Base64 Encode PDF Files — Embed PDFs as Text
Quick Answer: Upload a PDF to get its Base64-encoded string. This is commonly needed when sending PDFs via JSON APIs, storing in text database fields, or embedding in data URIs for inline PDF viewing.
FAQ
Why would I Base64 encode a PDF?
APIs that accept JSON cannot include raw binary data. Base64-encoding the PDF lets you include it in a JSON string field for upload or storage.
How much larger is a Base64-encoded PDF?
About 33% larger. A 1MB PDF becomes roughly 1.33MB as Base64 text. Consider this when dealing with API payload size limits.
