Processed on your device. Your PDFs are never uploaded.
Combine PDFs in the order you need
Merge separate documents into one PDF without printing or converting pages to images. Each source document contributes all of its pages in their original order. Reorder the files before merging to arrange the final document.
Local processing and practical limits
Your PDFs are processed locally and never uploaded. Choose up to 20 files, no larger than 50 MB each or 200 MB combined. Large or complex documents may take longer and require more browser memory. Encrypted, password-protected, corrupt or unsupported files are rejected.
Review the merged document
Download and review your combined PDF before sharing it. This tool combines pages; it does not compress documents. Document-level bookmarks, digital signatures and interactive form behavior are not guaranteed to carry over.
How to use
- Choose at least two PDF files or drop them into the workspace.
- Arrange the files by dragging them or using Move up and Move down. Remove any files you do not need.
- Select Merge PDFs, then download the merged PDF.
Frequently asked questions
How do I merge PDF files?
Choose two or more PDFs, arrange them in the desired order, select Merge PDFs and download the combined document.
Are my PDFs uploaded?
No. Parsing and merging happen locally in your browser. Your documents and filenames are not sent to analytics.
Can I reorder files on mobile?
Yes. Use the Move up and Move down buttons to arrange files without dragging.
What are the file limits?
You can combine up to 20 PDFs, with a maximum of 50 MB per file and 200 MB for the complete batch.
Can I merge password-protected PDFs?
Encrypted or password-protected PDFs are not supported. Use unlocked copies that you are authorized to access.
Will page order or quality change?
The merger copies PDF pages without rasterizing them. Files follow the visible list order, and pages within each file keep their order. It does not promise to preserve document-level signatures, bookmarks or interactive forms.
