Merging PDFs is one of the most common document chores: stitching a cover letter to a résumé, combining scanned receipts, or assembling chapters into one report. ToolOrbit’s Merge PDF tool does it entirely in your browser using the pdf-lib library, so your files never get uploaded to a server.
How merging works
The tool reads each PDF you add, copies every page into a fresh document in the order you choose, and saves the result. Because pages are copied rather than re-rendered, text stays selectable and quality is untouched.
How to merge PDFs
- Drop in or select two or more PDF files.
- Use the up and down controls to arrange the order.
- Click Merge to build the combined document.
- The merged PDF downloads automatically.
Order matters: the files merge top-to-bottom in the list, so arrange them before clicking Merge.
Why do it in the browser
Most online PDF mergers upload your documents to their servers. For contracts, invoices, or anything confidential, that is a real privacy risk. ToolOrbit keeps everything local, so the only place your PDFs exist is your own device.
