📄 File & Document Tools
Combine multiple PDF files into one document locally in the order you select them.
Combine two or more unencrypted PDF documents into one file without uploading their contents to a Fieldlet server.
Combine multiple PDF files into one document without uploading them. After selection, move files up or down, remove mistakes, and confirm the exact merge order before browser-local processing begins.
The selected file is processed in browser memory. Keep an original copy and inspect the downloaded result before using it as an authoritative or archival document.
Last reviewed for accuracy:
Scenario: A cover sheet, a five-page report, and a two-page appendix are selected and ordered in that sequence.
Result: The downloaded PDF contains eight pages: cover, report, then appendix.
Each source document is parsed locally and its pages are copied into a new PDF in the displayed file order.
Scenario: The appendix appears above the report in the selected list.
Result: Move the appendix below the report before merging; the output then follows the corrected order.
The merge routine does not infer document meaning. It processes the explicit order shown in the interface.
Fieldlet dynamically loads the PDF library only on relevant routes. It validates bounded inputs, opens each supported document, copies pages into a new document, and serializes the merged bytes for download without rendering page images.
Page content is copied into a new PDF container, but document-level features do not always survive combination exactly. Review navigation, forms, links, accessibility tags, and signatures when they matter.
No. This version uses browser-local PDF processing. Large or complex files can still consume significant device memory.
Yes. Rewriting and copying complex PDF objects can sometimes increase or decrease the final file size.
No. The current merge operation reads and writes the documents in browser memory. Device memory and the stated file and page limits still apply.
