Frequently asked questions

Will text remain searchable and selectable?

The tool changes page bounds instead of rebuilding pages as images, retaining the source text and vector content.

Is information outside the crop permanently removed?

No. Original content outside the CropBox remains in the PDF. Do not use this tool to erase private information.

Do I need to upload my file?

No. Your selected file is processed in your browser. No account is required, and the original file stays unchanged.
