How to edit PDF files
Choose the page that matches the part of the PDF you need to change. PDF Metadata Editor handles Document Info and XMP metadata. PDF Page Editor handles pages, form fields, annotations, bookmarks, and a signature image. Watermark PDF puts a text or image mark on selected pages. PDF Page Editor and Watermark PDF let you review a summary or preview before export. The broader PDF Tools category also covers converting, merging, splitting, repairing, and extracting text.
Choose a PDF editing tool by the change you need
Change stored document details with PDF Metadata Editor. It reads and edits Document Info fields including Title, Author, Subject, Keywords, Creator, Producer, and dates. It also detects XMP metadata, shows existing values, and includes a change report with the exported PDF.
Change page structure and page-level content in PDF Page Editor. It can delete, reorder, rotate, and crop pages; add page numbers and repeated headers or footers; fill and flatten AcroForm fields; remove annotations; add flat bookmarks; and place a signature image. Review the change summary before exporting.
Put a visible mark on selected pages with Watermark PDF. Choose a text or image watermark, set the page range, and adjust position, scale, rotation, opacity, layer order, margins, and repeat pattern. Preview the watermark before exporting.
What PDF metadata editing changes
Metadata is stored with the PDF rather than drawn on a page. Changing it can update a title or author while leaving the page content in place:
Title: Q3 invoices
Author: Finance
Title: Q3 invoices
Author: Finance Team
PDF Metadata Editor also detects XMP metadata. It shows warnings for signed, encrypted, malformed, or unsupported PDFs before you edit or export.
What PDF Page Editor changes
Use PDF Page Editor for changes to pages or page-level objects. Delete an extra page, reorder the sequence, rotate a page with the wrong orientation, or crop its boundaries. The same page also handles page numbers, repeated headers and footers, AcroForm fields, annotations, flat bookmarks, and a signature image.
When several edits are involved, review the change summary before exporting. PDF Page Editor exports a new PDF after the changes.
When to add a watermark to a PDF
Use Watermark PDF when the mark must appear on the page itself. Select the page range, choose a text or image watermark, then set its position, scale, rotation, opacity, layer order, margins, and repeat pattern. Preview the result before exporting.
Use PDF Metadata Editor for labels stored in the PDF's file information. Use PDF Page Editor for page order, cropping, fields, annotations, bookmarks, or a signature image. Go to PDF Tools when the job is compressing, converting, merging, splitting, redacting, repairing, or extracting text.
Typical jobs
For an invoice, update the Author and Subject fields before filing the PDF with its corrected document information.
For a reviewed document, remove an extra page, rotate a scanned page, add page numbers, and flatten completed AcroForm fields before exporting.
For a marked copy, place a text or image watermark on selected pages, adjust its opacity and position, and preview the result before export.
Where to start if the PDF edit is unclear
Choose PDF Page Editor for pages, fields, annotations, bookmarks, or a signature image. Choose PDF Metadata Editor when the request names Title, Author, Subject, Keywords, Creator, Producer, dates, or XMP. Choose Watermark PDF when the mark must be visible on selected pages.
