Use it to bring together project reports, class notes, invoices, application forms, meeting documents, or scanned paperwork. Add your files, arrange them in the right sequence, and create a single PDF that follows your preferred order.

Frequently Asked Questions About Merging PDFs
Learn how the Merge PDF tool works and what to check before combining your documents.
How do I merge PDF files online?
Open the DoMorely Merge PDF tool, select at least two PDF files, arrange them in your preferred order, and click Merge PDF Files. When the process finishes, download the combined PDF to your device.
Can I change the order of PDF files before merging?
Yes. After selecting your files, use the up and down controls beside each filename. The tool combines the PDFs in the order displayed in the selected-file list.
Are my PDF files uploaded to DoMorely?
The merge operation runs in your browser, and the selected PDF contents are not sent to the DoMorely server by this tool. The PDF library is loaded from a third-party CDN, so your browser must be able to load that library. Avoid using a shared or untrusted device for confidential documents.
Can I merge more than two PDF files?
Yes. You can select multiple PDFs at once and add more files before merging. The number and size of files your device can process depend on available browser memory and system resources.
Will merging PDFs reduce their file size?
Not necessarily. Merging combines documents into one PDF but does not automatically compress their contents. If you need a smaller file, use a dedicated PDF compression tool after merging.
Will the merged PDF keep the original page order?
The tool preserves the page sequence inside each selected PDF and combines the documents according to the file order you set before starting the merge.
Why might a PDF fail to merge?
A file may be damaged, password-protected, unsupported, or too large for the available browser memory. Try opening the file first, removing password protection where you are authorized to do so, or processing fewer files at a time.
