How to turn JPG or PNG images into a PDF on Mac
You don't need special software to turn JPG or PNG images into a PDF on Mac. FernPDF runs entirely in Safari or Chrome on macOS: open the tool, drop your file, download the result. Photos of IDs, receipts and forms stay on your device, the safest way to PDF anything personal.
On Mac, you drag it straight into the drop zone from Finder, or click to open Safari's or Chrome's native file picker. Once the document is ready, it downloads to your Downloads folder in Finder, the same place Safari and Chrome always save to, Command-Option-L (Safari) or the downloads tray (Chrome) gets you there fast.
Gatekeeper never gets involved, because nothing is installed: no unidentified-developer warning to click through, no .dmg to mount, no permission prompt to grant.
There's nothing to install: no Preview workarounds, no App Store downloads, no Rosetta questions. If your Mac runs a modern browser, it runs FernPDF, on Apple Silicon or Intel.
