Crop PDF Online

FloxerFile lets you crop the margins of any PDF directly in your browser. Whether you're removing scanner borders, tightening whitespace before printing, or preparing a document for a specific layout, set the exact margin to trim from each side and every page is cropped consistently — no software, no sign-up.

How it works

1. 1

   Upload your PDF

   Drag and drop your PDF or click to browse. Files up to 20 MB are supported.

2. 2

   Set your margins

   Enter the top, bottom, left, and right margins to remove, in points (72 points = 1 inch). Leave a field at 0 to keep that side unchanged.

3. 3

   Crop

   Click Crop PDF. Every page is cropped to the new dimensions on our servers.

4. 4

   Download your cropped PDF

   Download the resulting PDF with the new margins applied to every page.

Features

• Per-side margin control

  Set independent top, bottom, left, and right margins instead of a single uniform crop.

• Applies to every page

  The same margins are trimmed consistently across all pages of the document.

• Content preserved

  Cropping only adjusts the visible page area — text, images, and links are never altered.

• Precise, point-based input

  Margins are entered in PDF points for exact, repeatable results.

• Original content stays in the file

  Cropping moves the PDF's crop box, not the content itself — anything just outside the new visible area is still present in the file, so nothing is destructively cut away.

Supported formats

Output format: .pdf

Frequently asked questions

What unit are the margins in?

Margins are entered in PDF points, the standard unit for PDF page geometry. There are 72 points to an inch, so a 1-inch margin is 72 points.

What happens if I leave a margin empty?

Any margin left empty defaults to 0, meaning that side of the page is left untouched.

Can the margins be too large?

Yes. If the combined margins on an axis are equal to or larger than the page's width or height, there would be nothing left to show, so the tool rejects the request and asks you to use smaller values.

Will cropping change the content of my PDF?

No. Cropping only changes the visible page boundary (the crop box). The underlying content — text, images, and links — is not modified or re-rendered.

Can I crop a password-protected PDF?

No, password-protected PDFs cannot be cropped. Remove the password protection first using your PDF reader, then crop the file.

Does cropping actually delete the cropped-out content?

No. Cropping sets the PDF's crop box — the visible region a reader displays — without touching the underlying page content. Some tools can still read outside that box, so don't rely on this alone to permanently remove sensitive content; use Remove Pages or a proper redaction tool for that.
