GroupDocs.Comparison for Python via .NET can return the following information about a document without performing a comparison:
file_type— the document file type (PDF, Word, Excel, PowerPoint, image, etc.).page_count— number of pages.size— file size in bytes.pages_info— per-page information.
from groupdocs.comparison import Comparer
def get_document_info():
with Comparer("./source.docx") as comparer:
info = comparer.source.get_document_info()
print(f"File type: {info.file_type.file_format}")
print(f"Number of pages: {info.page_count}")
print(f"Document size: {info.size} bytes")
print("\nDocument info extracted successfully.")
if __name__ == "__main__":
get_document_info()
source.docx is the document used in this example. Click here to download it.
File type: Microsoft Word Document
Number of pages: 1
Document size: 26611 bytes
Document info extracted successfully.

Comparer.source.get_document_info() is one of three ways to read information about a document without running a full comparison:
| What you need | Use |
|---|---|
| File type, size, page count of a specific document | This page |
| The list of every supported format at runtime | Get supported file formats |
| Visual thumbnails of selected pages | Generate document pages preview |
Pair get_document_info() with the format-list to validate inputs early in a pipeline (e.g., reject anything outside an allowlist), and use page previews to give end users a quick visual preview before committing to a full diff.
- Get supported file formats — enumerate supported types at runtime.
- Generate document pages preview — render page thumbnails.
- Specify file type for comparison manually — when the inferred type is wrong.
