Get document info Leave feedback
On this page
GroupDocs.Watermark can obtain a document’s basic information — file type, page count, and size — before you process it. The get_document_info() method works on a Watermarker opened from either a file path or a stream.
from groupdocs.watermark import Watermarker
def get_document_info():
with Watermarker("./sample.docx") as watermarker:
info = watermarker.get_document_info()
print("File type:", info.file_type)
print("Pages:", info.page_count)
print("Size, bytes:", info.size)
if __name__ == "__main__":
get_document_info()

A document can also be opened from any readable stream:
import io
from groupdocs.watermark import Watermarker
def get_document_info_from_stream():
with open("./sample.docx", "rb") as f:
stream = io.BytesIO(f.read())
with Watermarker(stream) as watermarker:
info = watermarker.get_document_info()
print("File type:", info.file_type)
print("Pages:", info.page_count)
print("Size, bytes:", info.size)
if __name__ == "__main__":
get_document_info_from_stream()
sample.docx is the sample file used in this example. Click here to download it.
File type: Docx (.docx) - WordProcessing

Use case: Validate documents before processing — for example, reject unsupported file types or confirm page limits.
