How Do These Online Converters Operate Behind the Scenes?

Generally speaking, a free online PDF to XML converter works in a few steps, though the precise procedure may differ based on the complexity of the tool and the type of PDF:

1. File Upload: The user uploads the PDF file to the converter's web server. When selecting a tool, the security of the upload process is crucial.
2. First Analysis & Pre-processing: The program examines the structure of the PDF.
   • The converter aims to directly extract text, fonts, and layout information that are embedded in text-based PDFs, also known as native PDFs. It finds structures and patterns that can be converted into XML tags, such as headings, tables, and paragraphs.
   • OCR (Optical Character Recognition) technology is used for image-based PDFs, also known as scanned PDFs when the PDF is derived from a scanned document or image. After scanning the image, OCR identifies words and characters and transforms them into machine-readable text. The quality of OCR has a significant impact on the final XML output.
3. Structure Recognition & Mapping: The converter recognizes logical structures (such as tables, lists, paragraphs, and headings) in the PDF content. These structures are then mapped to the proper XML elements and attributes. Specific sophisticated tools enable users to utilize templates for particular document types (such as invoices) or create custom mapping rules.
4. XML Generation: The tool creates the XML code using the extracted data and the identified structure. To represent the data from the PDF, a hierarchical tree of tags must be made.
5. Output & Download: The user can then download the generated XML file.
