Can I focus only on text changes?

Choose text-only comparison when supported; graphical differences may be excluded.

Can scanned documents be compared?

Visual comparison can examine scans; text comparison may require OCR.

Specify the relevant page ranges in each document when supported.

What happens when pages change order?

Some methods match similar pages and identify moved pages.

Will the report definitely catch every important change?

Do not assume completeness; review its scope and findings against the sources.

Can I complete the operation and download a file on this page?

This version supports file selection and checks of file type, size, and count. Processing is not connected, so it does not convert, edit, or generate downloads. The guide describes a workflow in an application that supports the operation.

Which file types and sizes can I select?

This tool accepts PDF file extensions. You can select up to 20 files, with a 25 MB per-file limit and 100 MB total. Checking an extension does not verify that the file contents are valid or undamaged.

Are my selected files sent to a server?

In this version, file contents are not read or uploaded. Selections stay in the tab’s memory and are cleared on refresh. File names, extensions, and sizes are used only to display and check your selection.
