Turn a set of images into one PDF in reading order, so everything lands in a single file you can submit, email, or keep together.
Rename the images first (page-01, page-02…) so any upload order sorts itself into reading order.
Every phone makes image sequences easy: photos of a document, a scanned chapter, a stack of pages shot with the camera. The hard part is that ten images stay ten files, and submissions want one. Converting them into a single PDF is the fix.
Reading order is the one decision
A JPG-to-PDF converter places images in the order they appear in the list. If you shoot ten pages, the order of the result depends on the order you select them — not the order your phone happened to save them.
Easiest habit: rename before converting (page-01.jpg, page-02.jpg…). Then any upload order sorts itself, and the PDF lands in reading order.
When this is the right move
It's right whenever several images have one job: a single form upload, one email attachment, one file to keep on your phone. It's also the last step in a scanner workflow — grab the images, merge them, done.
Step by step
The whole job, in order:
- Name your images in reading order first, to remove the guesswork.
- Open the GainUtility JPG to PDF tool and add the images.
- Drag to reorder the list so it matches how the document should read.
- Export the PDF and open it once to confirm the page order.
- Combine the result with other PDFs using the merger if you need one larger document.
