Konvizi’s “Merge PDF” tool is free, with no sign-up, no watermark and no file limit. All the processing happens in your browser, on your device: your files are never uploaded to a server, which makes it suitable for personal and confidential documents.
Drag your PDF files into the area above or click “Choose files”.
Use the arrows to put the documents in the right order, then click “Merge PDFs”.
Your single document is ready in a few seconds, without ever leaving your device.
Merging PDFs means putting the pages of several documents one after another to end up with a single file: a job application, invoices for your accountant, or the scans of one contract. The pages are copied as they are, without recompression: the text stays selectable and the quality does not change.
PDF is the universal document format: it looks the same on every device, keeps its layout and prints without surprises.
A single PDF is far more practical than ten separate photos for sending an application, a supporting document or scanned papers.
Contracts, payslips, bank statements, tax returns: PDFs often hold sensitive information. With Konvizi they never leave your device, are stored nowhere and read by nobody. Most PDF tools copy pages without recompressing them: selectable text, links and quality are preserved.
Your files never leave your device. No upload, no storage.
No upload and no queue: the conversion starts right away.
As many files as you like, with no imposed size limit.
No sign-up, no watermark, no subscription.

Yes, completely. No sign-up, no watermark, and no maximum number of files.
No. Everything happens in your browser, on your device. Your files are never sent over the internet: nobody but you can see them.
In the order of the list. Use the arrows to move a document up or down before merging. The pages are copied as they are, with no loss of quality.
Konvizi imposes no limit. The only constraint is your device’s memory: very large documents can take a little patience on a phone. Password-protected PDFs cannot be merged.
Open your browser’s developer tools (F12 key), go to the “Network” tab and run a conversion: no request carries your file. The site also enforces a security rule (Content-Security-Policy) that forbids the browser from contacting any site other than konvizi.com, and konvizi.com is a static site with no service able to receive files.
Yes. Konvizi works in the browser of your phone or tablet (Safari, Chrome…) just like on a computer, with no app to install. Very large files are processed faster on a computer, which has more memory.
