Is this PDF Merger safe to use?

Yes, it is 100% secure. Unlike other websites, we do not upload your files to a server. All merging happens locally in your browser using JavaScript, so your data never leaves your device.

Is there a limit on file size?

There are no artificial limits on file size or the number of files. However, because the processing happens on your device, very old computers might slow down with extremely large files (500MB+).

Can I reorder the PDF pages?

Yes. Once you upload your files, you can simply drag and drop them to change the order before merging.

Why Use Our PDF Combiner?

While there are many tools available, most require you to upload your sensitive documents to a remote cloud server. This poses a privacy risk. We do things differently:

100% Client-Side Security: We use advanced browser technology to merge your files on your own device. Your contracts, bank statements, and ID cards are never uploaded to our servers.
No Limits: Merge as many files as you want. We don't cap your usage or watermark your documents.
Drag & Drop Ordering: Get your document structure perfect. Simply drag the files in the list to rearrange the page order before merging.
Fast & Free: No software installation, no registration, and no waiting for uploads.

Common Use Cases

Job Applications: Merge your Resume, Cover Letter, and Portfolio into one file so recruiters don't miss anything.
Invoices & Receipts: Combine monthly receipts into one PDF for easier accounting and tax filing.
E-Books & Reports: Join separate chapters or project sections into a final polished manuscript.
