Open a document, click the pages that should go — or type them as ranges — and download the file without them. Everything happens in this browser — the file itself never leaves your device.
Step by step
What it does
Every page is shown as a thumbnail. Click the ones that should go, or type them as ranges when there are too many to click, and download the file without them. Nothing is removed until you download, so you can change your mind about a page right up to the last moment.
This tool runs entirely inside your browser tab. The file never leaves your machine, there is nothing to sign up for, and nothing you download carries a watermark.
