What is PDF Editor?

The PDF Editor is a free online tool to annotate, mark up, and enhance your PDF documents. Add text annotations, freehand drawings (perfect for signatures), rectangles, circles, highlights, and images. Choose colors and sizes for each tool. All changes are saved directly into the PDF file. Processing happens entirely in your browser — your documents remain private.

How to edit a PDF?

Upload your PDF file. Select a tool from the toolbar: Text to add text anywhere, Draw for freehand lines and signatures, Rectangle/Circle for shapes, Highlight for semi-transparent overlays, or Image to place a picture. Choose a color and size. Click or drag on the page to add annotations. Use Undo to remove the last annotation, or Clear to remove all. Navigate between pages. When done, click Save to download your annotated PDF.
