How we handle your data

Compare PDF

Compare two bounded technical PDFs side by side to review page and text changes manually. No automatic diff, validation or converted output is made.

A practical guide

Compare the record pages with a human check.

  1. Choose two PDF records within the per-file size and page caps.
  2. Inspect corresponding page renderings and readable text side by side.
  3. Record any changes you observe and retain both originals for reference.

Try this example

Compare two six-page equipment reports, each at or below 10 MiB. Inspect the calibration notes and measured values page by page; the viewer does not calculate a text or image diff.

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 limited manual inspection, not automatic diffing, validation or PDF conversion.

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.
