Frequently Asked Questions

Does my file get uploaded?
No. The resizing runs entirely in your browser on your own device. Your PDF is never sent to a server, never stored, and never seen by us. Safe for confidential construction drawings and NDA work.
How does resizing to A4 or Letter work?
Each page is set to the target size, and the existing content is scaled to fit inside it and centered, keeping its proportions so nothing is stretched. Landscape pages stay landscape and portrait pages stay portrait by matching the target to each page's orientation.
Can I scale by a percentage instead of a fixed size?
Yes. Choose Scale and enter a percentage (for example 50% to halve the page, or 200% to double it). Each page's size and content are scaled by that amount, which is handy for fitting a large drawing onto a smaller sheet.
Will the text stay sharp and selectable?
Yes. This resizes the real PDF content rather than flattening it to an image, so vector lines stay crisp at any zoom and text stays selectable. For opening and marking up very heavy 50-200 MB+ CAD sets, the Ncored desktop app is built for that.
