How to Crop a PDF
Online for Free
Thick white margins, a header you don't want, or a scan with junk around the edges? Here's how to crop any PDF by dragging a box — losslessly, privately, with no upload.
Cropping a PDF is about focus. Slide exports come with huge empty borders, scans capture the desk around the paper, and reports repeat the same header on every page. Cropping trims all of that so the content fills the page and looks clean on screens and in print.
Unlike editing an image, cropping a PDF the right way is lossless — you're changing the page boundary, not re-rendering the content. Here's how to do it for free in your browser.

Open Crop PDF & StartWhat "Cropping" a PDF Actually Does
Every PDF page has a CropBox — the rectangle that defines the visible area. Cropping simply shrinks that rectangle. The underlying text and graphics aren't touched or re-compressed, which is why a properly cropped PDF stays perfectly sharp at any zoom level. (This is different from cropping a JPG, which permanently throws away pixels.)
Step-by-Step: Crop a PDF
Using the free Raha Crop PDF tool:
1. Upload your PDF
Drag in your file. The first page opens with an adjustable crop box already on it. Nothing is uploaded.
2. Set the crop area
Drag the box to move it, or drag any corner/edge handle to resize. The area outside the box is shaded so you can see exactly what will be removed. Quick presets ("Full page", "Trim margins", "Center 80%") give you a fast starting point.
3. Apply to all pages (or just one)
Keep Apply to all pages on to crop the whole document the same way, or turn it off to crop only the current page.
4. Download
Click Crop & Download to save your trimmed PDF — vector-sharp, no watermark.
Great Uses for Cropping
- Slide decks: remove the wide letterbox borders from exported slides.
- Scans: trim the desk, shadows, or black edges around a scanned page.
- Reading on phones: cut margins so text fills a small screen.
- Focusing on a chart or table from a busy report.
