About Merge PDF
Combining PDFs shouldn't require a $20/month Acrobat subscription or a shady desktop install. Filenify's Merge PDF tool stitches any number of PDF files into a single clean document using pdf-lib compiled to WebAssembly, so the whole job runs inside your browser tab. Your files never leave your device — no upload, no queue, no server-side quota. Drag files in from Finder, Explorer, or your Downloads folder, drop them in the order you want, remove any pages you don't need, and hit Merge. The output is a byte-for-byte copy of each source page (fonts, images, bookmarks, form fields, hyperlinks all intact), wrapped into one PDF you can share, print, or upload anywhere.
