Is this PDF merger really free?

Yes, completely free with no limits, no watermarks, and no signup required. You can merge as many PDFs as you want, as many times as you need.

Are my files uploaded to a server?

No. Everything is processed directly in your browser using JavaScript. Your files never leave your device — no data is sent to any server. This makes it faster and more private than other PDF tools.

What file types can I merge?

You can merge PDF files, JPG images, and PNG images. Images are automatically converted to PDF pages before merging. This means you can combine documents and photos into a single PDF.

Is there a file size limit?

There is no hard limit, but we recommend keeping the total size under 100 MB for best performance. Since everything runs in your browser, very large files may slow down processing depending on your device.

Can I reorder files before merging?

Yes. Drag and drop the files into your desired order, or use the arrow buttons to move files up and down. You can also remove individual files from the list before merging.

Does this work on mobile?

Yes. The tool is fully responsive and works on phones and tablets. On mobile, use the arrow buttons to reorder files and the file picker to add documents.

Merge PDFs Without Uploading Your Files

Most online PDF merging tools require you to upload your documents to a remote server. Your files travel across the internet, sit on someone else's infrastructure, and you have to trust that they're deleted afterward. This tool works differently — everything runs directly in your web browser. Your PDFs and images are processed on your device using JavaScript, and no data is ever sent to a server.

This means faster processing (no upload/download wait), complete privacy (your files stay on your machine), and it works offline once the page has loaded. Whether you're combining contracts, merging scanned documents, or assembling a report from multiple sources, your data stays yours.

Combine PDFs and Images in One Step

This tool accepts both PDF files and images (JPG, PNG). When you add an image, it's automatically converted to a PDF page at the original image resolution before merging. This makes it easy to combine scanned photos, screenshots, or receipts with existing PDF documents into a single file — no separate conversion step needed.

How the Merge Works

The merge process uses pdf-lib, an open-source JavaScript library for PDF manipulation. For each file you add, the tool reads the PDF structure and copies every page into a new combined document. The original formatting, fonts, images, and links in your PDFs are preserved exactly as they are. The output is a standard PDF file that works in any PDF viewer.

When to Use a PDF Merger

Combining contracts or legal documents — merge multiple agreements, addendums, or annexes into a single file for signing or filing.
Assembling reports — combine a cover page, charts, data tables, and appendices from different sources.
Organizing scanned documents — merge individually scanned pages into one multi-page PDF.
Creating portfolios — combine work samples, certificates, or reference letters into a single document.
Submitting applications — merge forms, identity documents, and supporting materials into one file for upload.
