Merging PDF files with LocalPDFs is straightforward and completely private. Start by dragging and dropping your PDF files into the upload area, or click to select them from your device. You can upload up to 10 files, with a total size limit of 10 MB and a maximum of 500 pages across all documents.
Once the files are uploaded, you can reorder them by dragging each file up or down – the order in the list determines the final page order. When you’re ready, click the “Merge PDFs” button. The tool combines all pages locally inside your browser, without sending any data to a server. The merged PDF is then available for immediate download.
No uploads, no servers, no waiting – your documents never leave your device. This means your sensitive information stays private, and you can use the tool even without an internet connection after the page has loaded.
Is it safe to merge PDFs online with LocalPDFs?

What is the maximum file size or number of pages?
Currently we support up to 10 MB and up to 500 pages per file.
Can I merge more than two PDF files?
Absolutely. You can select and merge up to 10 PDF files.
Will the merged PDF preserve my original formatting?
Yes. The tool combines pages exactly as they appear in each source file – text, images, fonts, and layout remain unchanged.
Do I need to create an account?
No account, no sign‑up, no email required. Use the tool immediately.
What happens to my files after merging?
Nothing – because they never leave your computer. Once you close the browser tab, all data is gone.
