How to crop the margins of a PDF online
Upload the PDF you want to crop
Drag your file or click to select it from your computer.
Adjust the margins to remove
Choose how much to crop from the top, bottom, left and right as a percentage, to remove the white margins so the content fills more of the page.
Apply the crop and download
The crop is applied to every page of the document at once. Download your PDF with the adjusted margins, without uploading the file to any server.
Why crop the margins of your PDFs in PDFDocks?
Cropping white margins from a PDF — to better use space when printing, or to fit it to a reader's screen — is a straightforward visual adjustment that shouldn't require uploading your document to an external server. In PDFDocks, cropping is done with JavaScript, directly in your browser: the file never leaves your device. You choose how much to remove from each side as a percentage, preview the result before applying it, and a new PDF is generated with adjusted margins across all pages at once, with nothing ever traveling over the internet.
Can I crop specific pages?
+
Yes. Your file is never uploaded to a server: cropping is performed directly in your browser with JavaScript, so the PDF never leaves your computer at any time.
Will cropping reduce file size?
+
Yes. You can adjust the crop from the top, bottom, left, and right independently, depending on how much margin you want to remove from each side.
Is my PDF uploaded to a server when using this tool?
+
No. The entire process happens in your own browser, with the file never traveling over the internet at any time.
Will cropping affect quality?
+
Yes, there's no need to install anything. It works directly from your browser, on desktop or mobile, without creating an account or downloading additional software.
Does the crop apply to all pages at once?
+
Yes, the same crop is automatically applied to all pages of the document without you having to repeat the process page by page.
Is there a page limit for this tool?
+
We haven't set any artificial limits. Since the process happens in your own browser, you can work with documents of any size — the only real limit is the available memory on your device.
