PDF Note Taker & Annotator – Margin Notes, Highlight

Description

Take notes beside any PDF. Widen the left or right margin, then handwrite, highlight, type and draw — all saved into the PDF. Write your notes NEXT TO the text, not on top of it. Every other PDF annotator makes you scribble over the document, cramming notes into whatever white space happens to be left. PDF Note Taker does something no other extension does: it widens the page itself. Add a margin to the left, the right, or both — and that blank space becomes a real part of the page, with room to actually think. Then handwrite, highlight, type, draw arrows and drop in images. When you're done, everything is saved back into the PDF file itself — not a proprietary sidecar. Open it in Preview, Acrobat, or on your phone, and your notes are simply part of the document. ★ CORNELL NOTES ON ANY PDF Because margins are independent on each side, you can build a proper Cornell layout on any document: a narrow cue column on the left for questions and keywords, the original page in the middle, and a wide notes column on the right. No printing. No templates. No copying the reading into a separate notebook — the source and your thinking finally live on the same page. ★ WHAT YOU CAN DO • Widen either margin — The headline feature. Add blank space to the left, right or both sides of any page, one page at a time. It becomes genuine page geometry in the exported file. • Handwrite naturally — Pressure-sensitive inking for stylus and tablet users, with smooth, tapered strokes. Works with a mouse or trackpad too. • Highlight real text — Select text the way you normally would and it becomes a clean, per-line highlight. The words stay perfectly readable underneath. • Type formatted notes — Click anywhere and start typing. Resize the text box and text reflows; bold any word with Ctrl+B; change size and colour. Notes export as real, selectable, searchable PDF text — not flattened images. • Point with arrows — Drag an arrow to call out anything on the page. Perfect for tying a margin note to the exact line it refers to. • Box anything — Draw a hollow rectangle around a formula, diagram or clause. The middle stays transparent, so whatever you box is still fully readable. • Add images — Insert screenshots, diagrams or photos from a file picker, by drag-and-drop, or with a simple paste. Move and resize them freely. • Draw on top of images — Images sit on the lowest layer, so you can ink and annotate directly over any screenshot or diagram you add. • Erase and undo — Remove individual strokes, arrows and highlights, with full undo support. • Jump to any page — Type a page number in the toolbar and go straight there. • Save into the same file — Saving writes back to the file you opened, so you don't collect a folder of "document-annotated-final-v2.pdf" copies. ★ BUILT FOR Students annotating lecture slides and textbooks. Researchers marking up papers. Lawyers and editors reviewing contracts and drafts. Engineers redlining specs and drawings. Anyone who has ever printed a PDF just to scribble in the margins. ★ PRIVATE BY DESIGN — YOUR FILES NEVER LEAVE YOUR COMPUTER There is no account, no sign-up and no server. Your PDFs are never uploaded anywhere. Every page is rendered, annotated and saved entirely inside your browser, and your notes are stored in local browser storage on your own machine. The extension has no analytics and no tracking of any kind. ★ HOW IT WORKS 1. Open any PDF — click a PDF link, open a local file, or use the toolbar's Open button. 2. Hover a page and press + on the left or right edge to open up margin space. 3. Pick a tool — pen, arrow, box, highlighter, text or eraser. 4. Press Save. Your annotations are baked into the PDF permanently. A short guided tour walks you through it the first time you open the extension. ★ GOOD TO KNOW • Works with online PDFs and, once you enable "Allow access to file URLs" on the extension's details page, with local files too. • Handles real-world documents: scanned pages, JPEG 2000 images, rotated pages, and PDFs whose crop area differs from the page size. • Saved files are flattened into the page content, exactly like printing to PDF — so they open identically in every reader. • Typed notes export using the standard PDF font, which covers Latin characters.
