完全ガイド: PDFを切り取る

Cropping a PDF lets you adjust the visible area of each page, removing unwanted margins, white space, or content around the edges. This is useful for trimming excessive margins from scanned documents, removing printer marks and bleeds, focusing on a specific area of a technical drawing, or optimizing documents for screen reading by eliminating wasted space. iLoveDoc's Crop PDF tool provides a visual cropping interface where you can define the exact crop area on each page. You can crop all pages uniformly or adjust individual pages separately. The cropping is non-destructive in the sense that it adjusts the viewable area rather than permanently deleting content outside the crop zone. However, for most practical purposes, the resulting PDF will only display and print the cropped area. Processing runs locally in your browser.

PDFを切り取る に関するよくある質問

Can I crop each page differently?

Yes. You can set individual crop areas for each page, which is useful when pages have different layouts or margin requirements.

Is the cropped content permanently deleted?

Cropping adjusts the visible area (crop box) of the PDF. The content outside the crop may still exist in the file structure but won't be visible or printable.

Can I crop to remove margins?

Yes. This is one of the most common uses — removing excessive margins to maximize the content area, especially useful for reading on screens or tablets.

Does cropping change the page size?

Yes. The resulting page dimensions will match your crop area. This can change the document from A4 to a custom size, for example.

Can I undo a crop?

Since the original file is preserved, you can always re-upload it and try a different crop. Once downloaded, the crop is applied.
