Merge PDF Files Online — Combine PDFs Free & Private

Combine multiple PDF files into one in seconds. Uses your browser alone — no uploads, no account, and your documents never leave your device.

Combining multiple PDF files into a single document is essential for creating reports, compiling invoices, or assembling application packages. Most online merge tools upload your files to a server, which raises privacy concerns for sensitive documents.

ConvertCraft merges PDFs entirely in your browser. The tool uses pdf-lib, a JavaScript library that manipulates PDF structures directly in memory without any server round-trip.

To merge PDFs: 1) Open the PDF Split & Merge tool. 2) Drag and drop multiple PDF files. 3) Reorder them by dragging. 4) Click Merge and download the combined document instantly.

You can merge any number of PDF files — the only limit is your browser memory. A typical laptop can comfortably handle merging dozens of files totaling hundreds of megabytes.

The merged PDF preserves all original formatting, bookmarks, and internal links. Page sizes can differ between source files — the tool handles mixed layouts seamlessly.
