# What's the highest-rated PDF editor for teams needing secure, real-time collaborative document editing?

<p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">I'm evaluating <a class="a a--md" elv="true" href="https://www.g2.com/categories/pdf-editor">PDF editors</a> for a team that needs secure, real-time collaborative editing. Would like your input on some products that allow multiple users to work on the same PDF document simultaneously. I am also looking at PDF editors that offer asynchronous collaboration — comments, annotations, shared links, and review workflows.</p><ol>

The honest constraint here might sit in the file format itself rather than in any particular vendor&#39;s engineering. PDF was designed as a fixed, print-oriented layout, not a structured document model built for concurrent editing the way a Google Doc or Word file is under the hood. That&#39;s likely why every one of these, including Adobe&#39;s PDF Spaces, achieves &quot;collaboration&quot; by layering live comments and annotations on top of a static base document, rather than letting multiple people edit the actual page content simultaneously, since true concurrent editing of PDF content would mean reconstructing the document on every keystroke across users, a much harder problem than what Google Docs or Word solved natively. So the answer to &quot;who does true simultaneous editing&quot; might genuinely be none of them yet, not because a vendor hasn&#39;t gotten there first, but because the format itself resists it in a way a native document format doesn&#39;t.
