Merge & Combine PDF Files Online — Lossless, Private
Combine two or more PDF documents into a single file without re-encoding. Because the merger works directly on the raw PDF page streams, your text, images, fonts, and metadata stay exactly as they were — no quality loss, no watermarks.
How it works (lossless, client-side)
- Drop or select multiple PDFs — they appear as an ordered list.
- Drag the items (or use the arrows) to set the merge order.
- Click Merge — the files are combined locally and downloaded instantly.
Frequently asked questions
Is the merge lossless?
Yes. The merger copies full page objects (including their fonts, images, and content streams) with pdf-lib, so text, images, fonts, and metadata are preserved exactly — no re-encoding.
Are my PDFs uploaded anywhere?
No. Merging happens entirely in your browser. Your files never touch a server.
How many PDFs can I merge?
As many as your device memory allows. Reorder them by dragging before merging.
