What Compare Pdf does

Generate a visual diff between two PDFs (ZIP output).

Use this tool when you need a quick, browser-based way to process a document and download the result. Depending on the tool, your output may be a PDF, a ZIP archive, or an editable file format.

PDFMaple runs with a simple workflow: upload → run → download. No complicated settings unless you need them.

When to use Compare Pdf

  • Check differences between two versions of a document.
  • Review edits before approving a PDF.
  • Spot changes in contracts, policies, or reports.

How it works

  1. Upload your file(s).
  2. Click Run tool.
  3. Download the result.

Tips for best results

  • Large files can take longer—wait for processing to finish before leaving the page.
  • For best results, start from the highest-quality source file you have.
  • If a result looks off, try again with a different source export (or run Repair first).

Troubleshooting

  • If processing takes longer than expected, keep the tab open and avoid switching networks.
  • If the output looks incorrect, retry with a higher-quality source (or run Repair PDF first).
  • If downloads are blocked, check your browser’s download settings (or try a different browser).
