Frequently asked questions
Does resizing affect the page content too?
Yes. Both the page dimensions and the content are scaled together, so everything stays in proportion.
Can I make a PDF bigger as well as smaller?
Yes. Choose any scale from 25% up to 200% to shrink or enlarge the pages.
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.
