How to merge PDF files for free

Combining multiple PDF files into one document is easier than you think. You do not need software, an account, or a subscription. On PDFrust you do it for free, directly in your browser.

When do you need to merge PDFs?

You have a quote, attachments, and a cover letter as separate files. Or you scan documents page by page. In all these cases you eventually want one clear PDF document. Merging them on PDFrust takes three steps.

How does it work?

Drag the PDF files onto the page, put them in the right order using the arrows, and click merge. You download the result immediately. Everything happens in your browser: your files are not uploaded to a server and disappear automatically after use.

How many files can I merge?

There is no limit to the number of PDFs you can merge. Since everything is processed locally in your browser, the speed depends on your device. With large files or dozens of pages it takes a little longer.

Is quality preserved?

Yes. Pages are copied unchanged from the source files and joined together. No quality is lost: text stays selectable, images keep their resolution.
