Combine several PDFs into one document
Merge PDF stitches multiple PDF files together into a single document, preserving each file’s pages in the order you select them.
Select two or more PDFs — up to twenty — and the converter appends them end to end. The merged file keeps each source document’s content but not necessarily its bookmarks or metadata.
Useful situations
- Assemble a report from separate chapter files.
- Bundle scanned pages into one submission.
- Combine invoices or receipts for a single upload.
How to use Merge PDF
- Select at least two PDF files — the order you pick them is the merge order.
- Convert — the server concatenates the documents.
- Download the merged PDF and verify the page sequence.
What to expect
- Merge order follows selection order — re-select files if the sequence is wrong.
- Bookmarks, forms, and metadata may not merge cleanly from all sources.
- Password-protected PDFs cannot be merged without removing protection first.
Frequently asked questions
How do I control the page order when merging PDFs?
Pages follow the order in which you selected the files. If the result is wrong, clear the selection and pick the files again in the desired sequence.
Is there a limit to how many PDFs I can merge?
Up to 20 files per merge, each within the standard size limit. For very large batches, merge groups first and then merge the results.
Does merging change the content of the pages?
No — pages are copied intact into the new document. Only container-level features like bookmarks may differ.
