How to Merge PDF Files
- Choose two or more PDF files.
- Arrange the files in the order you want.
- Merge the PDFs and download the combined document.
Combine Multiple PDFs into One File
Each selected PDF is appended to one combined document in the displayed order. All pages from the first PDF come before the pages from the second PDF, followed by each remaining file.
Change the PDF Order Before Merging
Use Move up and Move down to arrange the selected PDFs. The displayed file order determines the final page order, and you can remove any file you do not want to include.
What Happens to PDF Quality?
Savezly merges PDF pages structurally rather than intentionally rendering them into images. The output is rebuilt as a new PDF document, so its file size can differ from the combined source files.
PDF Features and Compatibility
Visible page content, dimensions, and rotation are retained for supported PDFs. Advanced document features such as bookmarks, forms, metadata, attachments, or internal document links may not be preserved in the merged file.
Private, Browser-Based PDF Merging
Your selected PDFs are processed locally in your browser and are not uploaded to Savezly for merging.
Merge PDF Limits
You can merge 2–20 PDF files. Each file may be up to 25 MiB, with a maximum combined input of 50 MiB and 100 total pages. The generated PDF may be up to 100 MiB. Password-protected PDFs are not supported.
