When you have several images that belong together — pages of a scanned document, a set of receipts, or photos for an application — turning them into one ordered PDF keeps everything tidy.
Order matters
Add the images and arrange them in reading order before exporting. The sequence you set becomes the page order.
One file is easier to share
A single PDF is far easier to email or upload than a dozen loose image files, and most portals prefer it.
Step by step
- Rename your images so they sort in the order you want (01, 02, 03 rather than 1, 2, 3).
- Add them all to JPG to PDF at once and confirm the thumbnail order.
- Choose fit-to-image unless the result is going to be printed.
- Export, then compress if the file is heading for an upload form.
What usually goes wrong
Alphabetical is not chronological
IMG_9 sorts after IMG_10 on most systems. Zero-pad the numbers or drag the thumbnails manually.
Phone photos make enormous PDFs
Twenty images at 4 MB each is an 80 MB document. Compress after combining, not before.
Mixed orientations look untidy
Portrait and landscape shots in one file means the reader rotates their head every other page. Rotate first if it matters.
Frequently asked questions
Can I mix JPG and PNG in one PDF?
Yes — a good image-to-PDF tool accepts both formats together.
How do I control the page order?
The order of the thumbnails is the order of the pages. Sort by filename first, then drag anything that is out of place.
Can I mix JPG and PNG in one PDF?
Yes. Both are embedded the same way and end up as ordinary pages.
