Preview User Guide
Creating App Previews with iMovie You can easily create an app preview to showcase your app using iMovie. Start by capturing screen recordings from your iOS device or Apple TV with QuickTime Player on your Mac. Next, you’ll use iMovie to edit the recordings and add titles, transitions, a. From documents, resumes to books, PDF is a pretty standard file format. Mac’s default PDF viewer is Preview. But you can easily change the default PDF viewer on Mac in just a few clicks. Preview is great for viewing PDFs and basic annotating. However, it lacks a few features.
Preview automatically saves changes for you as you work, so you don’t have to save your changes manually. You can save a document manually if you want to, for example, save a copy of the document in a different location.
Preview periodically saves “snapshots” of your document, called versions, so that you can view the document as it appeared in the past and revert to a previous version. When you’re actively editing a document, Preview saves a version at least every hour, and more often if you’re making significant changes. Preview also saves a version when you open a document, save or duplicate a document, lock or rename a document, or revert to a previous version.
Manually save a Preview document
In the Preview app on your Mac, open a PDF or image that you want to save.
Do any of the following:
To make sure you have a version of a document with all of your changes: Choose File > Save.
If you created a new document by choosing File > New from Clipboard and now you’re ready to name the document and place it in a particular location: Choose File > Save, enter a name, select a file format, then choose where you want to save it. When you create a document from the Clipboard, your changes are saved automatically as you edit. However, you must save it to give it a name and store it in a location.
To save the document using a different filename, location, or format: Press and hold the Option key and choose File > Save As.
If you have iCloud set up and iCloud Drive turned on, you can save your documents in the Preview folder in iCloud Drive by clicking the Where pop-up menu, choosing “Preview — iCloud,” then clicking Save. See Use iCloud Drive to store documents.
Tip: You can also hold the pointer over the document title and click the arrow to save the document or change its location.
Create a copy of a document
In the Preview app on your Mac, open a PDF or image that you want to copy.
Do any of the following:
To create a copy of a document to edit in Preview: Choose File > Duplicate. When you’re ready to save the document, choose File > Save, enter a name, select a file format, then choose where you want to save it.
To create a copy of a document so you can archive it or convert it to another format: Choose File > Export.
Revert to the last saved or opened version
In the Preview app on your Mac, open a PDF or image that you want to revert.
Choose File > Revert To > Previous Save [date, time].
If you edit the PDF or image, choose File > Revert To > Last Saved [date, time] or File > Revert To > Last Opened [date, time].
Mac Preview App For Windows

In the Preview app on your Mac, choose File > Revert To > Browse All Versions.
Click a gray tick mark along the timeline on the right to display various versions of your document.

To restore your document to the state of a particular version: Display that version, then click Restore.
To create a new untitled document that duplicates a particular version: Display the version, press and hold the Option key and click Restore a Copy.
To leave your document in its current state: Click Done.

Was going to start a new thread on this, but will just bump yours: annotations has been broken in Preview since the High Sierra update (the older thread here: Re: preview.app pdf annotation bug). Had hoped the 10.13.3 update would have a new preview build, but it seems we've been on 10.0 (944.4) for a while now, and previous versions in High Sierra had the same problem.
My own annoyance with this — in addition to note annotations vanishing — is that every time I open a previously annotated pdf (whether it is highlighted, underlined, etc.), Preview decides the file has just been edited. Since I work with a large number of pdf files with notes and annotations, date modified is a handy way of organizing. Yes, I can tell Preview to revert back to previously saved version ('are you sure?' yes I'm sure), but I then have to close the file very quickly before the app becomes convinced it has just edited it again. And yes, I can use a file property editor to manually change the date modified, but the next time I open the file to read, it will be re-'edited' again.
Oh, also, if you drag a page from one pdf into another pdf — one of Preview's wonderfully handy features over the last years —, the 'alien' page cannot be bookmarked. Try it! It often will bookmark one of the earlier pages in the document instead.

The work-around I've adopted is re-annotating and then print-saving as a new pdf, which fixes the annotations in stone, as it were (that is, they are no longer seen as annotations but permanent 'fixtures'). Then reinsert my bookmarks from scratch. Then edit file properties to 'real' modification date. Needless to say this is very time-consuming, laborious, and was entirely unnecessary before High Sierra.
