An easy-to-use app to convert multiple JPG files to one PDF file offline.
Get from Google Play

PDF files can only be saved in the app-specific folder and "Download" folder on Android 11 or newer. Therefore the default output folder is changed from "/PDF/" to "/Download/PDF/".

JPG to PDF Converter is an easy-to-use app to convert multiple JPG files to one PDF file offline.

First, you choose JPG, PNG, WEBP, HEIC or AVIF images on your Android phone, select a preset PDF page size or enter page width and height, set PDF page orientation, then tap the "Convert to PDF" button to start conversion. JPG to PDF Converter uses multithreading to improve conversion speed. It only takes a few seconds to convert hundreds of image files.

Additionally, we provide free online conversion services to convert JPG to PDF or convert PDF back to JPG.

Notice: The conversion results in the app (source codes are written in JAVA) are different from conversion results in our software (source codes are written in Delphi) or online service (source codes are written in C++).
