How to use Compare PDF
  1. 01

    Select PDFs

    Choose the two PDF files you want to compare. Both files are read locally.

  2. 02

    Analyze differences

    The comparison engine analyzes page counts, page presence, and extracted page text to generate a mismatch report.

  3. 03

    Download report

    A comparison report is generated in the browser session for review.

Comparison should be explicit about what is compared.

Dual file analysis

The current engine compares document structure, page counts, page presence, and extracted page text.

Page-by-page diff

The report includes page-by-page text mismatch summaries, line-count deltas, and missing-page detection.

Detailed report

A PDF report is generated with changed pages, missing pages, and extracted-text mismatch details.

Privacy first

Compare files locally for standard workflows instead of sending both documents to a remote queue.

Current scope

This route compares page structure and text summaries. Deeper object-level diffing is a later improvement.

Version review

Use comparison for contract revisions, page count verification, and document integrity checks.

PDF comparison without a remote upload queue

Comparing PDF documents is useful for version control, legal review, and quality checks. DocuStitch keeps the current comparison route local in your browser.

The workflow compares page counts, page presence, and extracted page text directly on your device. It produces line-level mismatch summaries while deeper object diffing remains a later improvement.

Local comparison

Comparison logic runs in the browser session for standard workflows.

Privacy focused

Avoid a remote queue for sensitive two-document review.

Detailed reports

Reports page counts, missing pages, changed pages, and extracted-text mismatch summaries.

Fast start

Comparison starts after selecting both files without a raw-file upload cycle.

Frequently asked questions about Compare PDF
What does the comparison report show?

Can I compare more than two files?

Currently, the tool compares two files at a time. For multi-file review, run sequential comparisons.

Practical limits depend on browser memory and the standard DocuStitch limits shown before processing.

Does it work on mobile devices?

Modern mobile browsers can run the workflow, though comparison is usually easier on desktop.
