How to crop a PDF in 3 steps

1. Upload your PDF
Drag and drop a PDF file into the upload zone, or click “Choose File”. The first page appears as a preview.
2. Drag the crop rectangle
Drag the box on the preview to select the area you want to keep. Move it around, or drag a corner dot to resize it — the darkened area outside the box is what gets trimmed.
3. Crop & download
Optionally enter a page range (for example “1-3, 5”) or leave it empty to crop every page. Click “Crop & Download” — your cropped PDF is ready instantly.

Why crop a PDF?

Scanned documents and exported PDFs often come with thick white margins, scanner shadows, or unwanted headers and footers. Cropping trims those edges away so the content fills the page — which makes documents easier to read on phones, cleaner when printed, and more professional when shared. Students cropping scanned book pages, offices cleaning up scanned contracts, and anyone preparing slides from PDF pages all use cropping daily.

Cropping is also the fastest way to fix a bad scan. If your scanner captured two book pages side by side, or left a dark border around the page, a quick crop removes the distraction without any image editing software. Because the crop is applied as a view setting on each page, the original file size barely changes and the whole operation takes seconds — even on long documents with dozens of pages.

Why use PDFLite's free PDF cropper?

✂️ Visual crop editor

See exactly what you keep. Drag the rectangle on a live preview of your page — no guessing numbers, no trial and error with margins.

📄 All pages or a range

Apply one crop area to the whole document, or target specific pages with ranges like “2, 5-7”. Perfect for mixed documents where only some pages need trimming.

🎯 No quality loss

Cropping only changes each page's visible area — your text and images are never re-rendered, so quality stays pixel-perfect.

🔒 Private by design

Cropping happens entirely in your browser. Your documents are never uploaded, stored or seen by anyone — not even us.

Frequently asked questions

How do I crop a PDF online for free?

Upload your PDF to the crop tool above, then drag the crop rectangle on the page preview to select the area you want to keep. Click “Crop & Download” — your cropped PDF downloads instantly, no account needed.

Will cropping reduce my PDF quality?

No. Cropping only changes the visible area of each page (the PDF CropBox) — the content is not re-rendered, so text and images keep their original quality.

Can I crop only some pages of my PDF?

Yes. Enter a page range like “1-3, 5” to crop only those pages. Leave the field empty to crop every page with the same crop area.

Does cropping permanently delete content outside the crop area?

Cropping hides the area outside the rectangle — virtually all PDF viewers respect the crop and will not show it. The underlying content technically remains in the file, so for truly removing sensitive content use redaction instead.

Are my files uploaded anywhere when I crop a PDF?

No. Cropping happens entirely in your browser with client-side technology. Your files never leave your device.

Can I crop a scanned PDF?

Yes. Scanned PDFs are just images inside a PDF wrapper, and cropping works the same way — drag the rectangle over the scanned page preview and the dark scanner borders or extra margins are trimmed away. The scan itself is not re-processed, so the image quality stays exactly as scanned.
