Edit PDF text and images

Last updated: by PrimePDF Support Team

You do not need the original source file to update a PDF. PrimePDF lets you edit text, replace images, highlight content, and add comments in the browser, with no download required.

Open and edit a PDF

Launch Edit PDF, upload your document (up to 100 MB), use the toolbar to adjust text or images, then download or share the updated file.

Editor features

  • Add Text: add new text anywhere on the page.
  • Highlight passages in several colors, with optional notes for context.
  • Add comments: leave notes, suggest changes, and tag teammates to keep feedback organized.
  • Sign PDF: fill form fields and apply your signature.

Text and image editing

Click existing text to correct it, use Add Text to place new content anywhere, or replace images in a few steps. Changes sync across desktop, tablet, and phone.

Beyond quick edits

When you need heavy rewriting, send the file through PDF to Word make your edits, then convert back with Word to PDF.
