Stitch several PDFs into one file — cover letter + CV, or scanned pages that arrived one at a time.
Merge PDF glues a stack of separate PDF files into one, in the order you choose. Add each file, drag them into the sequence you want, and download a single document — no page count limits, no re-scanning, no reordering after the fact. Because everything happens in the browser, sensitive files (contracts, medical records, tax paperwork) never touch a server.
Perfect for job applications (cover letter + CV + portfolio), monthly bookkeeping (invoice + receipt + bank statement), or a scanner that saved every page as its own file. One attachment is easier for the recipient to open, forward and archive than a folder full of loose pages, and the merge preserves the exact layout of each original.
There is no limit on the number of PDF files you can merge. You can combine as many documents as needed.
No, merging PDFs does not affect the quality of any page. All text, images, and formatting remain exactly as they were.
Yes, you can arrange the files in any order before merging them.
Yes, all processing happens in your browser using client-side JavaScript. Your files never leave your device.
Pull out the pages you actually need from a long PDF — one chapter, a single invoice, or every page as its own file.
Shrink a PDF that's too big to email or upload — usually by compressing the embedded images, not the text.
Fix a PDF that opens sideways or upside-down — usually a scanner that grabbed the page the wrong way round.
Turn a PDF back into an editable Word document so you can rewrite a section instead of retyping the whole file.
