Questions about this tool
Which paper size should I choose?
Most of the world uses A4; the US, Canada, Mexico, Chile and the Philippines use Letter. NestPDF defaults to the right one for your region, and you can override it.
What's the difference between scale-to-fit and pad?
Scale-to-fit resizes the content to fill the new page; pad keeps the content at its size and adds white space around it.
Will the aspect ratio be distorted?
No. NestPDF preserves the aspect ratio and centres the content, so nothing is stretched.
Is my file uploaded?
No. Resizing happens in your browser and the document stays on your device.
