What is merge pdf?
PDF merging combines pages from two or more PDF files into a single new document. PDFora keeps the pages of each source file together and follows the file order shown in the upload list.
How to use Merge PDF
- 1
Add at least two PDF files.
- 2
Use the reorder controls or drag on supported desktop browsers to set the file sequence.
- 3
Select Merge PDF and wait for the combined document to be created.
- 4
Download the merged PDF and confirm the page sequence.
Why use this tool?
Merging is useful when related material arrives as separate files but needs to be shared, reviewed, printed, or submitted as one document. Common examples include reports with appendices, invoice batches, forms with supporting documents, and scanned sections of the same record.
How PDFora works
PDFora validates the selected files and options, processes the task locally inside your browser, and creates the download on your device. Document contents are not sent to PDFora servers.
Common ways to use Merge PDF

- Create one submission from several scanned sections
- Collect invoices or receipts into one PDF
Tips for better results
- Name your source files clearly before upload if you are working with many documents.
- Set the final file order before processing; the merge follows the displayed sequence.
- If a source PDF is sideways, rotate it first for a cleaner final document.
- Compress the merged result afterward if the combined PDF is larger than your target upload limit.
Frequently asked questions
Can I change the PDF order before merging?
Yes. Use the on-screen reorder controls. Desktop drag-and-drop is also supported where the browser provides it.
Does merging edit page content?
No. The merge operation copies existing pages into a new PDF rather than redesigning their content.
How many files can I merge at once?
The current request limit is 20 uploaded files, subject to the combined upload-size limit.
Can I merge password-protected PDFs?
No. Password-protected PDFs are not accepted in this version.
