What you get for free
Upload two PDFs of up to 30 pages each and the comparison runs immediately, with no account. The result is the same as on paid plans: a change list with page numbers, a redlined PDF you can download, and a side-by-side view with synced scrolling. The free tier is limited by page count and by a daily cap per network, not by features.
A free account raises the page limit to 100 pages per document and gives five comparisons a month. That covers most individual use: a lease, a contract draft, a returned form.
What free online comparison tools usually get wrong
- Comparing page by page, so one inserted sentence lights up every later page.
- Reporting page numbers and running headers on every page as changes.
- Producing a screenshot with highlights but no list, so you still read the whole document.
- Storing your upload. Read the privacy policy of any tool you send a contract to.
How this one handles your files
Both PDFs are processed in memory for the length of the request and discarded when the response is sent. Nothing is written to permanent storage, there is no document library, and there is no "recent comparisons" list because nothing is kept. The privacy policy describes exactly what is and is not stored.
When free is not enough
Teams that compare documents every week want volume, larger documents and an API. The Business plan covers volume; Enterprise covers API keys, 300-page documents and private deployment inside your own network. The engine is the same on every tier.
Try it on your own documents. Upload two versions on the homepage. Documents up to 30 pages need no account, and nothing is stored.
