Trim PDF margins by dragging the edges on the preview. Crop all pages or just one. Private and free.
About the Crop PDF Tool
This free online PDF trimmer and cropper lets you trim margins, crop pages, remove black borders, or cut away excess white space from any PDF. It uses a live visual preview — you drag the blue edge handles directly on the page. Everything runs inside your browser, so your file is never uploaded or stored anywhere.
How to Crop a PDF
- Upload your PDF – Drag your file into the upload zone, or click Browse. The first page appears with a blue dashed crop rectangle.
- Visually trim the PDF margins & Adjust the crop area – Drag the blue handles inward to trim margins. You can also enter exact millimeter values below the preview. Works with both mouse and touch.
- Choose which pages to crop – Navigate through pages using the arrows. The "Apply crop to all pages" checkbox lets you crop every page uniformly or just the one you're viewing.
- Crop and download – Click "Crop & Download PDF". The tool processes the file locally and returns a fresh, cropped PDF.
Pro tip: For scanned documents with dark borders, preview both portrait and landscape pages. You may need to crop them separately for a perfect result. The tool remembers your crop values as you navigate, so you can fine‑tune each page individually if needed.
