Trim PDF margins, free
Slides exported with ocean-wide white borders, scans swimming in empty space — dead margins waste screen, paper, and attention. Set four margins in points and preview the resulting page size live, apply to the whole file or just a range, and download tighter pages. Content is never re-rendered or degraded; the crop simply redefines each page's visible frame.
How to crop PDF margins
- 1Drop your PDF and check its page size in points.
- 2Set four margins watching the live new-size preview. Start with 36pt all around.
- 3Hit Crop pages and download. Choose all pages or a range like 1-3, 5.
Tight but safe
36pt ≈ half an inch
A point is 1/72 inch — 36pt trims a comfortable half-inch border without threatening content.
Range-mode mixed files
Title pages often need different margins than body pages — crop them as separate ranges.
Nothing is deleted
Cropping redefines the visible frame; the underlying content stream stays intact in the file.
Frequently asked questions
How do I crop white space from a PDF?
Drop it above, set top/bottom/left/right margins in points, hit Crop pages. The preview shows the new size before you commit.
What are points?
PDF's unit — 72 points per inch. So 36pt is half an inch, 72pt a full inch of margin.
Can I crop only some pages?
Yes — switch to Range mode and type pages like 1-3, 5. The rest stay exactly as they were.
Does cropping lower quality?
No. It only changes each page's visible frame — no pixels are re-rendered.
Are my files uploaded?
Never. Cropping runs entirely in your browser.
