How to edit a PDF (add text, highlights and shapes) on Mac
You don't need special software to edit a PDF (add text, highlights and shapes) on Mac. FernPDF runs entirely in Safari or Chrome on macOS: open the tool, drop your file, download the result. The whole editor runs in your browser: rendering, editing and saving all happen on your device.
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 edited PDF 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.
Step by step
- 1Open the Edit PDF tool in Safari or Chrome on macOS. No install, no account.
- 2Add the PDF you want to change: drag it straight into the drop zone from Finder, or click to open Safari's or Chrome's native file picker.
- 3Add text boxes, highlights, shapes, images or whiteout, or switch to Edit text mode to rewrite existing lines.
