Free Online PDF Cropper
SmarterSources's Crop PDF tool lets you visually crop any page in a PDF document. Whether you need to trim wide margins for printing, remove whitespace from scanned documents, or cut out a specific region of a page, this tool gives you full visual control with a drag-and-drop crop box. Everything runs directly in your browser — no uploads, no server processing.
How It Works
Upload your PDF and every page is rendered as a visual thumbnail. Click on any page to see a full-size preview with an interactive crop box. Drag the corner or edge handles to define exactly which area to keep. The crop dimensions are shown in real time so you know the exact size. You can apply the same crop to multiple pages at once, or set different crop regions for each page individually.
Lossless Cropping
Cropping a PDF page sets the CropBox metadata without re-encoding any content. The text, images, fonts, and formatting remain completely untouched — only the visible boundary changes. This means you get the exact same quality as the original with zero degradation. The content outside the crop area is hidden but still present in the file.
Common Use Cases
Scanned documents often have wide white margins that waste space when printing. Presentations exported to PDF may include slide borders you want to remove. Academic papers and reports sometimes need cropping to fit specific page dimensions. Legal documents may need margins trimmed before binding. This tool handles all of these scenarios with precise visual control.
Privacy Guarantee
Your PDF never leaves your device. All page rendering, cropping, and PDF generation happens locally in your browser using client-side JavaScript. No files are uploaded to any server, making this the most private PDF cropper available online.
Frequently Asked Questions
How do I crop a PDF page?
Upload your PDF to the tool. Click on a page to see a full-size preview with a crop box. Drag the handles or edges to define your crop area. Click Save Cropped PDF to download the result.
Can I crop different areas on different pages?
Yes. Click on each page individually to set a different crop area. Each page stores its own crop region independently. You can also apply the same crop to multiple pages at once using the Apply to All Selected button.
Does cropping a PDF reduce quality?
No. Cropping sets the CropBox metadata on the page without re-encoding any content. The text, images, fonts, and formatting remain completely untouched. The hidden content outside the crop area is still in the file but not visible in most PDF viewers.
Can I remove white margins from a PDF?
Yes. Upload your PDF, click on the page, and drag the crop handles inward to exclude the white margins. The crop preview shows you exactly what the final result will look like before you save.
Are my files uploaded to a server?
No. All processing runs 100% in your browser using JavaScript. Your PDF never leaves your device. The cropped file is generated locally and downloaded directly to your computer.
