立即试用常见问题
Upload the PDF, drag a box over the first-page preview to mark the area to keep, and download — the same crop is applied to every page. Free and fully in-browser.
usageNo — the tool sets the PDF crop box, so viewers and printers show only your selection while the underlying content is preserved. The crop can be reversed in a PDF editor.
qualityYes — draw the crop box around the content area and the uniform margins disappear on every page. This also makes PDFs much more readable on phones and e-readers.
usageYes — the selection is applied proportionally to every page, which is what you want for uniformly scanned or exported documents. For per-page work, use Organize PDF or the PDF Editor.
featuresNo — cropping runs entirely in your browser with pdf-lib. The file never leaves your device.
privacyCrop PDF 如何助您完成任务
它每天都在解决真实的问题——服务企业、创作者和日常任务。找到适合您的用例，几秒即可开始。
Remove Scanner Black Edges
Scans often carry dark borders or punch-hole shadows — crop them out of every page in one drag for a clean, professional document.
Make PDFs Readable on Phone and E-Reader
Trimming wide academic margins makes the text column fill a phone or Kindle screen — no more pinch-zooming every page.
Focus a Drawing or Diagram
Crop architectural plans or charts to the relevant detail before sharing, so reviewers see exactly the area under discussion.
Tidy Slide Exports
Slide decks exported to PDF often float in white space — crop to the slide bounds for edge-to-edge presentation pages.
