Helpful tips
Get the best result
Crop the same margins from every page
Enter top, right, bottom, and left margins in millimeters. Kukureku applies them to each page.
Use small values first
Try 5–10 mm when trimming white borders, then review the downloaded result.
Cropping is not redaction
Crop changes the visible page area but does not securely erase content outside the crop box.
Frequently asked
Common questions
Does Crop PDF permanently delete hidden content?+
No. Cropping changes the visible page area. Content outside the crop box may still exist inside the PDF, so do not use cropping to hide sensitive information.
Can I crop different pages by different amounts?+
This focused tool applies one set of margins to every page. A future visual crop workflow may support page-by-page cropping.
Is my PDF uploaded?+
No. The crop operation runs locally inside your browser.
