Convert BDOC to PDF

Understanding BDOC and PDF file formats

BDOC is a digital signature container format widely used in Estonia and other Baltic countries for secure document signing. It is based on XML and ZIP technologies, allowing multiple files and digital signatures to be bundled together. PDF (Portable Document Format) is a universal file format developed by Adobe, designed for reliable document exchange and presentation, preserving layout and content across platforms.

Why convert BDOC to PDF?

Converting a BDOC file to PDF is useful for sharing signed documents with recipients who may not have specialized BDOC viewing software. PDF files are widely supported and easier to view, print, and archive.

How to convert BDOC to PDF

Since BDOC files are containers, you must first extract the signed documents (usually in DOC, DOCX, or PDF format) from the BDOC archive. If the contained files are not already in PDF, you can then convert them to PDF.

Step-by-step conversion process

1. Extract files from BDOC: Use a BDOC viewer or signature verification tool such as DigiDoc4 Client (by SK ID Solutions) to open the BDOC file and extract its contents.
2. Check file format: If the extracted file is already a PDF, you can use it directly. If it is another format (e.g., DOCX), proceed to the next step.
3. Convert to PDF: Open the extracted file in its native application (e.g., Microsoft Word for DOCX) and use File → Export → PDF or File → Save As → PDF to create a PDF version.

Recommended software for BDOC to PDF conversion

• DigiDoc4 Client (Windows, macOS, Linux): Official tool for opening and extracting BDOC files. Download DigiDoc4 Client.
• Microsoft Word or LibreOffice: For converting DOC/DOCX files to PDF after extraction.
• Online converters: If you have extracted files in a common format, use trusted online PDF converters like iLovePDF or Smallpdf.

Important considerations

• BDOC files may contain multiple documents and digital signatures. Converting to PDF will not preserve the digital signature in the PDF itself, but you can keep the original BDOC for legal purposes.
• Always verify the authenticity of the BDOC file before extracting and converting its contents.
