You can also save individual PDFs to other file formats, including text, XML, HTML, and Microsoft Word. Saving a PDF in text format allows you to use the content with a screen reader, screen magnifier, or other assistive technology.
If you don’t have access to the source files that created an Adobe PDF, you can still copy images and text from the PDF to use elsewhere. You can also export the PDF to a reusable format, or export images in a PDF to another format.
Adobe Acrobat Reader users can save a copy of a PDF or PDF Portfolio if the creator of the document has enabled usage rights. If a document has additional or restricted usage rights, the document message bar under the toolbar area describes the assigned restrictions or privileges.
