Just like its name suggests, JPEG2PDF PRO is an app that's all about one thing: converting JPEGs to PDFs. A better name for the app (even though it would have been just as generic as the current one) would be Image to PDF, as JPEG2PDF PRO supports many more formats.

To be more precise, it supports JPG, PNG, PNG, BMP, SVG, TIFF, and many more. What's more, the app can encrypt PDF files with AES-256 bit, one of the strongest levels of encryption.

One of the best aspects of this app is that it provides a lot of options when it comes to converting images to PDF. To start off, the app allows you to convert images individually and in bulk.

The app has something called auto-orientation, auto-page numbering (with support for various fonts), and auto-page formatting, however, there's a lot you can change to achieve exactly what you need.

The app supports the standard PDF page sizes (A4, A3, A5, letter, and so forth), as well as greyscale, black, and white images in PDF. You can also manually set the DPI values for the images, add encryption to your PDFs, as well as tweak the page margin (as well as the image position within the page).

Despite the fact that there's nothing really spectacular about this app, it gets the job done. The whole experience is a pleasant one, even though there are a lot of GUI elements, as well as various menus (such as the Advanced Page Settings and App Settings.

When it comes to looks, the app is not all that Linux-like. It looks more like an app designed for Windows, but that shouldn't be a deal-breaker. JPEG2PDF PRO is an efficient app that's worth having around if you want to convert lots of images into PDFs with ease.
