Frequently Asked Questions

What is Base64?

Base64 is a way to represent binary data (like PDFs, images, or videos) as text. This ensures safe transmission over systems that only handle plain text, such as JSON or email.

What is a Base64 string for a PDF?

A Base64 string for a PDF is a text representation of the PDF's binary data. Since PDFs are originally binary files (made of 1s and 0s), they can't be safely transferred or embedded in text-based systems like HTML, JSON, or email. Base64 encoding converts this binary data into a long, readable string of characters, making it easy to store or transmit the PDF file in a text format. Our tool decodes this string back into a usable PDF file.

How do I convert a PDF to Base64?

You can easily convert a PDF to a Base64 string using our dedicated tool for that purpose. Just head over to our PDF to Base64 Converter, upload your PDF file, and the tool will instantly provide you with the Base64-encoded text. This is useful for embedding a PDF directly into web pages or for secure data transfer.

Can I use this tool to decode a Base64 to Image?
