Upload your PDF files, drag to arrange them in the desired order, then click Merge PDFs. The tool combines them using PDF-Lib in your browser. Download the merged file instantly.
Is there a limit on how many PDFs I can merge?
There's no hard limit, but be aware that very large PDFs may be slow to process depending on your device. Each file has a 20MB limit.
Will the merged PDF maintain original formatting?
Yes! PDF-Lib preserves all page content, formatting, images, and links during the merge. The output is a faithful combination of all input PDFs.
Are my PDFs uploaded to your servers?
No. All PDF processing happens entirely in your browser. Your files are never sent to any server, ensuring complete privacy.
