About the Compare PDFs

Compare PDFs runs a text-level diff between two versions of a document, highlighting what was added, removed or changed — useful for reviewing contract redlines, checking whether a revised agreement matches the previously agreed terms, or spotting edits between draft versions of a report.

Rather than manually scanning two long documents side by side looking for subtle wording changes (a slow and error-prone process, especially in legal or financial documents where a single changed number or clause matters), this tool surfaces every textual difference automatically so nothing gets missed.

Frequently Asked Questions

Does this compare the visual layout of the PDFs or just the text?

The comparison is text-based, focused on identifying added, removed or changed wording between the two documents — visual-only differences like font or color changes that don't affect the underlying text won't be flagged.

Can I use this to check if a contract's final version matches the draft I approved?

Yes, this is one of the most common uses — upload the draft you approved and the final version you received to instantly see whether any clauses were altered before signing.

Is my data safe when I use Compare PDFs?

Most AIVEXA tools run entirely in your browser (client-side), which means your files and inputs are processed on your own device and are not uploaded to a server.

Can I use Compare PDFs on mobile, and is it free?

Yes — it works on any modern browser (desktop, Android or iOS) without installing an app, and it's free to use with no signup or watermark.
