Crop PDF

Crop PDF pages visually to remove white margins, scan borders or unwanted edges. Apply one crop to every page or crop pages individually, free.

Crop PDF lets you trim the visible page area of a PDF by dragging a crop box over each page, removing unwanted margins, scanning borders or blank space without altering the actual content inside the crop area. This differs from cropping an image because the underlying text and vector graphics remain fully intact and selectable — only the visible page boundary changes.

It is especially useful for cleaning up scanned documents that have wide, uneven margins, removing printer registration marks or crop guides that got included in an export, or tightening the page size of a PDF before merging it with other pages that use a smaller page format. The crop is applied locally in your browser, and you can preview the result on each page before saving the trimmed document.

How to use the Crop PDF

  1. Upload the PDF you want to crop.
  2. Drag the crop box handles on the page preview to select the area you want to keep.
  3. Apply the same crop to all pages, or adjust it individually per page if margins vary.
  4. Preview the cropped result to confirm no content has been cut off.
  5. Click apply to crop the document.
  6. Download the cropped PDF.

Why use this tool

Text and graphics stay intact

Cropping only changes the visible page boundary; the underlying text remains selectable and searchable, unlike cropping a rasterised image of the page.

Per-page or uniform cropping

Apply one crop setting across the whole document, or adjust individual pages when scanned margins are inconsistent from page to page.

Removes unwanted margins and marks

Wide scanner borders, printer crop marks or excess white space can be trimmed away, tidying up a document before sharing or printing.

Non-destructive preview

The crop box can be repositioned and previewed as many times as needed before the final crop is applied and downloaded.

Common use cases

How cropping differs from editing content

Cropping a PDF changes only the page's visible boundary box, similar to a mat around a picture frame — the text and graphics outside the crop are hidden from view but the file itself is not permanently altered at the content level in the same destructive way an image crop is.

Uniform versus per-page cropping

When every page shares the same layout, applying one crop setting to the whole document is fastest. Scanned documents often have margins that drift slightly from page to page, in which case adjusting the crop individually per page gives a cleaner, more consistent result.

Common reasons to crop a PDF

Typical uses include trimming a scanner's wide white borders, removing crop marks left by a commercial printer's export settings, and matching page dimensions across documents that will be merged or bound together.

Checking the result before downloading

Always preview each page after cropping, particularly on documents with varying content position, to confirm that no text, numbers or images near the edge have been accidentally hidden by an overly tight crop box.

Frequently asked questions

Does cropping reduce file size?

Cropping changes the visible page box rather than deleting content, so size stays similar — combine it with the PDF Compressor for a smaller file.

Can I crop every page the same way?

Yes. Draw the crop area once and choose 'apply to all pages' so scanned documents get consistent margins throughout.

Is Crop PDF free to use?

Yes. Crop PDF on Klipza is completely free with no account, no subscription and no watermark on your files, and there is no daily usage limit.

Are my files safe when using Crop PDF?

Processing happens locally in your browser wherever technically possible, so your files are not uploaded to a server, stored or shared with third parties.

Does Crop PDF work on mobile phones?

Yes. It is fully responsive and runs in any modern browser on Android, iPhone, iPad, Windows and macOS — nothing to install.
