How to Merge PDF Files
Upload two or more files, and drag the file items to change the display order of the merged files.
Check page orientation before merging. If some source PDFs are landscape and others portrait, the merged file will keep each page's original orientation rather than standardizing it.
Remove unwanted pages first. If a source file has pages you don't want in the final document, use [Split PDF](/split-pdf) or a page-delete tool to trim it down before merging.
Double-check file order.Since the merged output follows the order you set, it's best to preview the thumbnail arrangement again before generating the result.
Common Questions
How many PDFs can I merge at once?
Merge multiple PDF documents in one operation and arrange them in any order. The number of files and the size of each file depend on your subscription plan.
Will merging affect the quality of my PDFs?
No. Merging only combines pages into one file - it doesn't re-compress or alter the content, so text, images, and formatting remain precisely as they were in each source file.
Can I reorder pages once merging, or only before?
Page order is set before generating the result, based on how you arrange the file thumbnails. To reorder pages afterward, upload the merged file again, use [Split PDF](/split-pdf) to extract and rearrange sections, then merge them again.
Can I merge PDFs with various page sizes or orientations?
Yes. Pages keep their original size and orientation after merging - this tool doesn't force every page into a uniform layout.
Is it possible to merge password-protected PDFs?
You'll need to unlock or remove the password from any protected file before merging, since this tool needs to read the page content directly.
Can I split a merged PDF back into individual files later?
Yes. Open [Split PDF](/split-pdf) whenever you want to divide a merged document into individual files or extract specific pages.
