What is included in the merged file?
Pages are copied into a new PDF in the order shown above. Merging can alter or omit document-level features such as bookmarks, form fields, annotations, layers, or attachments. A merge changes the document and invalidates any existing digital signatures. Review the result before relying on it.
Limits and protected PDFs
To limit browser memory use, this tool accepts up to 20 files, 25 MB per file, 75 MB combined, and 250 pages. The output is capped at 125 MB. Password-protected or damaged PDFs may not open. Keep important originals; this tool creates a new file and does not edit the sources.
Frequently asked questions
Are my PDFs uploaded?
No. The selected files are read and merged locally in your browser; the PDF bytes are not sent to a conversion service.
Can I change the order of pages?
Yes. The page list shows the final order. Use the Up and Down buttons beside a page before creating the merged file.
Will forms, bookmarks, or signatures be preserved?
Page content is copied, but document-level features may be altered or omitted. Any digital signature on a source PDF is invalidated by merging.
Privacy note: all selected PDF files stay in your browser. PDF library license and dependency notices.
