Flatten a PDF – 3 Workable Methods to Render PDF Layers for Printing
Last Updated on September 21, 2025 by Tina Clark
Flatten a PDF is a feature of Adobe to convert PDF with multiple layers to a printable PDF that any printer can read. Similar to Photoshop, both Adobe InDesign and Adobe Acrobat enable you to combine all layers, including the color profile, interactive form, and embedded fonts. If you just send a PDF to another computer without the fonts you used or have an interactive form with specific data filled in, the fonts will not be available or replaced with one used in the computer. It is the reason that you have to flatten a PDF for printing or sharing.

Besides Adobe products, PDFelement is one of the best PDF editors with the flatten PDF feature. Whether you need to combine multiple layers for the fonts or adjust the different parameters for printing, there are advanced features to achieve the optimal effect. Moreover, it also provides multiple editing functions and toolkits to polish the PDFs.
1. Flatten PDFs and combine multiple layers without installing Adobe products.
2. Preserve the original frames, fonts, color profiles, tables, pictures, links, etc.
3. Fill and sign PDF forms, convert non-interactive forms to editable content.
4. Adjust different settings, such as gray-scale and double sides for printing.
Step 1: After you have downloaded PDFelement on your computer, you can install it. Launch the program and open the PDF file by clicking the Open files button on the home page. Usually, you can find the fonts available and view the PDF directly with the program.
Step 2: Click the Flatten File button under the Tool menu. It will combine the PDF layers and save a flattened PDF for printing or sharing. Once you have flattened the PDF, the program will generate a new file named XXX_Flatten to distinguish it from the original one.
Step 3: To print the flattened PDF, you can adjust the fonts, fill in the form, and optimize the PDF beforehand. After that, you can click the Print button from the File menu. Adjust the print settings, page size, form, comment, and others before clicking the Print button.
