Flatten PDF on Windows

Flattening a PDF is ideal for finalizing documents, as it locks elements like images, watermarks, signatures, and annotations, preventing others from copying or editing them. This is especially useful for sharing and archiving important documents without risking accidental changes. Follow this guide to learn how to easily flatten your PDFs on Windows using UPDF.

Start by opening the PDF in the editor and extending the menu for the Save icon on the top right side.

• From the menu, click on the Save as Flatten option to continue to the following pop-up.

• In the new window, you’ll see different options for flattening, which include:

Watermarks: This option will disallow users to edit, copy, or delete the watermark from the PDF documents.

Cropped Pages: After cropping the PDFs, flattening the file with this option will prevent others from accessing and recovering the cropped content.

Comments: This option allows you to flatten all the comments added in your PDF document.

Forms: If you go for this option, it flattens all the form fields. This can save you from letting other users edit the information or copy it.

• With the options you need selected, click Save As and continue on the next pop-up to save the name and location of the new PDF file. On setting these details, select Save to completely flatten your PDF.
