Nothing leaves your device
The browser tab opens and rewrites the PDF itself. There is no upload, no processing queue and no server copy you would have to ask someone to delete later.
Highlight, underline, strike through, add notes, and draw on any PDF.
Drop a PDF here, or choose one from your device. Highlight, underline, strike through, add notes, and draw by hand — everything runs in this browser tab.
Tap a mark to move, resize, or delete it.
The annotation editor puts highlighter, underline, strikethrough, text notes, freehand ink and shapes on one canvas. Text marks snap to the real text layer, so a highlighted sentence sits where it should. Marks are drawn into the page itself rather than saved as PDF comments. It all runs in the browser tab, and the file never leaves your device.
The browser tab opens and rewrites the PDF itself. There is no upload, no processing queue and no server copy you would have to ask someone to delete later.
Select, highlight, underline, strike, note, draw, rectangle, ellipse, line, arrow, eraser — with swatches or a custom colour, and the fill, opacity, thickness or text size a tool uses.
Drag across a sentence and the mark aligns to the real text layer. If a page has no text layer, the editor says so and the mark follows your drag instead.
Drop the file onto the editor or pick it from your device. It renders straight away, with a page rail, zoom and full screen, and no account to create.
Pick a tool, set colour and thickness, then drag on the page. Undo, redo, duplicate, reorder and erase are all there, plus apply a mark to every page.
Export when the markup is done, with no watermark. The marks go into the page content, not into PDF comment objects, so every reader sees the same thing.
While the file is open in the editor, yes: undo, redo, delete, duplicate and clear all are all there. After export the marks are part of the page content, not PDF annotation objects, so they never show up in another reader's comment list and cannot be edited there. Keep the original.
Highlight, underline and strike look for a real text layer. Scanned or image-only pages have none, so the editor tells you and draws the mark along your drag instead. It lands where you dragged, just not letter-perfect. Extract PDF Text
Note text is written with the standard Helvetica font, which only covers Latin characters. Chinese, Japanese, Korean, Arabic and Cyrillic will not render as you typed them, so use a drawn mark for those documents.
Yes. Undo and redo cover every mark you place while the file is open, and a selected shape can be deleted, duplicated, brought to front or sent to back. Clear all empties the markup in one step.
Apply to all pages copies the selected mark to the whole document at the same position, which suits a stamp, a review box or a signature line. Place it once, check one page, then apply it.
You can draw your signature with the freehand ink tool and it stays exactly where you put it. It is a visual mark, not a certificate-based digital signature, so treat it the way you would a pen signature on a scan. Fill and Sign PDF
Nowhere. Reading, drawing and export all happen in this tab, so the document stays on your machine and no file size limit applies. The site itself does load analytics scripts, as most sites do.
