How to use Merge PDF
Merging creates one continuous PDF while preserving each source page. Choose files in the order they should appear in the final document.
Steps
- Choose two or more PDF files.
- Review the displayed file order.
- Merge and download the combined PDF.
Formats, limits, and accuracy
Encrypted or damaged PDFs may not load. Large documents use more browser memory, so combine smaller batches if your device becomes slow.
Frequently asked questions
Are my PDFs uploaded?
No. The browser reads and combines them locally.
Does merging reduce quality?
No. Existing PDF pages are copied into a new document without rasterizing them.
Practical notes
The selected file order becomes the page order in the merged download.
Keep source files until you have checked every page of the result.
