How to Easily Flatten a PDF in Few Steps
A flattened PDF refers to a document only with one single layer and is thus printing-friendly. Interactive elements, like forms or annotations, are image layers on a document. They can be easily modified by others. Flattening a PDF implies removing transparency, combining several layers into a single unit, and locking comments, form fields, layers, or any other interactive components in PDFs.
If you use programs like Adobe InDesign or Photoshop to create a PDF from layered documents, the PDF is bound to have several layers, some of which are transparent and invisible. A printer, on the other hand, can only recognize and print visible onscreen content, not all visual elements from several layers. Follow the tutorial below to figure out how to flatten a PDF.
Flatten a PDF on Windows
Although the steep subscription fee and sophisticated functionality, Adobe still holds a safe lead in the document management industry. Adobe Acrobat is a comprehensive PDF program with a wide spectrum of features to ease PDF-related tasks. Regarding how to flatten a PDF on Windows, the software offers two intuitive methods to convert a PDF into a flattened document,
By Adobe Acrobat Reader
Users of Adobe Reader can flatten a PDF document in diverse ways. The most effortless way, however, is to utilize the “Print” feature to save this multi-layered document into a flattened one. Here’s how to do it:
Step 1: Download and install Adobe Acrobat on your device;
Step 2: Launch the program and upload the PDF that needs to be flattened;
Step 3: Navigate to the main taskbar, and click File > Print. In the drop-down menu of Printer, choose Adobe Printer;
Step 4: Remember to select Document and Markups in the Comments & Forms box. Meanwhile, Summarize Comments is available as well to flatten this PDF. When ready, tap on the Print button.
By Adobe Acrobat Pro DC on Windows
If you are running the Adobe Acrobat DC, an advanced version of the Reader, the steps may be somewhat different. Let’s take a closer look at how to flatten a PDF using the Acrobat:
Step 1: Download the program from the official website;
Step 2: Start the software and load up a PDF to the workstation;
Step 3: Go click Tools on the ribbon, then choose Print Production;
Step 4: When a new window appears, locate the Flattener Preview. Once you finish all the settings, click Apply to make this PDF a flattened one.
The truth to be told, the process of flattening a PDF is to transform the data stored in a PDF into a flat image. Among all image formats, JPEG is the optimal one. SwifDoo PDF is an all-around PDF converter that can perform multiple file conversions, including PDF to JPEG. Here’s a quick look at flattening a PDF by converting this PDF to a JPEG:
Step 1: Go download SwifDoo PDF from the official website and Microsoft AppSource;
Step 2: Install and launch the program, then upload a PDF to the workspace;
Step 3: Click Convert > PDF to Image. When the converter pops up, select JPG in the drop-down menu of Format. Hit the Convert button to save your new flattened file, a JPEG file.
If all you need is a flattened PDF, then convert the JPEG file back to PDF using SwifDoo PDF. Admittedly, this approach is not straightforward but workable. An image file is not editable unless you utilize professional photo editors to make edits. Otherwise, all interactive elements within will be flattened without any layers. It is indeed a static image file.

Step 1: Start the Preview and open a PDF;
