Combine multiple PDF files into one document
100% Private - Files Processed Locally
Your files never leave your device
Need several PDFs in one file? Upload them, drag to reorder, and merge. I use this whenever I have to send a bunch of separate documents as one attachment â invoices, scanned pages, that kind of thing.
Reorder with the arrows, hit merge, download. It uses pdf-lib in your browser, so your files never get uploaded anywhere.
You can merge as many PDF files as you need. There's no limit on the number of files, though we recommend merging files in batches if you have very many documents.
Absolutely! All PDF processing happens locally in your browser using the pdf-lib library. Your PDFs are never uploaded to any server, ensuring complete privacy.
You can upload PDF files up to 50MB each. The merged PDF maintains the original quality and formatting of your documents.
Yes! You can reorder the PDF files before merging. Simply use the up and down arrows to arrange the files in your desired order before clicking 'Merge PDFs'.
