How do I combine images into a PDF?

Upload your images, arrange them in the correct order, and the tool creates a single PDF with each image on a separate page ready to download.

What image formats can I upload?

Common formats such as JPG and PNG are supported for combining into a single PDF document.

Will image quality be affected when converted to PDF?

The conversion aims to preserve the original image resolution. Very high resolution images may be scaled to fit a standard page size, which can affect the pixel density of the output.

Can I use this to combine multiple scanned photos into one document?

Yes. This is a common workflow — scanning or photographing multiple pages and combining them into a single PDF for easy sharing, archiving, or emailing.
