Free tool · combine in any order
Merge PDF files
Join certificates, bills, scanned pages and photos into a single PDF. Drag the thumbnails into the right order, remove anything you don’t need, and download one clean file. Merging happens in your browser, so your documents are never uploaded.

Is there a limit on how many PDFs I can merge?
No fixed limit. Each file can be up to 100 MB; the practical limit is your device’s memory, so very large batches work best on a computer.
Are my files uploaded to a server?
No. The PDFs are combined by your browser. Nothing is sent to QRScanKaro, which keeps personal documents private.
Can I merge photos with PDFs?
Yes. JPG, PNG, WebP and iPhone HEIC photos are added as A4 pages in the position you place them.
Will the quality of my PDFs change?
No. Pages are copied as they are, so text stays selectable and images keep their quality.
Why does one of my files fail to add?
It is probably password-protected or damaged. Remove the password by saving a copy without it, then add the copy.
