Merge PDF
For packets, exhibits, and review bundles.

Combine supporting documents into one review-ready PDF while keeping the source files on your device. This is useful for application packets, client handoffs, and internal bundles where page order matters.

Merge PDF workflow notes

Merging PDFs is a simple task on the surface, but a clean combined document still takes a little planning. The best merged files follow a clear order, use logical naming, and make it easy for the recipient to understand what is included and why.

Best use cases

  • Assemble application documents, supporting records, or signed paperwork into one packet.
  • Create a single handoff file for a client, manager, or reviewer.
  • Bundle appendices, exhibits, and cover material for internal review.

Before you share

  • Place cover material first if the file needs context.
  • Keep source files separate in case you need to reassemble the packet later.
  • Use bookmarks or page numbers later if the packet becomes large.

Practical limits

  • Merge PDF works on the file you provide, but it cannot correct source problems such as missing fonts, broken scans, or incomplete document structure on its own.
  • Performance depends on the memory and CPU available in the current browser tab, so very large files or image-heavy PDFs can still take longer to finish.
  • The browser-based workflow keeps files private and fast to process, but you should still inspect the final PDF before sending it to a client, portal, or records team.

Every tool runs in your browser, so there is no upload queue slowing the job down.

That is useful for private work and for large files on limited bandwidth.
