PaperHeroHow it works

- Click "Merge PDF" and download the result.
Merge PDF files - free, online and without a sign-up
Job applications, tax receipts, contract pages: many places want exactly one PDF file, not a loose collection of separate documents. To merge PDF files, just pick them and set the order - whether you combine two PDFs or join twenty documents into one file. Free, no sign-up, no watermark, no installation: it works right on this page, on your computer and on your phone.
Combine PDF files without uploading them
Unlike most online services for merging PDFs, your files never leave your computer. The merging happens entirely in your browser - payslips, contracts or medical letters stay on your device. That makes the tool safe even for confidential paperwork, and it stays fast even with large files because there is no upload.
And where does the finished PDF go?
PaperHero stores it encrypted in Germany, reads the text and finds it again when you need it. 30 days for €1, then €5.99 per month - cancel monthly.
Frequently asked questions
Are my files uploaded?
No. Merging happens entirely in your browser. The files never leave your computer, and once you close the tab nothing remains.
Is there a limit on count or size?
No fixed limit - the boundary is your device's memory. Ordinary documents with a few hundred pages are no problem.
Do bookmarks and links survive?
Page content is preserved completely. Document-wide extras such as bookmarks can get lost during merging.
