## What does cropping a PDF do?

Cropping sets a visible area on each page and hides everything outside it — useful for trimming wide margins, removing headers or footers, or zooming in on the content that matters. The page content is preserved; only the displayed and printed area changes.

## How it works here

The first page is rendered as a preview; you drag a box to choose the crop area, and that same area is applied to every page using its crop box. Everything runs in your browser with pdf-lib — your file is never uploaded.

## When to crop a PDF

Remove large white margins to fit more on screen, trim a scanned page down to the document, focus a handout on one figure, or standardise pages before merging or printing. It is a quick way to tidy up a PDF without an editor.

## Cropping vs deleting content

Cropping changes the visible crop box but does not delete the underlying content — a viewer that ignores the crop box could still reveal trimmed areas. For removing sensitive content permanently, redact or rebuild the page rather than crop. Works best on unrotated pages.

## How to

1. Choose your PDF — the first page is shown as a preview, never uploaded.
2. Drag the box to set the crop area applied to every page.
3. Click Crop & download to get the cropped PDF.

## FAQ

**Is my PDF uploaded?**

No. The crop is applied in your browser with pdf-lib, so your file never leaves your device.

**Does the crop apply to all pages?**

Yes. The area you select on the preview is applied to every page using its crop box.

**Does cropping delete the trimmed content?**

No. Cropping hides content outside the crop box but does not remove it. To remove sensitive content permanently, redact or rebuild the page instead.

**Why does my cropped page look off?**

Cropping works best on unrotated pages. If a page has a rotation set, the crop area may not line up as expected.

**Is it free?**

Yes, completely free — no sign-up and no watermark.

**Is my data private?**

Yes — this tool runs entirely in your browser. Your files and text are never uploaded.
