or an iframe src.
