Merge PDF JavaScript Overview
The Merge PDF JS module allows users to combine multiple PDF files into a single PDF document.
Some key features of the Merge PDF JS module include retaining page numbering, eliminating duplicate fonts for improved performance, and generating a table of contents for the merged documents. Additionally, it offers properties like page size to set a consistent page size across the merged document and page orientation to choose between portrait and landscape orientations, ensuring that the final output meets specific formatting requirements.
This JS module is useful for organizing content and reducing the number of separate files by merging them into one.

Bool Default: FalseWhen the StoreFile parameter is set to True, your converted file is written to ConvertAPI’s encrypted, temporary storage and made available via a time-limited secure download URL, valid for up to 3 hours. After this period, the file is permanently deleted.
When StoreFile is set to False, conversion happens entirely in-memory. The raw file bytes are streamed back in the API response without touching disk or external storage, ensuring maximum security and zero persistence so that only you can access the content.
