Merge PDF

Merge PDF combines several PDF files into one continuous document in the exact order you specify, concatenating all pages so a stack of separate reports, scans, chapters, or invoices becomes a single file that's easier to share, print, and archive. You control sequencing by ordering the inputs before merging, so the combined document reads top to bottom in your intended arrangement.

Under the hood, merging copies the page objects from each source PDF into a new document, preserving each page's original dimensions, orientation, and embedded fonts and images rather than re-rendering or flattening the content. Because pages are carried over as-is, text stays selectable and searchable and vector graphics keep their crispness — the merge is lossless for the page content itself.

Common scenarios include assembling a signed contract from separately signed pages, bundling monthly statements into a yearly file, combining a cover letter with a resume and portfolio, or stitching scanned chapters into one book. This tool sits naturally alongside other PDF workflows such as splitting, reordering, and compressing — merge first, then trim or shrink the result if needed.

Practical tips: name or arrange your inputs so the order is unambiguous before you merge, mind that mixed page sizes (for example A4 and US Letter) will retain their individual dimensions in the output, and run the result through a compressor if combining many image-heavy scans produces a large file. If a source PDF is password-protected, remove its restrictions first so its pages can be copied into the merged document.
