Merge PDF Files Online

What this tool does
Combine multiple PDF documents into one PDF in the order you choose. Useful for combining reports, invoices, scanned pages, application documents, or other related PDFs into one file.
How to use merge pdf files online
- Choose two or more PDF files.
- Review the selected files and remove any you do not want.
- Merge the files and download the combined PDF.
Browser-based processing
PDFiva's current tool workflow is designed to process the selected document in your browser. The front-end application does not include a PDFiva upload endpoint for this operation. Your device performs the work, so available memory, processor speed, browser support, and document complexity can affect processing time.
Before you download
Open the result and check important documents before sharing or submitting them. PDF files can contain forms, fonts, annotations, encryption, embedded content, and other features that vary from one document to another.
Frequently asked questions
How many PDFs can I merge?
The browser application accepts multiple PDF files. The practical limit depends on your device memory and the size and complexity of the documents.
Can I remove a PDF before merging?
Yes. The merge workflow lets you remove a selected file before creating the combined PDF.
Are my files uploaded?
The current front-end merge workflow processes the selected PDF bytes in the browser rather than sending them to a PDFiva server.
