How do I flatten a PDF before printing?

You can use the built-in "Print to PDF" trick on your computer, or you can use a program like SwifDoo PDF. Doing this locks all your typed words in place so the paper prints out perfectly.

What does it actually mean to flatten a PDF?

It means turning a document with clickable, typing boxes into a flat, normal picture. Once it is flattened, no one can click or type in the boxes anymore.

Can I unflatten a PDF later?

Usually, no. Once a document is flattened, the text becomes a permanent part of the page. It is always a good idea to save a copy of the original filled form just in case you need to make changes later.

2. Flatten Form Fields in PDF with Online Tool

Sometimes you might be in a hurry. You might be using a public computer or a device where you cannot install new software. In this case, you can use a website to do the work for you. Smallpdf is a very popular website that lets you flatten a PDF online without downloading anything.

Open your web browser and go to the Smallpdf website. Look for their tool designed to edit or flatten PDFs.

Look for the small printer icon on the screen and click it. You can also press Ctrl and P on your keyboard at the same time (or Cmd and P if you use a Mac).

A print menu will pop up. Look for the box that shows the name of your real home printer. Click that box and change it to "Save as PDF" or "Microsoft Print to PDF".

Click the Save or Print button at the bottom. Your computer will ask you where you want to save the new file. Choose a folder, and you are done!
