Is the pdf to base64 converter private?
Yes. The PDF bytes are encoded without parsing or changing pages, fonts, signatures, or document metadata. All processing happens locally in your browser — nothing is uploaded to our servers.

No registration, watermark, queue, or server upload is required.
Use Base64 wisely
Base64 is ideal for text-only APIs, small embedded assets, test fixtures, and portable documents. It increases payload size, so external files are usually better for large public assets.
Frequently asked questions
Will PDF signatures and metadata stay intact?
Yes. The PDF is encoded as raw bytes without parsing or modifying the document structure.
Why embed a PDF as Base64 in JSON?
Some APIs and legacy systems only accept text payloads. Base64 lets you transport binary PDF data inside JSON or XML fields.
When should I use Base64 for PDF documents?
Use it when a text-only channel or API must carry binary data, or when a small PDF documents asset needs to live inside a self-contained document. Prefer separate files for large, cacheable public assets.
