Merge PDF Online
This tool combines PDF files into one document. Add two or more PDFs, review the visible order, move files up or down when needed, and run the merge; the output name is based on the first valid PDF.
PDF files
0 valid, 0 excluded, 0 B
How To Convert
- Upload two or more PDF files.
- Review the visible order and move files up or down if needed.
- Make sure at least two valid PDFs remain in the list.
- Choose Merge PDF and download the finished file.
Format Notes
- Upload two to twenty PDF files; total size and total page count are checked before processing.
- The output is one PDF with pages appended in the visible file order; Download all returns that PDF directly.
- Password-protected or encrypted PDFs are marked as failed and excluded; if fewer than two valid PDFs remain, the job ends with a clear error.
- Best for combining contracts, applications, scans, or several documents that need to be sent as one PDF.
- Not for rearranging pages inside one PDF, compression, editing page text, or merging images directly before converting them to PDF.
- Use up and down buttons to control file order before submitting.
- Non-matching files are filtered locally, while encrypted PDFs are marked failed on the server.
- The total page limit keeps very large merge jobs bounded.
- Because there is one result, Download all returns the PDF directly instead of a ZIP archive.
File Privacy
Files are used only to merge PDFs and provide a temporary result; file contents, filenames, and document order are not sent to analytics.
FAQ
What order does the merged PDF use?
The merged file follows the visible selected-file list. Use the move controls before starting when a document should appear earlier or later.
What happens to a password-protected PDF?
It is kept in the job as a failed file and excluded from the merge. If two or more valid PDFs remain, the job still completes.
Why are at least two PDF files required?
Merging only has a result when two or more documents are combined. For one PDF, use the file as-is or split its pages instead.
How is the output PDF named?
The filename starts with the first valid PDF in the ordered list and adds a merged suffix so the starting document is clear.
Can I merge images with PDFs here?
This action accepts PDFs only. Convert images to PDF first, then use Merge PDF to combine the resulting documents.
