How Compare PDF works

  1. 1Upload your file — it's validated and sent to our servers over an encrypted connection.
  2. 2Choose your options and click the tool's action button.
  3. 3Your file is processed by a real conversion/processing engine in a background job — not in your browser.
  4. 4Download the result. Both the original and result files are automatically deleted after a short retention window.

Frequently asked questions

What does Compare PDF do?

Compare two PDFs side by side with synchronized scrolling and highlighted text differences.

What file formats are supported?

This tool accepts PDF files and supports uploading multiple files at once.

Are my uploaded files stored?

Files are stored only long enough to process your request, then automatically deleted according to our retention settings — typically within a couple of hours. We never use your documents for anything other than fulfilling your request.

What are the limitations of this tool?

Visual/pixel comparison highlights differing regions; it does not guarantee semantic diffing of complex layout changes.
