Are my files uploaded?

No. Fix page size runs entirely in your browser. Your PDF never leaves your device.

What is the difference between Fit and Fill?

Fit scales each page to fit inside the target size, adding margins if needed so no content is cropped. Fill scales to fill the target size, which may crop content at the edges.

Can I use custom page dimensions?

Yes. Choose “Custom...” and enter width and height in inches or millimeters.
