How to review, edit, annotate, watermark, and compare a PDF
Begin by identifying whether the task changes the document, adds visible material, or only reviews differences.

Review the source before changing it
Use PDF Reader to navigate thumbnails, zoom into details, and check page orientation. Keep the original open for comparison when making important changes.
- Open the PDF in PDF Reader.
- Review every relevant page.
- Decide which focused editing task is actually required.
Choose the right tool for visible additions
Edit PDF places new text, JPG or PNG images, highlights, freehand drawings, rectangles, ellipses, and lines on one or more pages. Annotate PDF is a simpler workflow for one page-width highlight band with an optional note. Watermark PDF applies repeated visible text across every page.
- Choose Edit PDF for several positioned objects or pages.
- Choose Annotate PDF for one focused highlight and note, or Watermark PDF for repeated text.
- Preview every affected page and review the downloaded copy.
Compare document versions
Compare PDF renders both documents and reports visual page differences. It can reveal changed appearance but cannot decide whether two documents have the same legal meaning.
- Choose the earlier and later PDFs.
- Run the visual comparison.
- Inspect every reported difference in context.

What can I add with Edit PDF?
You can add text, JPG or PNG images, highlights, freehand drawings, rectangles, ellipses, and lines across the required pages before saving one copy.
Can Compare PDF prove that documents are legally identical?
No. It is a visual comparison tool, not a semantic, cryptographic, or legal verification service.
