How to merge PDF files

1

Select your PDFs

Drop your PDF files into the merge area or pick them from your device. They're read locally — no files are uploaded to any server.

2

Arrange the order

Drag and drop the file rows to set the exact page order you want in the final merged document. Reorder until it's perfect.

3

Click Merge

Hit the merge button. Your PDFs are combined in your browser's memory — the process takes seconds even for large files.

4

Download the result

Save the single merged PDF to your device. No watermark, no page limit, no sign-up required — just instant results.

about this tool

Merge PDF without giving up your privacy

Online tools often ask you to upload your files before processing them. For anything sensitive — contracts, statements, personal documents — that's a real privacy concern. This tool takes a different route: everything runs entirely in your browser. Your files are opened locally, processed in your device's memory, and handed back to you. No copy is ever transmitted to a server, which means it works offline too.

Privacy by design. This tool loads once and runs entirely in your browser tab. Close the tab and nothing remains. No cookies, no tracking, no server — just the utility you need, instantly.

Merge PDF — frequently asked questions

No. The merge happens entirely inside your browser. Your PDFs are read locally, combined in your device's memory, and the result is handed back as a download. Nothing is ever sent anywhere.
There's no fixed limit. Because everything runs locally, the practical ceiling is your device's memory. Most users merge anywhere from 2 to 50+ files without issues.
No. The merge copies each page exactly as it appears in the source files. Text stays selectable, images keep their resolution, and form fields and links are preserved.
Yes. After adding your files, drag any row up or down to change the order. The final PDF follows the list order, top to bottom.
No. There's no sign-up, no email collection, no paywall. Just open the tool, merge your files, and download.
