Frequently Asked Questions

This editor allows you to add new text layers over existing content, but cannot modify pre-existing text characters directly. For direct text editing, you would need a PDF text editor tool. However, you can:

  • Add text boxes anywhere on the page
  • Highlight, underline, or strike through existing text
  • Add comments and annotations
  • Redact sensitive information

No, all processing happens locally in your browser. We don't store, upload, or transmit your PDF files to any server. This means:

  • Your documents remain completely private
  • No file size limits beyond browser memory
  • Works offline after initial page load
  • No account or registration required

You can add various annotation types to your PDF:

  • Text annotations: Add comments, notes, callouts
  • Highlights: Mark text with different colors
  • Shapes: Rectangles, circles, arrows, lines
  • Freehand drawing: Draw directly on the PDF
  • Stamps: Pre-made stamps like "Approved", "Confidential"
  • Images: Insert PNG, JPG images onto pages

Yes, annotations added with this tool can be edited or removed before downloading. For removing existing annotations from a PDF, use our Remove Annotations tool.

Note: Some PDFs may have "flattened" annotations that cannot be removed without affecting the underlying content.

The only limitation is your browser's available memory. Generally, you can edit PDFs up to:

  • 100+ MB files on modern computers
  • 500+ pages in a single document
  • Complex documents with images and graphics

For very large files, consider using our Compress PDF tool first to reduce file size.
