This free browser PDF Editor covers the PDF tasks people run into most often — merging multiple PDFs into one, extracting or splitting out specific pages, adding a watermark, and stamping page numbers — plus a set of annotation tools for marking up a document directly: freehand drawing, text boxes, rectangles, highlights, and placing images onto a page.
Every one of those operations happens locally in your browser rather than on a remote server, which matters a lot for PDFs — contracts, IDs, financial statements, and other documents people specifically don't want passing through a third-party upload. The toolbar-driven interface keeps each function (select/move, text, draw, rectangle, highlight, image) one click away, so switching between reviewing a document and marking it up doesn't require jumping between separate tools.
How to Use PDF Editor
- Drop a PDF onto the upload area or click to browse; it's processed entirely in your browser.
- Use the top toolbar for page operations — New PDF, Merge PDF, Blank Page, Duplicate, Extract, Split Here — and click thumbnails in the sidebar to select pages.
- Open the Watermark or Page Nos. modal to add a text watermark or automatic page numbers (position, size, color, opacity), then Apply or Remove.
- Switch to an annotation tool (Text, Draw, Rect, Highlight, Image) in the second toolbar, set its color/size options, and click or drag on the page to place it.
- Zoom with the +/− buttons, use Undo to reverse changes, then click Download to save the finished PDF.
