How to use Compare PDF
A clear browser-session workflow for compare PDF work.
The interface should make the route visible: select files, perform the operation, and download the output from the same session.
02
Analyze differences
The comparison engine analyzes page counts, page presence, and extracted page text to generate a mismatch report.
03
Download report
A comparison report is generated in the browser session for review.
Why local processing matters
Compare the processing route before using sensitive documents.
DocuStitch labels supported workflows around the browser session rather than hiding the path behind a generic cloud promise.
DocuStitch supported workflow
- Files selected on device
- Operation runs in browser session
- Output downloads from the tab
Typical cloud workflow
- Files uploaded to remote queue
- Processing depends on server retention policy
- Output returned after transfer
How it works
Comparison should be explicit about what is compared.
Dual file analysisThe current engine compares document structure, page counts, page presence, and extracted page text.
Page-by-page diffThe report includes page-by-page text mismatch summaries, line-count deltas, and missing-page detection.
Detailed reportA PDF report is generated with changed pages, missing pages, and extracted-text mismatch details.
Operator notes
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.
01
Local comparison
Comparison logic runs in the browser session for standard workflows.
02
Privacy focused
Avoid a remote queue for sensitive two-document review.
03
Detailed reports
Reports page counts, missing pages, changed pages, and extracted-text mismatch summaries.
04
Fast start
Comparison starts after selecting both files without a raw-file upload cycle.
FAQ
Frequently asked questions
Everything you need to know about Compare PDF.
What does the comparison report show?
The current report includes page counts, page-by-page presence analysis, changed-page detection, line-count deltas, and extracted-text mismatch summaries.
Can I compare more than two files?
Currently, the tool compares two files at a time. For multi-file review, run sequential comparisons.
Is there a file size limit?
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.
