PDF document is easy to integrate with different contents in a fixed-layout which makes it a commonly-used format. There are times that we just leave a PDF unsaved or delete the PDF files for mistake, then need to recover them back.
But how to recover an unsaved or deleted, even corrupted PDF file on Mac? Is it possible to do so? Here we will give the complete guide to do Mac PDF recovery easily and successfully.
Yes, of course.
PDF files can be lost due to many reasons including unintentionally deleting, emptying the Trash, formatting hard drive, partition loss, corrupted operating system, infection of virus, etc. But it is still possible to recover.
When you delete a PDF file on your Mac, your Mac does not actually erase the actual data of the file. Instead, it just quickly changes the corresponding record in the file system to mark the PDF file as “deleted”. And the space of your deleted PDF file is available for use. When the system needs space to write another file, it may claim that space and store a different file in it. This is the point at which the actual data is lost.
So before your deleted or lost PDF files are overwritten by new files, they can be recovered. That’s why you should stop using your Mac when you find you PDF file missing or deleted by mistake.
