Frequently asked questions
Does cropping delete the content in the margins?
Cropping sets a new visible area for each page. Content outside the crop box is hidden in viewers and when printed.
Is the same crop applied to every page?
Yes. The margin percentages you choose are applied consistently across all pages of the document.
Is it really free?
Yes. Every PDFLark tool is completely free with no daily limits, no file-count caps, and no watermarks added to your documents.
Are my files uploaded to a server?
No. All processing happens locally in your browser using JavaScript. Your files never leave your device, which is why PDFLark works even on private or confidential documents.
Do I need to create an account?
No account, no email, and no sign-up. Open the tool, add your file, and download the result.
Which browsers and devices are supported?
PDFLark works in any modern browser — Chrome, Firefox, Safari, and Edge — on Windows, macOS, Linux, iPhone, and Android.
