Base64 encoding is used to encode binary data, such as a PDF file, into an ASCII string format that is compatible with systems that can only handle text. For example, email attachments and binary uploads in HTML forms are converted and transmitted as Base64 encoded data.

The C# code snippet below shows how easy it is to save as any LEADTOOLS image format, including PDF, with Base64 encoding.

While PDF files are flexible and portable, unfortunately they are not always searchable. In fact, a very common request is for the ability to parse text from PDFs. Luckily, LEADTOOLS OCR Engine makes extracting searchable text from PDF files a breeze. LEAD’s AI-enhanced engine can accept any PDF (searchable or not) and extract the text from it, using OCR where necessary. After extraction LEADTOOLS can save that information to a text file, a searchable PDF file, or any of our other 150+ supported document formats.

Earlier this week, we wrote about our latest white paper and CodeProject article on the LEADTOOLS Document Converter and Document Viewer. If you haven't already, it's worth a read to see just how easy it is to create an amazing document viewing solution for .NET and HTML5 / JavaScript.

If you simply can't wait another second to get your hands on this technology, you should try our live online Document Viewer demo! This HTML5 Zero-footprint application shows off all the amazing features of this new viewer framework including:

There are many reasons why you might want to convert to or from a PDF document. Perhaps you need to make a PDF editable or text searchable. Or maybe you would prefer a PDF to be a DOC or DOCX file, but you don't want to copy/paste the text or lose the original formatting. You might even need to batch convert a ton of PDFs in the same way. Good news! The LEADTOOLS Document Converter SDK is an easy to integrate tool able to handle all of your document and image conversion needs.
