Frequently Asked Questions

How can I Merge PDF Online safely?

To merge files safely, you must use a client-side tool. Our merger runs fully offline directly inside your Chrome or Safari browser using Javascript. Your tax forms, contracts, and proprietary documents are never recorded, uploaded, or seen by our servers.

Can I reorder individual pages, not just entire files?

Yes! We offer a unique dual-mode interface. You can switch from "File Sorting" to "Page Sorting." In Page mode, the tool displays a thumbnail of every single page from every uploaded document, allowing you to drag, drop, and delete at the single-page level.

Is there a file size limit for merging?

Since the processing is bound to your device’s memory, we recommend a soft limit of 50MB per file and a total cap of 500 pages combined. This prevents your browser tab from freezing while constructing the new merged PDF.
