Merge PDF files in the exact order you choose
Combine native PDF pages without turning them into screenshots, then download one high-fidelity document.
The merge workflow copies complete pages from each source PDF into one output file. Page dimensions, rotation, vector artwork, selectable text, and embedded page content are retained instead of rasterizing every page.

Merge PDF questions
How many PDFs can I merge?
You can combine up to 20 valid PDFs, 50 MB per file, with a maximum of 200 pages in the merged output.
Does merging reduce PDF quality?
No rasterization is used during merging. Native pages are copied into the result so their original visual quality is retained.
Can I rearrange PDFs before merging?
Yes. Drag each file into the exact order you want before creating the output.
Are merged files uploaded?
Choosing a file does not upload its contents to PDFArrow. Processing runs in this browser, and the result is downloaded directly to this device.
Can I merge password-protected PDFs?
Not directly. Remove a password first only when you know it and are authorized to modify the document.
