Crop PDF

About crop PDF pages

Trim an equal margin from selected PDF pages. Tighten excess border space around a scan or make the same margin adjustment throughout a selected set of pages.

This tool is designed for a focused file task, not a broad document-editing workflow. Check the input and output summary above, then use the page preview and settings to describe exactly the copy you want to download.

How PDFolio helps you crop PDF pages

Enter a margin in PDF points, then select the pages that need a tighter visible page area. One PDF point is 1/72 of an inch, so begin with a modest number if content sits close to an edge.

Before you process the file, take a moment to check the file list, selected pages, and visible settings. PDFolio creates a new result rather than modifying the source file, which lets you keep the original document as a reference or make another version with different settings.

Before you download

Cropping changes the visible crop box in the exported file. It is not a redaction feature and does not permanently erase content outside the visible area. A value that would leave no usable page area is rejected.

Use clear source filenames and confirm the exact output you need before processing. That small check is especially helpful for sensitive files, repeated versions, or documents with similar page names. The settings shown beside the workspace are the settings applied to the downloaded result.

Choose a unique output filename in your downloads folder if you are keeping several versions of the same document. The original file is never replaced automatically. If you plan to send the result, use the downloaded copy rather than a browser preview, and confirm its page count or file size after processing. This helps prevent confusion between a working source and the final version.

Finish one task at a time for long or sensitive documents. PDFolio uses the same local download flow as other browser files, so your browser may ask where the result should be saved or show its usual download notification.

When the result is ready, download it immediately and open it in your usual PDF viewer to make a final check. You can then use Clear task data to release temporary file references from this browser tab. PDFolio does not create an account, cloud folder, or server-side document history.

A private way to crop PDF pages

PDFolio handles the selected files in the active browser tab. A Web Worker on your device performs the PDF task so the interface can remain responsive; document bytes are not sent to a PDF processing server, upload queue, account database, or advertising platform.

Clearing the task, refreshing the page, or closing the tab releases the temporary in-memory task data. This local approach is useful for everyday documents such as contracts, statements, IDs, and school or work files that should not need to pass through a third-party service.
