Merge PDF files
Combine several PDF files into one.
Open a PDF and every page appears as a thumbnail, so you can see at a glance which one came in sideways. Turn a single page with the arrows on its corner, or select several — by clicking, by typing a range, or by asking for every landscape page — and turn them together. The turn is written into the file as the orientation of the page itself, so nothing is re-drawn and nothing loses quality.
What it does
This tool runs entirely inside your browser tab. The file never leaves your machine, using it needs no sign-up, downloading needs only a free account, and nothing you download carries a watermark.
Step by step
Questions
No. The page is not re-drawn — the turn is written into the file as the orientation of the page itself, so text stays text and a scan keeps every pixel it arrived with. Pages you leave alone are not touched at all.
