PDF Markup
Mark up a PDF in your browser
Add text, draw on the page, leave comments, stamp it approved, apply a watermark or number the pages — all without installing anything or handing your document to a server.
Open PDF Content →Write on the document
Text & Drawing lets you place typed text anywhere on a page or draw freehand over it. Useful for filling in a form that was never set up as a fillable PDF, correcting a figure, or sketching a change on a layout.
Annotate adds review markup — highlights, notes and comments — so you can send feedback back on a document without rewriting it or printing it out.
Label and brand the file
Stamp applies a mark such as Approved, Draft or Confidential. Watermark lays text across the page, either diagonally or tiled, which is the usual way of marking a document as a preview, a draft, or not for distribution.
Page numbers adds sequential numbering with control over position and starting value — worth doing before a document goes to print or into a formal submission where page references matter.
Nothing leaves your computer
Marked-up documents are often the sensitive ones — a contract under negotiation, a drawing with client comments, a draft nobody outside the room should see.
Every change here happens inside your browser. The file you open is read locally, edited locally and saved back to your own machine. There is no upload step, no copy on a server and no account to create.
