Combine PDFs without handing them to a stranger
Merging PDFs is one of the most common document jobs there is, and almost every free tool for it works the same way: you upload your files to their server. For a contract, a set of payslips or medical records, that is exactly what you do not want. This merger is different. It combines your PDFs entirely inside your browser, so the files never leave your device, and it is still free with no signup and no watermark.
How to merge PDFs
- Add your files: drop in two or more PDFs, or click to choose them.
- Set the order: use the arrows to arrange the files exactly how you want them stacked.
- Merge and download: you get a single combined PDF, saved straight to your device.
Why in-browser matters here
When a tool processes your PDF on its server, your document is uploaded, sits in a queue, and depends entirely on that company's promises about deletion and privacy. Because this tool does the work locally, there is nothing to upload and nothing to trust: the merge happens on your own machine using a built-in PDF library. That also means it works offline once the page has loaded, and there is no file-size cap beyond your device's own memory.
Part of a full PDF toolkit
Once your PDFs are combined you may want to tidy the result: reorder or delete pages, add page numbers, or compress it. Every PDF tool on Etoolio follows the same privacy-first approach, so you can do the whole job without a single upload. Merging is free, unlimited and leaves no watermark on your file.
