常见问题解答
Is this PDF cropper free?
Yes. You can crop PDF online for free without creating an account, installing a PDF suite, or adding a watermark.
Can I crop every page at once?
Yes. Leave the page range as 1-z to apply the same crop to the whole PDF, or enter a range such as 1-3, 6 to crop only selected pages.
Can I trim PDF margins and scanner borders?
Yes. Use the Trim margins mode to remove white margins, black scanner borders, or extra page edges from the top, right, bottom, and left sides.
Does cropping lower PDF quality?
No. The cropper imports PDF pages into a new page size without rasterizing or recompressing page content.
PDF文件最大尺寸是多少？
You can upload PDF files up to 1 GB, the same upload limit used by Convertr tools.
上传的 PDF 是私密的吗？
Files are processed in short-lived temporary storage and automatically deleted after processing. Filenames, PDF text, and document contents are not sent to analytics.
