Merge PDF Files Online
Combine multiple PDF files into a single document in seconds — directly in your browser, with drag-and-drop ordering and nothing sent to any server.
How It Works
ClearConvert uses pdf-lib, a JavaScript library that runs entirely on your device, to copy pages from each of your PDFs and assemble them into a single output file. No server is involved at any point — the merged PDF is generated locally and downloaded directly to your device.
Add as many files as you need, drag them into the order you want, and click Convert. The result is a single PDF containing all pages from all input files, in the exact sequence you specified.
Drag-and-Drop Reordering
When you add multiple files, they appear in a sortable list. You can drag any file up or down to change the order before merging. This means you can combine a cover page, a main document, and appendices in whatever sequence makes sense — without needing to rename files or rely on alphabetical ordering.
Your files never leave your device. No PDF is uploaded to any server. Everything is processed locally in your browser.
How many files can I merge?
There is no fixed limit on the number of files. You can add as many PDFs as your browser can handle in memory. For most use cases — contracts, reports, presentations — combining dozens of files works without issue.
Will the quality of my PDFs be affected?
No. ClearConvert copies pages directly from your source PDFs without re-rendering or compressing them. The output quality is identical to the input — fonts, images, vector graphics, and formatting are all preserved exactly as they appear in the original files.
Is this free?
Yes, completely free with no account, no watermarks, and no file count limits. Open the tool and start merging immediately.
