Text markup comes to the editor
Highlight, underline, strike, and squiggle real text, plus notes, callouts, and an eraser, all in your browser.
Edit PDF’s Edit-text mode just grew a full markup toolbar. Drag across any text in your document and the highlight snaps to the exact words you selected, the way it does in a desktop PDF app: multi-line selections wrap cleanly, double-click grabs a word, and the live selection tint previews the color you’re about to commit.
Highlighting is only the start. Underline, strikethrough, and squiggly underline use the same text-anchored selection. Proofreading marks cover the editing workflow: an insert caret you click between words, and a replace mark that strikes the old wording and opens a comment bubble for the new. There’s a translucent highlighter pen for freehand emphasis, sticky notes, callouts with leader arrows, and an eraser that scrubs any of it away.
Like every FernPDF tool, the whole thing runs in your browser. The text layer that powers selection is built locally from your document, the markup is drawn locally, and saving bakes it into a copy on your device. Open the network tab while you work: no upload, ever.
One detail we’re proud of: comments don’t flatten into pixels. Sticky notes and proofreading remarks are written into the saved file as standard PDF annotations, so they pop open in Acrobat, Preview, or any other reader your reviewer happens to use.
Try it yourself. Every FernPDF tool runs in your browser. Open one and watch the network tab.
