How to merge multiple PDF files

Merging PDFs means combining several separate files into one result. The important decisions are file order, whether you need to remove pages first, and whether the merge should happen without uploading the files.

Use a merge tool when the files are already separate

If you have several reports, invoices, scans, or appendices and want one combined PDF, you need a merge workflow. A merge tool keeps each file intact and places them into one output in sequence.

Review file order before export

The final document follows the order of the files you add. If an appendix should come last, or a cover page should come first, change the file order before you download the merged result.

Remove unwanted pages first when needed

If one PDF contains blank pages, duplicates, or a section you do not want in the final result, clean that file first with Remove PDF Pages. Then merge the cleaned files in Merge PDF.

Merge is different from split

Split PDF creates a new file from selected pages inside one document. Merge combines several files. If you only need pages 3-6 from one PDF, split first, then merge only if multiple outputs need to become one file.

Browser-side merging helps with privacy

When a merge tool runs in the browser, the selected PDFs do not need to be uploaded for the core merge flow. That is useful for internal documents, drafts, invoices, and other files you prefer to keep on your device.
