Crop PDF
Drag the part of the page you want to keep — or let it find the margins for you.

Your files never leave your device.
Drag inside the page to draw the area you want to keep, or drag a corner to adjust it. Arrow keys move it; hold Shift to move faster.
Scanners leave enormous white margins, slide decks come out with letterbox bars, and a page meant for A4 rarely fits the screen you are reading it on. Drag the area worth keeping and the rest goes away. There is also a button that finds the margins for you, which is usually all a scan needs.
Other PDF sites upload your document to a server, then cap how many files you can process or ask you to pay. This one does the work on your own device in plain JavaScript — nothing is transmitted, nothing is stored, and there is no daily limit. Use a tool once and it keeps working with no connection at all afterwards.
Usually only a little. Cropping sets the visible window of each page rather than deleting what falls outside it, so the text and images are still in the file. That is what makes it safe and instant — but if you need a smaller file, run the result through the Compress tool.
Yes. The content outside the crop is hidden, not removed, so a later crop back to the full page brings it into view again. Keep the original anyway if it matters.
It renders the page and looks for the outermost pixels that are not close to white, then leaves a small breathing space around them. On a clean scan it lands very close to the text block. On a page with a coloured background it will find nothing to trim, and says so.
Yes — set it to “This page only”, crop it, download, and repeat. For a single shape applied everywhere, which is what a scanned book needs, leave it on every page.
Yes. The area you drag is interpreted in the orientation you are looking at, including pages that carry a rotation flag or whose box does not start at zero, so the crop lands where you drew it.
Yes, completely — no account, no limits, and nothing added to your document.
