A PDF is a document container, not just a collection of images. Pages can contain selectable text, forms, metadata, and signatures. Changing one part may affect another.

Decide what you need to keep

Merging or extracting pages creates a new document. Open the output and check page order, orientation, links, and form fields. If a PDF is digitally signed, editing it can invalidate the signature even when the pages still look the same.

Handle private documents deliberately

Check whether a tool processes files locally before opening contracts, IDs, or financial records. A downloaded copy may retain metadata or embedded content you did not intend to share. Inspect the output, not only the preview.

  • PDF Page Counter and Info — Read a PDF to see its page count, page sizes, version and document information.
  • PDF Merger — Join several PDFs into one document, in the order you set.
  • PDF Page Extractor — Keep only the pages you choose from a PDF and download the rest as a new file.
  • PDF Signature Checker — Inspect the digital signatures embedded in a PDF.
  • Text to PDF — Write plain text out as a PDF, with wrapping, page size, margins and page numbers.
