Best use cases

Worked example

Batch packet merge example

A user assembling one packet from several signed forms can select the files in the desired sequence and export a single merged PDF for download.

• Put the files in final order before selecting them.
• Open the merged result once after export to confirm the page sequence is correct.
• Keep the original PDFs in case one source needs to be swapped and merged again.

Merge PDF is strongest when file order is already decided and the goal is one clean browser-side combined document.

Methodology

• The tool loads each selected PDF in the browser and appends pages into a newly created output document in selection order.
• Each source file keeps its own internal page order, so the merged output is deterministic as long as the input order stays the same.
