What is a PDF to Base64 encoder?
A PDF to Base64 encoder reads a PDF file and converts it into raw Base64 or an application/pdf data URL. This is useful for API tests, document fixtures, and debugging encoded document payloads.
How to use it
- Upload a PDF file.
- Choose raw Base64 or data URL output.
- Copy the encoded PDF string.
Example
Input: contract.pdf
Output: data:application/pdf;base64,JVBERi0x...
Common mistakes
- PDF Base64 strings can be very large.
- Some APIs reject the
data:application/pdf;base64,prefix and expect raw Base64 only. - Base64 does not protect the document contents.
