Frequently Asked Questions

Does cropping remove content permanently?▾

The content outside the crop box is hidden from viewers. The PDF file size may not decrease significantly, but PDF readers will not show the cropped area.

Can I set different margins for each page?▾

Yes — use 'Per page' mode to set individual margins. You can also use 'Apply to all' from any page to propagate those settings.

Are files uploaded anywhere?▾

No. Everything runs in your browser using pdf-lib and PDF.js.
