Merge PDF

Combine multiple PDFs into a single file. Preview every page, drag to reorder, rotate or deselect pages you don't want, and export with custom options — all in your browser.

Files never leave your device — processing happens entirely in your browser.

— 01

Drop in any order

Upload files as they come in and reorder visually afterwards — the merge uses the order you see on screen.

— 02

Pick pages, not files

Click a file to expand it. Tap page thumbnails to include or exclude individual pages before merging.

— 03

Rotate on the fly

Hover or tap a page thumbnail and hit the rotate button to fix orientation without leaving the tool.

— 04

Stays on your device

Nothing uploads to a server. All processing runs locally — close the tab and every file is gone.
