Frequently Asked Questions
How do I crop my PDF visually?
Upload your file, then drag the red selection box corners over the area you wish to keep. You can also click 'Auto-Magic' to let our AI find the margins for you.
Can I crop just the first page?
Yes! Use the 'Crop Scope' dropdown to choose between applying the crop to all pages or just the current page you are viewing.
Does it work for Kindle/Kindle Paperwhite?
Yes! This is the #1 use case. By removing white margins, you make the text larger and much easier to read on small E-ink screens.
Will it reduce my file quality?
No. Cropping only hides the area outside the box. It does not re-compress or degrade your images or text.
Is my data private?
100%. Harsh Cyber Cafe uses client-side logic. Your document is processed on your device and never uploaded to any cloud server.
