Annotate PDF
Annotate a PDF in your browser — highlight, draw, add arrows, shapes, text, notes and signatures. No upload, no signup.
Mark up a PDF without sending it anywhere: highlight text, draw freehand, add rectangles, lines, arrows, sticky notes, signatures and images. Move, resize and recolor every mark, then download the annotated file. Works for reviewing contracts, grading assignments, or leaving feedback on a draft — all in the browser, so the document never leaves your device. Free, no signup, no watermark.
