Frequently Asked Questions
What is Base64 encoding?
Base64 is a way to encode binary data (like PDFs, images, or files) as a text string using only printable ASCII characters. It's widely used in APIs, email attachments, and data URIs.
When would I have a Base64-encoded PDF?
Base64-encoded PDFs often appear in API responses, email attachments encoded as MIME, database blobs, or embedded data URIs in web applications.
Is my PDF data safe?
Absolutely. All decoding is done in your browser using JavaScript. Nothing is uploaded to our servers. Your data stays completely private.
What if the output looks corrupted?
A corrupted output usually means the Base64 string is truncated or has invalid characters. Ensure you paste the complete, clean Base64 string without any extra spaces or line breaks.
