Quick answers

Short, sourced answers to the questions people (and AI assistants) ask most.

What is Crop PDF?
Crop PDF trims the margins of every page by a percentage, hiding unwanted white space or edges without changing the content.
Why does Crop PDF matter?
Pages appear tighter around the content. Because only the crop box changes, no text or images are deleted; a viewer simply shows less margin.
How is Crop PDF calculated?
It sets a smaller crop box on each page - the visible area - trimming the chosen percentage evenly from all four sides, in your browser. The underlying content is untouched, so it is lossless.
What is a good crop pdf?
Cropping changes the visible box, not the page content. Some tools and printers may still honour the full page - check in your target viewer.
What are common crop pdf mistakes?
Cropping too aggressively and clipping real content - preview first.
When should you use the Crop PDF?
Use it to remove wide scanner margins, tighten a document for on-screen reading, or focus each page on its content before printing.

How the Crop PDF works

It sets a smaller crop box on each page - the visible area - trimming the chosen percentage evenly from all four sides, in your browser. The underlying content is untouched, so it is lossless.

What's a typical value?

Cropping changes the visible box, not the page content. Some tools and printers may still honour the full page - check in your target viewer.

Common mistakes to avoid

  • Cropping too aggressively and clipping real content - preview first.
  • Expecting the file size to drop - cropping hides, it does not delete.
  • Assuming every viewer respects the crop box identically.

Keywords: crop, pdf, margins, trim, edges.

I built a free crop pdf that works instantly in the browser — no signup, no ads in your face
Body
Hey r/[subreddit],

I kept needing a quick crop pdf and most options online were slow or behind paywalls, so I built one that:

• Runs 100% in your browser (your data never leaves your device)
• No signup, no email wall, no popups
• Loads in under a second on mobile

It covers the standard crop pdf use cases (crop, pdf, margins, trim) and links out to the formula + worked examples if you want to learn the math.
