Free Online PDF Vertical Combiner - Combine PDF into One Long Page
As someone who frequently handles fragmented documents, I highly recommend this free online PDF vertical combiner.
It seamlessly combines multiple PDF pages vertically from top to bottom into a single continuous scrolling page. What makes it incredibly powerful are the advanced customization options. You can retain the native PDF format for searchable text or toggle the 'Convert to Scanned PDF' feature to adjust the page width (e.g., 1600 px) and image quality (e.g., 86%). Furthermore, the tool allows you to add custom borders—you can specify the thickness (like 2 mm), pick a color, and choose specific placements (such as the bottom edge) to neatly divide your combined pages.
Your data security is guaranteed. This tool runs 100% locally in your browser—no server uploads, no registration, and no login required.
