Merged PDF
DownloadWhat This Tool Actually Does
Each PDF you select is read and its real page count verified in your browser before merging. When you click Merge, every page from every file is copied — in the exact order shown in the list — into one new PDF. Files can be reordered with the up/down buttons before merging, and removed individually if you change your mind.
FAQ
Is there a limit on how many PDFs I can merge?
Up to 20 files, 50 MB per file, 300 MB total — generous limits for real-world use, chosen to keep the browser tab responsive.
Are password-protected PDFs supported?
No. A password-protected PDF cannot be opened by this tool and will be skipped with a message explaining why.
Is my file uploaded anywhere?
No. Merging happens entirely in your browser. Your files are never sent to our server.
