Practical guidance

Replace compatible PDF text and add visible content

Wait for text detection, choose Edit existing text and click or tap a compatible run, or choose a run from Find text on this page. Double-clicking focuses the replacement field. Source replacement changes the PDF text object; Add text creates a separate new text box.

Add text and images where needed

Place new text boxes or supported images on selected pages, then move and resize them using the available controls.

Mark up pages with highlights, drawings, and shapes

Use the supported highlight, drawing, and shape tools for visible review marks and simple additions.

Review additions across multiple pages

Move between page previews, inspect each addition, and reopen the finished PDF to confirm the result.

About this tool

Choose source-text replacement or new content

Compatible source runs can be replaced directly. New text boxes, JPG or PNG images and review marks have separate move, resize, rotation, layering and duplication controls. Undo and Redo include source replacements.

Useful for

  • Add reference text, dates, labels, images, highlights, or shapes.
  • Build and review additions across multiple pages.
  • Create an updated copy without changing the original source file.

Good to know

  • Source replacement supports compatible visible single-line text runs. Scans, grouped artwork, complex scripts and page-wide reflow are unsupported. Edit paragraph and wrap supports eligible horizontal Latin text inside a reviewed area and rejects overflow or collisions. Missing font characters block export.
  • Saving any edit invalidates an existing cryptographic signature.
  • PDF forms with named fields are a different workflow from free-position overlay editing.
