PDF Editing and Annotation Tools
Choose tools for text overlays, visible signatures, interactive forms, PDF comparisons and page presentation. Page numbers, text or image watermarks, cropping and assignment covers each have a focused workflow and stated limits.

Choose an editing, form or signature tool
Annotate pages or fill a form
Edit PDF adds text, outline rectangles and highlights without replacing the original text. PDF Forms fills supported interactive fields; it does not create new form fields or support XFA forms.
Sign or compare documents
Sign PDF places a visible drawn, typed or uploaded signature without a digital certificate. Compare PDF finds selectable-text changes and optional visual differences between two documents.
Finish a document for sharing
Add page numbers or a text/image watermark, trim visible margins or generate a one-page assignment cover from your details. Cropping is not redaction, and the cover helper does not write coursework.
Frequently asked questions about edit PDF tools
Can I edit existing PDF text on this page?
The category currently lists only editing capabilities that are production-ready. Full existing-text editing is not presented here as a live feature.
Does the assignment cover tool write coursework for me?
No. It formats only the student details you enter and does not invent assignment content, grades, citations or submission rules.
Should I keep an unedited copy?
Yes. Keep originals and verify page numbers, watermark placement, crop boundaries or student cover details before final submission or sharing.
