Worth the money! The software is very easy to use from a smartphone or computer. Most people don't own a fax machine, so this feature is very handy! The subscription is necessary, but now with many places of business using editable PDFs, it's not needed as often as I'd like.

To start, drop your PDF file or upload it from your device or your cloud storage service. Select the elements to flatten: annotations, form fields, and/or layers. Click on the Flatten button. Download the flattened PDF file to your computer or save it directly to your cloud storage service.
Flattening a PDF is necessary to reduce a document's size, if a PDF includes a form, or to meet other sponsor formatting requirements. PDFs that are not flattened can create errors when users upload documents to a sponsor's system.
Open the copy and choose Advanced > PDF Optimizer. Click the Clean Up tab. Select Remove Hidden Layers Content and Flatten Layers, and then click OK. When prompted, save the Optimized PDF with another new name.
