Hello there, does anyone know how to straighten out scanned documents in pdf format using Preview that was accidentally not aligned during scanning? Most preferably without using an Adobe program. Hope someone can answer this soon. Thank you ! 🙂
MacBook Pro with Retina display, OS X Mavericks (10.9.1)
Here's a solution if you don't have many pages to straighten. It works but it takes a few steps:
[1] First export from in Preview from PDF to TIFF, set the resolution to at least 200 pixels/inch.
[2] Then import into Photo. After importing the image into iPhoto, then straighten the image.
[3] Then export the photo back to PDF. If you do multiple pages, then you can join them back together as one PDF in Preview.
This works, but it takes a few steps. It'd be nice if Apple would add the "straighten" feature to Preview. :-)
I don't know how to fix an existing scan, but I do know the Fujitsu Scansnap scanners do it automatically on scanning. I bought one of them last year for some work even though I had an existing scanner. If you do a lot of scanning it's worth considering.
Hi & thanks for the suggestion. 🙂 However I have a reasonable good scanner from Canon & also I know that the scanner I have can do that too with its scanning software that comes with it.
Its just that I thought prehaps if I was in the situation where I didnt have that software on my computer and if I didn't have Adobe Acrobat, and I only have Preview on my Mac. Would I still be able to do the straightening that I mentioned?
Note: for some reason the help on Preview can't seem to connect to the internet right now on my Mac.
Preview is just a viewer, so I don't think so.
If that's the case, can you or anyone suggest a free software that could do this? Thanks! 🙂
This isn't free, but it does what you're after. I haven't tried that particular feature, but I have used the software and it's good.
