How to Convert JPG to PDF on a Mac
macOS can do this with Preview — and it's good. The browser tool below wins when the page order matters or when you're combining many images.
Add JPG, PNG, HEIC or WebP images
Each image becomes one PDF page, in the order shown
or drag and drop files here
The browser way (order under control)
- Drag your JPG, PNG or WebP files from Finder into the drop zone above.
- Check the numbered list — that's your exact page order; fix it with the arrows.
- Pick Same as image, A4 or US Letter, then click Create PDF.
Built and tested on macOS in Chrome, Firefox and the Safari engine. Images are embedded without recompression, and nothing leaves your Mac.
The built-in way: Preview
- Select the images in Finder and open them together (they land in one Preview window).
- Show thumbnails (View → Thumbnails) and drag them into order in the sidebar.
- Select all thumbnails, then File → Print → PDF dropdown → Save as PDF.
Two quirks to know. File → Export as PDF exports only the selected image, not all of them — the multi-image path goes through the Print dialog, which surprises everyone the first time. And the Print route forces a paper size, so photos get white margins unless you fiddle with scale. HEIC photos from an iPhone open fine in Preview — and in the tool above, because Safari on macOS decodes HEIC natively, so AirDropped iPhone photos need no conversion step either way.
Which to use
- Preview — a couple of images, when you already have the files open anyway.
- This page — many images, explicit ordering, HEIC straight from AirDrop, or pages that should keep the image's own size with no margins.
