Why merge your PDFs on PDFDocks?
Most PDF merging websites work the same way internally: you upload your file to a server, the server processes it, and then sends it back for download. During that journey, your document—which might contain payslips, contracts, medical records, or any sensitive information—travels across the internet and remains, even if only for a few seconds, in the hands of a third party. PDFDocks works differently: PDF merging happens with JavaScript, right inside your own browser. Your files never leave your computer or phone at any point—there's no upload, no server in between, and nothing to delete afterward because it never went anywhere. This isn't just a theoretical privacy issue: it also means you don't depend on your internet connection speed for uploading large files, nor on whether the server is overloaded with other users at that moment. The process is practically instantaneous.
Is my data really private on PDFDocks?
+
Yes, completely. Your PDF files are processed entirely in your browser using JavaScript. They never leave your device and are never sent to our servers. We cannot access, store, or see your documents in any way.
Can I merge PDFs on any device?
+
Yes, as long as your device has a modern web browser (Chrome, Firefox, Safari, Edge, etc.). PDFDocks works on Windows, Mac, Linux, iPhone, and Android. No software installation needed.
Is there a file size limit?
+
Your browser's memory is the only limit. In practice, most browsers can handle PDFs totaling 100-500MB without issues. If you hit a limit, try merging in smaller batches.
Will the merged PDF lose quality?
+
No. PDFDocks uses PDF.js, which preserves the original quality of all pages. The output file maintains the same resolution and visual integrity as the source documents.
Do I need to create an account?
+
No. PDFDocks requires no registration, login, or email. Simply upload your PDFs and start merging immediately.
What formats can I merge?
+
PDFDocks merges PDF files exclusively. If you need to merge other formats (Word documents, images, etc.), you may want to convert them to PDF first using our conversion tools.
