How to Merge PDF Files (Free, in Your Browser)
Updated July 12, 2026
Combining several PDFs into a single document is one of the most common PDF jobs — stitching together a report, an application, or a batch of scans. Here’s how to do it for free, in the right order, without uploading your files anywhere.
The quick way
- Open Merge PDF.
- Add your files (drag them in, or click to select several at once).
- Drag to reorder — the order in the list is the order in the final document.
- Click merge and download.
That’s it. With HivePDF the whole thing runs in your browser, so even a stack of confidential files never leaves your device.
Get the order right
The single most common merge mistake is page order. Before you download:
- Arrange the files top-to-bottom in the exact sequence you want.
- If you need to reorder, rotate, or drop individual pages (not whole files), use Organize PDF after merging — it gives you a visual grid of every page.
Merging scans and images too
Your source isn’t always a PDF. To fold images into the merge:
- Convert them first with JPG to PDF — it also takes PNG, HEIC, WebP, BMP, and TIFF, one image per page.
- Then merge the resulting PDF with your others.
This is the reliable way to combine phone photos of a document with a digital PDF into one clean file.
After merging
A couple of common follow-ups:
- Too big to email? Run the merged file through Compress PDF — see our guide on compressing a PDF for email.
- Need to split it back up later? Split PDF breaks a document into parts by range or one file per page.
Why do it in the browser
Merging is simple, but it often involves documents you’d rather not upload — signed forms, IDs, financial statements. A client-side tool keeps them on your machine, works offline, and doesn’t watermark or limit the result. Give it a try with Merge PDF.
