🔒 100% private — your PDFs are merged on your device using PDF-lib. Nothing is ever uploaded to a server.

Merge PDF files without uploading anything

This PDF merger combines multiple PDF documents into a single file directly inside your browser tab. There's no upload to a server, which means no waiting, no file-size anxiety about sensitive documents, and no account to create.

How to merge PDFs

Drag and drop your PDF files into the box above, or click to browse.

Reorder files by dragging any row (or its ⠿ handle) — page-count and a live thumbnail preview load automatically. The merge follows the order shown.

Click Merge PDFs and the combined file downloads instantly.

Why merge locally instead of uploading?

Many online PDF mergers upload your files to a remote server for processing, which means your documents leave your device — a real concern for contracts, ID proofs or financial statements. This tool uses PDF-lib running directly in your browser, so the merge happens on your machine and the files never travel anywhere.

Is there a file size or page limit?

You can merge up to 30 PDFs at once. Because everything runs in your browser, very large files depend on your device's available memory rather than a fixed server-side limit.

Does merging affect PDF quality?

No. Pages are copied as-is from each source file, so text, images and formatting stay exactly as they were in the original documents.

Can I merge password-protected PDFs?

Files that are encrypted with a password may need that password removed first, since browser-based processing cannot decrypt protected PDFs without it.

Can I see how many pages each PDF has before merging?

Yes — once a file is added, its page count and a thumbnail of the first page load automatically, so you know exactly what you're combining and in what order.
