Alternate pages from two PDFs into one document. Perfect for combining front and back scans of double-sided documents. No upload, no account.
Double-sided document scanning creates a classic problem. When you scan a stack of papers front-side first through an automatic document feeder, you get all the odd-numbered pages in order. When you flip the stack and scan again, you get all the even-numbered pages in reverse order. The result is two PDFs: one with pages 1, 3, 5, 7... and another with pages 8, 6, 4, 2... The ability to interleave pdf pages free online no upload solves this by alternating pages from both PDFs into the correct reading sequence.
iFixMyPDF's Interleave PDFs tool takes two PDFs and creates a single output document where pages alternate: page 1 from PDF 1, page 1 from PDF 2, page 2 from PDF 1, page 2 from PDF 2, and so on. This is the exact workflow needed to reconstruct a properly-ordered double-sided scan. Everything happens in your browser with no upload required.
Double-sided scan tip: If your second PDF has pages in reverse order (which happens when scanning the back side of a stack), use the Reverse PDF tool on it first to correct the order, then interleave with the first PDF.
The ability to alternate pdf pages two documents browser-side means both your PDFs are processed entirely within your browser. For scanned documents - which often contain personal identification, contracts, financial records, or medical information - avoiding cloud upload is a genuine privacy advantage.
