PDF Marge tools
Combine multiple PDF files in any order — everything runs in your browser, nothing gets uploaded
or drag and drop files here
⚠️ Your files are never uploaded to any server — merging happens entirely inside your browser (device). For large PDFs (100+ pages), thumbnail generation may take a few seconds.
About This Tool
This PDF Merge Tool is built for anyone who needs to combine multiple PDF files into a single file — without installing any software or uploading files to a server. Most online PDF mergers send your files to their server, which creates a risk for private or sensitive documents. This tool doesn't do that.
The entire merging process happens right inside your browser (via JavaScript) — your files never leave your device. As soon as you upload your PDFs, you'll see page-by-page thumbnails, which you can drag to arrange in whatever order you want, and remove any page you don't need — all before the final merge.
How to Use This Tool
- Select your PDF files — click "Select PDF Files" or drag and drop files directly into the drop area. You can select multiple PDFs at once.
- Set the order — a thumbnail preview appears for every page. Drag the thumbnails to arrange them in the order you want for the final PDF.
- Remove pages if needed — click the ✕ button on any thumbnail to remove that page.
- Click "Merge PDF" — merging starts immediately.
- Download the result — once complete, click "Download merged.pdf" to save the final file.
Note: For large PDFs (100+ pages), thumbnail previews may take a few seconds to generate — this is normal, and your files stay safe throughout.
