PDF cropping adjusts the visible area (crop box) of each page. Content outside the cropped area won't be visible. The original file on your device is never modified â you're downloading a new cropped version.
No. Cropping only changes the visible boundary â it does not re-render, compress, or alter content within the crop area. Quality of text and images inside the cropped region remains exactly as in the original.
Yes. Use the "Apply Crop To" section and choose "Current Page Only" or "Custom Range" to crop just the pages you need â all other pages are left completely untouched in the downloaded file.
Yes. When "Current Page Only" or "Custom Range" is selected, a checkbox appears â "Download only the cropped page(s)." Enable it and your download will contain just the cropped pages as a smaller, standalone PDF, excluding everything else.
Yes. Click "đ Copy Cropped Image" below the preview â it copies just the selected crop region of the current page to your clipboard as an image, ready to paste directly into any app with Ctrl/Cmd+V. If your browser doesn't support clipboard image copying, it automatically downloads the image as a PNG file instead.
Never. The entire cropping process runs inside your browser using JavaScript and PDF-lib. Your file is never sent to any server. Once you close the tab, no trace of your document remains anywhere outside your own device.
Yes. Simply click and drag directly on the preview image to visually select the area you want to keep. The Top, Bottom, Left, and Right margin values update automatically based on your selection â you can also fine-tune them manually afterward.
