Yes, it is completely safe. Unlike other services that upload your files to remote servers, our tool uses advanced JavaScript to process everything directly on your computer. Your files are never seen by anyone else.
Will resizing distort my text or images?
No. Our tool scales the pages proportionally and centers them on the new canvas size. This guarantees that your content maintains its original aspect ratio without any stretching or distortion.

Absolutely! Our platform is fully responsive and works perfectly on iOS and Android devices. You can easily select a PDF and change its dimensions directly from your smartphone or tablet.
What happens to landscape pages?
Our intelligent resizing engine detects the orientation of each page. If a page is landscape, it will apply the landscape dimensions of your target size, ensuring the page remains perfectly formatted.
