Frequently asked
Common questions
Will resizing stretch my PDF content?+
No. Kukureku uses one proportional scale factor so the original aspect ratio is preserved. Extra page area can remain on the top or right when aspect ratios differ.
Are annotations preserved?+
Kukureku scales common PDF annotations together with page content. Complex interactive forms or unusual annotation types should still be reviewed after download.
Is my PDF uploaded?+
No. Page resizing runs locally inside your browser.
