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.
Cropping only changes the visible page boundary; the underlying text remains selectable and searchable, unlike cropping a rasterised image of the page.
Apply one crop setting across the whole document, or adjust individual pages when scanned margins are inconsistent from page to page.
Wide scanner borders, printer crop marks or excess white space can be trimmed away, tidying up a document before sharing or printing.
The crop box can be repositioned and previewed as many times as needed before the final crop is applied and downloaded.
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.
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.
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.
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.
Cropping changes the visible page box rather than deleting content, so size stays similar — combine it with the PDF Compressor for a smaller file.
