What does it mean to compare PDF files?

Comparing PDF files means viewing two PDF versions side by side (or in a diff view) to spot changes in text, layout, or images—for example, a draft vs. a revised version or a before-and-after proof. In Kreatli, you can upload multiple PDFs to a project and review them together with comments and annotations, so your team can see exactly what changed and give precise feedback in one place.

Do I need a Kreatli account to use this page?

You can use this page in your browser without signing in. If you are already signed in to Kreatli and your trial or subscription is not active, you will need to start a 7-day trial or choose a plan to use the tool here—you add a payment method during secure checkout and are not charged subscription fees during the trial. People who open a review link you share still do not need a Kreatli account.

How do I compare two PDFs in Kreatli?

Upload both PDFs to a Kreatli project and open them in the review interface. You can switch between them or view them in the same project so reviewers can reference both versions. Add comments and annotations on either PDF, pinning feedback to the exact page and location. All feedback stays in one thread so nothing gets lost between versions.

Can I compare PDFs with different page counts?

Yes. Kreatli supports reviewing PDFs of any length. When comparing versions with different page counts, you can annotate each file by page. Comments are tied to the specific PDF and page, so it's clear which version and which spot each piece of feedback refers to. Use the project to keep both versions visible to the team.

Why compare PDFs in Kreatli instead of a standalone diff tool?

Comparing PDFs in Kreatli keeps review in one place with your video, images, and other deliverables. You get a single project, one set of review links for clients, and one approval workflow. Reviewers can add comments and markup on either version, and all feedback is tracked in one thread—no juggling between a diff tool and a separate review app.

Can clients compare PDF versions without creating an account?

Yes. Send your client a secure Kreatli review link that includes both PDFs. They can open the project, switch between versions, add comments and markup on either file, and submit feedback without signing up. All comparisons and feedback stay in one place for your team.

How does comparing PDFs help creative and legal workflows?

Comparing PDFs helps you catch changes between contract drafts, design revisions, or document versions. When feedback is pinned to the exact page and spot, writers and designers know precisely what changed and what to fix. Keeping both versions in one Kreatli project with resolution tracking speeds up approvals and reduces revision cycles for decks, contracts, and layouts.

Upload new versions to keep the review going
