A free program for Android, by Rectfy.

The app is designed to convert your images to PDF files in a quick and easy way.

Conversion Process:

The first thing you need to do is select the images you want to convert to PDF files. This can be done by dragging them from your device’s main screen or by using the built-in camera. Next, select the desired output format. There are a lot of formats available, and you can choose one of them. You can choose to convert all the images in the current folder or select individual images to convert.

The last thing you need to do is click the “Convert” button. The app will then start the conversion process. The app will automatically convert your images and save the resulting PDF file in the folder you have selected.
