Check layout after export
Render the same page from both versions, then move the overlay across headings, tables, images, and footers. A mismatch here is visual evidence, not a semantic explanation of why it happened.

Frequently Asked Questions About Online Calculators
Does it compare all pages automatically?
You choose a page so the browser can keep the visual workspace responsive. Move through the page numbers you need to inspect.
Does it OCR scanned PDFs?
No. It renders pages as they are and does not extract or recognize text.
Will my original file be changed?
The result is downloaded as a separate file. Keep your original until you have checked the Rendered PDF page comparison.
What should I check before using the result?
Open the Rendered PDF page comparison in the application that consumes it and spot-check the parts that matter to you; the original file stays untouched if you need to re-run with different options.
Before downloading the result
Compare the Rendered PDF page comparison with the original while both are fresh; destinations differ, and a quick check here saves a re-upload later.
