Additionally, you must upload a flattened PDF file to comply with some publishers’ requirements. Finally, if your PDF has several layers, you may need to flatten it to print how you want. If you want to make a flattened PDF, you will need a specialized PDF editor to create it.
What Happens When a PDF is Flattened?
A document becomes safe and secure when you flatten it. The document will become secure, and it will be impossible for the user or recipient to make changes. Flattened PDF files prevent modification of files so that changes cannot be made, unlike ordinary PDF files or scanned documents.
A fillable PDF offers users many interesting interactions. Some of them are checkboxes, text boxes, radio buttons, drop-down menus, and lengthy boxes for changing values. When you flatten a PDF, modifications can no longer be carried out on the layers of a document. Also, when you flatten a document, annotations are converted to native texts, removing transparency effects. Finally, when you flatten a PDF, additional elements, images, and header styles are merged into a single layer to reduce the file size.
