How to Annotate a PDF Online

Creatorr's PDF annotator lets you mark up any PDF with drawings, highlights, text boxes, arrows, and rectangles — all from your browser with no software to install.

Available Annotation Tools

  • Pen — Freehand drawing. Adjustable color and line width.
  • Highlight — Semi-transparent highlight marker for emphasizing text.
  • Rectangle — Draw attention boxes around important areas.
  • Arrow — Point to specific elements on the page.
  • Text — Click on the page to add typed annotations.
  • Undo / Redo — Step back and forth through annotation history.

Steps

  1. Upload your PDF file.
  2. Select an annotation tool from the toolbar.
  3. Draw or click on the PDF page to annotate.
  4. Navigate pages with Prev/Next buttons.
  5. Click "Download PDF" to save with annotations embedded.

Privacy

All processing is client-side. pdf.js renders pages, Fabric.js handles annotations, and pdf-lib embeds them into the saved PDF. Nothing is uploaded.
