How we handle your data

Compare PDF

Compare PDF revisions side by side: review two short versions beside one another before routing the next one. Inspection only, with no automatic diff file.

A practical guide

Inspect revisions before continuing the workflow.

  1. Open two PDFs within the stated size and page caps.
  2. Compare corresponding pages and readable text in the side-by-side view.
  3. Note changes yourself and continue with the correct source file.

Try this example

Compare two four-page checklist revisions, each no larger than 10 MiB. Review the same page positions and inspect the changed step text; the tool does not detect or mark differences for you.

Before

  • Original PDF
  • Revised PDF

After

  • Side-by-side pages
  • Extracted text
Input and expected output for this task. Illustrative example.

Before you start: This is inspection only: no automatic diff, merged result or converted output file.

Inspect PDF metadata
What you get

View two PDFs side by side and compare their extracted text. This does not automatically identify visual or semantic differences.

Limits and important details

Two PDFs, each up to 10 MiB and 6 pages; 4 MP rendered page limit and 100,000 extracted text characters per page. This is a local side-by-side review of pages and extracted text. It does not run OCR, download a combined result, or automatically detect visual or semantic differences.

Example

Choose two PDFs, each no larger than 10 MiB and six pages. Inspect corresponding page renderings and visible text side by side, and note any differences yourself. This is not automatic diffing and creates no converted output PDF.
