How to crop a PDF

1
Upload one PDF or several at once from your device, or pull them from Google Drive, Dropbox, or OneDrive. Without an account: 1 file, up to 80 MB. With a free account: up to 3 files, 80 MB each and 120 MB total.
2
Drag the crop handles around the page to trim margins or focus in on a specific section. A live preview shows the new shape as you adjust.
3
Pick the scope: apply the crop to just the current page, a custom range of pages, or the whole document.
4
Click Crop PDF. The crop area becomes the new page boundary, so the file opens and prints at exactly that size - everything outside it is hidden from view.
5
Download your cropped PDF, save it back to the cloud, or send it straight into another tool like Merge or Sign.

Why use our Crop PDF tool

Drag-and-drop crop handles
Pull the edges of the page in any direction. The preview updates live so you always see exactly what stays and what goes.
Trim white margins
Remove unwanted padding around the content so the page fills the screen edge to edge - ideal for prepping scans for e-readers.
Focus on a section
Need just the chart, the signature box, or one part of a poster? Drag the box around that section and crop everything else away.
Per-page, range, or full-doc
Apply your crop to a single page, a range like 1 to 12, or the entire document - whichever fits the job.
Live preview
What you see in the editor is what you get in the output. No surprises, no recropping after the fact.
Lossless crop
Text, images, and fonts stay sharp. The crop changes the page box, not the underlying content quality.
Instant in-browser engine
For everyday PDFs the crop is applied right in your browser - nothing is uploaded, so it's instant and private, and it correctly handles pages with offset page boxes.
Batch multiple files
Signed in, crop up to 3 PDFs in one go - each keeps its own per-page crop, and they download together as a ZIP.
Cloud import
Pull files from Google Drive, Dropbox, or OneDrive without a local download step.
Workflow Ready
Send the cropped PDF straight into Merge, Compress, Sign, or any other tool without re-uploading.
Free, no watermark
No watermark on the PDF, no signup needed for single jobs, no per-day cap on crops.

Frequently asked questions

PDF 怎么免费裁剪页面?

在上方添加 PDF,拖动裁剪框的边缘框住要保留的部分,选择应用到哪些页面,然后下载。完全免费,无水印,无需注册。

PDF 怎么裁剪白边?

把裁剪框的边缘拖到内容边上再应用即可。裁剪框由你自己画,不会自动识别,所以保留哪些内容完全由你决定。

怎么一次裁剪所有页面?

画一次裁剪框,应用到全部页面,或应用到某个范围(如 2-10)。所选页面都会裁成同一区域,适合版式固定的文档。

裁剪会删除框外的内容吗?

不会。框外的内容只是被隐藏,仍然保存在文件里,在某些编辑器中可能重新显示。要彻底删除敏感内容,请使用 涂黑 PDF。

PDF 裁剪后怎么变成 A4 纸大小?

裁剪会按原比例保留所选区域,不会把页面缩放成某种纸张尺寸。打印时选择“适合页面”即可铺满 A4 纸。

怎么只裁剪出一页中的一部分另存为图片?

先把这一页裁剪到需要的区域,再用 PDF 转 JPG 把裁剪后的页面导出为图片。

裁剪后文件会变小吗?

基本不会,因为隐藏的区域仍在文件中。要缩小文件,请在裁剪后使用 压缩 PDF。

裁剪错了可以撤销吗?

可以。“撤销”和“重做”逐步回退或恢复裁剪框的修改,“重置”回到整页。下载前不会保存任何改动。

可以批量裁剪多个 PDF 吗?

免费账户一次最多 3 个 PDF(单个 80 MB,总计 120 MB),裁剪后的文件打包成一个 ZIP 下载。

文件安全吗?

安全。PDF 在你的浏览器里、在你自己的设备上裁剪。只有在极少数浏览器无法处理的情况下,文件才会通过 HTTPS 发送到我们的服务器,并在一小时内自动删除。
