- Conversion Engine
- Choose a conversion engine to perform conversion.
- Same Conversion Engine Used in Our APP: Use the same conversion engine that our JPG to PDF Converter app for Android uses. The output PDF file's file size is optimized.
- Exclusive Conversion Engine: Use our exclusive conversion engine designed for only this website. It supports more image formats such as animated GIF or multi-page TIFF etc. The output PDF file's file size is not optimized.
- Open-source Conversion Engine: Use the best open-source conversion engine we have found online. It simply adds images to PDF without any optimizing or shrinking. The image in output PDF is exactly the same image before conversion.
- PDF Page Size
- Use image size as PDF page size by default. You can choose preset page size such as A4 Portrait/Landscape or choose "Custom Size" and enter page width and height. The image size will be resized to PDF page size if "Stretch image to fill page" is checked.
- PDF Compression
- Check "Enable PDF compression" to enable compression. Set JPG quality from 1 to 100. 1 meaning compress for small size, 100 meaning compress for max quality. Some formats, like PNG which is lossless, will ignore the quality setting.

- Added conversion engine that our JPG to PDF Converter app for Android uses. We have translated all JAVA codes for app to C# codes for website. Due to the differences between JAVA and C# languages, the conversion results may differ. You can also use this conversion engine to convert JPG to Word online.
- Added an open-source conversion engine for you to choose.
- Added support for 100+ other image formats such as SVG, HEIC, WEBP or JXR etc. These image formats will be automatically converted to JPG format after uploading.
- Increased maximum PDF page size to 14400 by 14400 units (200 by 200 inches). However the maximum page size will start to decrease when file number starts to increase. For example: the maximum PDF page size will be 5328 by 5328 units when there are 5 image files. This is a compromised method to prevent OOM (Out Of Memory) error on server.
- Use quick conversion algorithm if there is only one image file.
- Use image's actual width and height regardless of image resolution (pixels per inch).
- Removed PDF PPI setting which is confusing to most people.
- Added "Stretch image to fill page" option to remove white border.
- Reduced output PDF file size.
