FAQ
What is Base64 encoding?
Base64 is a method to convert binary data (like PDF files) into text format. This text can be embedded in HTML, JSON, XML, or transmitted over text-based protocols. The encoded string is about 33% larger than the original binary.
What format should I choose?
Raw Base64 for API requests and databases. Data URI for embedding in src attributes. HTML Embed for iframe/embed tags. JSON for web APIs and structured data.
Is my PDF safe?
100% safe! Encoding happens entirely in your browser. Your PDF is never uploaded to any server.
