Merge PDF files online — without uploading them
Combine several PDFs into a single file. Drag them in, put them in the right order and download the merged document in seconds.
Your files are merged on your own computer, inside the browser — they never pass through a server. No watermark on the result.
How to merge PDF files into one
Drag your PDFs into the drop area, or click "Select files". Each file appears in a list where you can move it up or down to set the final order. When the order is right, click "Merge and download" and you get one PDF with every page, in sequence.
Merging is useful whenever a recipient wants a single file: a full court filing with its exhibits, a month of invoices for the accountant, a job application with CV and certificates, or the chapters of a report written by different people.
Combine PDFs without sending them anywhere
Merge, combine, join — whatever you call it, most tools do it by uploading your documents to their servers. RoseLab does the work in your browser tab instead, so contracts, medical records or financial statements stay on your machine. There is nothing to install and no watermark on the merged file.
If one of the PDFs is password-protected, the tool asks for the password and unlocks a copy locally before merging.
Frequently asked questions
How do I combine several PDFs into one file?
Add the files, arrange them with the up and down arrows, and click "Merge and download". The result is a single PDF in the order you chose.
Is it free to merge PDFs?
Yes, the free plan lets you merge a number of files every day. Paid plans remove the daily limit.
Are my files uploaded?
No. Merging happens inside your browser and the files never leave your computer.
Will the merged PDF have a watermark?
No. The merged file contains only your pages.
Can I merge password-protected PDFs?
Yes. You will be asked for the password, and an unlocked copy is created locally before the merge.
