Rotate View
This feature rotates all pages of the document but it only rotates the view of the document in the current session of acrobat (the rotation will revert back to its original orientation the next time you open the document). To save changes to a document's rotation, see Page Thumbnails.
To enter a tool, click the corresponding icon in the right pane (the Tools or Task pane). (If the right pane of the Acrobat interface isn't already expanded, then click the arrow on the right of the screen, or choose "View -> Show/Hide -> Tools Pane".) Or you can enter a tool by using the menu: "View -> Tools -> [tool] -> Open".
To exit a tool, click the Close button in the top right.
To add additional tools to the Tools pane, go to the Tools tab near the top left of the main acrobat window and click "Add" below the new tool.
To edit a PDF, click the "Edit PDF" button in the toolbar on the right. From there, there are several options on the toolbar in the top middle. A common one is to choose "Add Text" and place a text box on the page where you need it, and then enter some text.
I was trying to find a format to export the PDF to that would allow me to embed it in a google site and be able to search its text via google sites search bar, but didn't have much luck. I was testing with a PDF of an old newspaper (Frank Leslie's Illustrated Newspaper, August 30, 1862, page 1) that had three columns of text that sort of bled off the page. The only format that preserved the text within their columns was when I exported to a power point.
Image
To split a single or multi page pdf into separate jpg’s for each page (with automatic incrementing of file numbers, you just supply the base name), use the Image export option.
Use this tool to re-arrange the layout of pages, add/remove pages, rotate them, etc.
You can affect multiple pages by shift or control-clicking them, marque-selecting them, or pressing ctrl+a to select all pages. Tools on the toolbar such as rotate and delete work in conjunction with your current manual selection or the selection filters available in the drop-down list to the left of the rotation buttons.
To move a page to a different location in the page order, drag its thumbnail to the new location.
To add or insert a page, click "Insert" on the toolbar and then choose the appropriate menu item, such as "From File" to insert the pages of another PDF. Choose the page order in the popup.
To delete a page, mouse over the thumbnail for that page and click the trash icon.
To rotate a page, mouse over its thumbnail and click one of the rotation icons. For more advanced batch rotation features, see Page Thumbnails.
In the right pane, click Comment.
In the Comment toolbar at the top, click the drawing tool (pencil icon) to draw a freehand line.
By clicking the "Fill & Sign" button on the right toolbar, you have access to options such as adding a hand-drawn signature, adding check marks, etc.
(I think that the rotation buttons only affect the current page. For the most advanced batch rotation features, see Page Thumbnails.)
Recognize text
If the PDF is a scan of a book or other physical document that includes text, then you can convert the PDF so that you can search the text in the document rather than the text simply appearing as part of a photographic image.
Click the drop-down for "Recognize Text" and click "In This File".
Click the "Recognize Text" button. This converts each scanned page to a searchable image so that you can search for text. It might take quite some time to convert a long document.
When the conversion is complete, click Close and click "File -> Save".
(If the Print Production tool isn't listed in the Tools pane, then you can add it by clicking "Add" below its name in the Tools tab near the top left of the main acrobat window.)
Output Preview
In the Preview section of the Output Preview window, choose “Object Inspector”.
Click inside the image you want to inspect. The resolution of that image is displayed in the Output Preview window.
The navigation pane is on the left side of the main acrobat window. To expand it, click the arrow on the left side of the screen or choose "View -> Show/Hide -> Navigation Panes -> Show Navigation Pane".
Page Thumbnails
To expand the page thumbnails section, click on the "Page Thumbnails" button in the navigation pane.
This section can be used to quickly navigate to a specific page of the document. It provides quick access to many of the tool available in Organize Pages, such as the ability to insert, rotate, reorder, and delete pages.
Rotation
The rotation buttons in the Page Thumbnails section and the Organize Pages and Enhance Scans tools can be used to rotate pages and the document, but for the most advanced batch rotation features, click the Options button and choose "Rotate Pages". The popup provides many advanced options. For example, to flip all pages in the document right-side up for a document that was completely upside-down, choose 180 degrees for Direction, All for Page Range, Rotate Even and Odd Pages and Pages of Any Orientation.
Choose "File -> Save".
To expand the page bookmarks section, click on the "Bookmarks" button in the navigation pane.
To expand the attachments section, click on the "Attachments" button in the navigation pane.
zip compression is lossless, and jpg compression is lossy.
I think that technically, this would yield the highest quality file:
Create a word docx, and drag and drop the 300dpi 7-inch tiff from photoshop into the word docx.
Save the word file as a pdf (File -> Save As -> PDF).
Open the resulting pdf in Acrobat, and choose File -> Save As Other -> Optimized PDF.
In the PDF Optimizer window, click the "Images" section in the left pane.
For all three image types, choose Bicubic Downsampling to 300 ppi, and set the Compression to ZIP.
However, I visually couldn't tell the difference between the result of the process above and simply saving a High Print Quality Adobe PDF directly from Word, so I would just go with this process, which is simpler and creates a smaller file:
Create a word doc, and drag and drop the 300dpi 7-inch tiff from photoshop into the word doc.
In Word, save the file by choosing File -> Print. Then, instead of clicking the Print button in the Print window, click on the drop-down list in the bottom left corner of the Print window and choose "Save as Adobe PDF".
In the popup, choose these settings and click Continue:
Adobe PDF Settings: High Quality Print
After PDF Creation: Launch nothing
Save the file.
If parts of the page are obscured (blurred, etc) but they were clear before, then try clicking on the obscured part and then clicking off of it.
I had a problem where I made edits to a pdf but then couldn't save it. I got this error message:
The pdf I was editing was in a shared folder in Google Drive. I suspect that the sharing prevented me from saving changes to it, so I made a copy on my desktop. I seem to be able to save that copy so far...
