Why should we flatten and secure our resources?
⭐️ The Terms of Use of most clipart artists require that our resources are flattened and secured as a PDF file.
⭐️If your resource is saved as a PDF file, but not flattened, anyone could lift the images and copy your content easily.
I use Flatpack from @bearwoodlabs to flatten my resources. It’s one of the best investments I have made in my business. I used to save my resources as JPEG and then insert each of the images, one at a time, on my pages. It worked, but it took a lot of time. Flatpack solved that problem. It does it in a few seconds. I no longer have to convert my resources into JPEG to flatten them.
Once flattened, I save them as PDF files using Adobe Acrobat Pro, which is also one of my best purchases. Once saved, I add a password that will be needed to edit them.

In the comments section below, please share what programs you use to flatten and save your files.
