How to: Convert Several Images into a Single PDF Using Preview

 

By Tim Hardwick of MacRumors

Over the years, Adobe’s PDF file type has become a universally accepted method for sharing digital documents. The format’s cross-platform adoption means the documents can be viewed on almost any mobile device or computer, so it’s no surprise to find that macOS includes native support for viewing and creating PDF files.

In the Preview app, for example, it’s possible to create a single multi-page PDF document out of several separate image files. The feature is particularly useful if you need to share a number of scanned documents over email or digitize something for reference. Keep reading to learn how it’s done.

HOW TO CONVERT SEVERAL IMAGES INTO A SINGLE PDF

In Finder, select all the images you want to include in the PDF. To do this, drag a box over several images files using your mouse cursor, or select them individually by holding the Command key and clicking them one by one.

Right-click (or Ctrl-click) one of the highlighted files and select Open With -> Preview in the contextual dropdown menu.

 

In Preview’s sidebar, drag the thumbnail images into the order that you want them to appear in the PDF document. Use the Rotate button in Preview’s toolbar to change the orientation of individual pages (drag a selection over multiple pages to rotate several at once).

In the Preview menu bar, select File -> Print…, or use the Command+P keyboard shortcut to bring up the Print dialog.

Click Show Details to expand the Print dialog and browse the full set of options. Make sure the All button is selected in the Pages options. Note that you can double-check the orientation of each image by clicking the arrows below the print preview, and use the Orientation buttons to correct any if required.

Select Save as PDF from the PDF dropdown menu in the lower left of the Print dialog.

The Save dialog will appear. Give your new PDF a name and choose a save location. Fill in the Title, Author, Subject, and Keywords fields if desired (these details are searchable in Spotlight). The Security Options… button also lets you optionally set a password to open the document, copy from it, and/or print it.

Click Save when you’re done.

Note that the Save as PDF option can be accessed from the Print dialog window within a number of macOS apps, not just Preview. You can use it to create PDFs of web pages viewed in Safari, or Word documents opened in Pages, for example.

App of the Week – Adobe launches free document scanning app for Android and iOS

 

By Blair Hanley Frank of VentureBeat.com

Adobe is getting into the mobile scanning game with a new free iOS and Android app aimed at providing users with high-quality images of physical content they want to capture digitally.

It’s called Adobe Scan, and it works similarly to a bunch of other apps already available. Users point their smartphone cameras at whatever document, white board, or presentation screen they want to capture, and the app automatically crops the image to just pick out a document.

The clearest difference between Scan and other apps, like Microsoft Lens, is that the app integrates with Adobe Document Cloud and automatically performs optical character recognition on the PDFs it generates. Users can then copy and paste text from those documents into other files.

But Adobe also put in a lot of work on building machine intelligence into Scan from the ground up, according to Akhil Chugh, a senior product manager for Document Cloud. The app uses a variety of machine learning and image processing algorithms to help deal with the myriad issues that arise with mobile scanning, like trying to differentiate a document from a similarly colored background and figuring out which areas of a document warrant optical character recognition.

“Our goal has been to create a digital document that’s as good as you would get from a flatbed scanner, or as good as the real document,” Chugh said.

Specifically, Adobe is using genetic algorithms (so named because they’re generated by simulating natural selection) to handle document boundary detection. For differentiating text from images, Adobe is using tree- and logistic regression-based classifiers. Those machine learning tools are a part of Sensei, Adobe’s name for its internal ML framework and features.

Adobe is counting on its document expertise and machine learning capabilities to boost Scan in a crowded market. The app is free for people to use, but it requires the creation of a Document Cloud account. Scanned files are stored in Document Cloud automatically but can also be saved to other services.

While it’s possible for Scan to capture images without a network connection, all of the OCR work is handled in Adobe’s cloud. That means text recognition requires sending images of the document over the internet, which may not be an appealing option for some sensitive content.

The launch of Scan is a significant milestone, but Adobe plans to further refine the app over time as part of its Document Cloud portfolio. The company has invested a great deal in handwriting and font recognition, for example, so it’s possible features like that could show up in Scan going forward.

On the machine learning front, the team is investigating how to best implement deep learning in Scan and across Document Cloud. It’s also looking into using generative adversarial networks, which are designed to help create content.
