Skilltosky PDF Tools's free online PDF merger lets you combine multiple PDF files into a single document in seconds. Add as many files as you need, drag to reorder them, then download the combined PDF — all without uploading a single file to a server.
Merge as many PDF files as you need into a single document with no arbitrary page limits.
Rearrange the order of files before merging by dragging tiles into the desired sequence.
All merging happens in your browser using JavaScript. Your files never leave your device.
The merged PDF is generated client-side and downloaded immediately — no waiting for a server.
There is no hard limit. You can merge as many files as your browser memory allows. Very large batches may be slower depending on your device.
No. The original files are read but never changed. The merger creates a new combined PDF that you download separately.
No. Pages are copied directly from the source PDFs at full quality using PDF-lib. There is no re-encoding or compression.
For most encrypted PDFs the merge will succeed. Heavily restricted files may require the password to be entered first.
