Fast PDF Converter is a free Android app developed by Sparksoft solutions that allows users to create and edit PDF files from images. With this app, you can choose images from your gallery and arrange them in the desired order to create a PDF document with just a single button press. The images in the PDF file are not transformed and are placed as they are, so the final size of the PDF file is approximately equal to the sum of the sizes of the images.

One of the standout features of Fast PDF Converter is its speed. The PDF file generation rate depends on the parameters of your Android device, as well as the size and number of images. However, on average, a smartphone can create a document from 10 images of 4 MB each in less than 11 seconds. The app does not require an internet connection, so you can use it anywhere, anytime.

Fast PDF Converter also allows you to break PDF files into images and save them in their original size and format. The app uses a number of support libraries such as Card Library, Picasso, Material Dialogs, Hawcons, and Core Java Library + PDF / A, xtra and XML Worker, among others. However, the application is not yet sufficiently tested, so errors and exceptions may appear, which will be removed in future versions.
