How it works
Important
Keep an untouched copy of important source files. Browser processing depends on available device memory, and you should inspect every downloaded result before deleting the original.
Practical details
Frame a local photo as a square or circular transparent PNG profile picture with 256, 512, 1024, or 2048-pixel output presets.
A circular PNG is still stored on a square transparent canvas. Some platforms replace transparency or crop again, so preview the final upload on that service.
Lucaden adds focused presets, local file limits, output validation, privacy checks, and exact upstream attribution.
Questions
No. The pinned Cropper.js runtime reads a temporary object URL and exports through the browser canvas without an upload request.

Cropper.js 2.1.1 (MIT) supplies the interactive crop selection and transformed canvas export. The upstream project retains its original name, copyright, and license.
Open-source foundations
Lucaden documents its standards sources, architectural references, and permissive runtime dependencies while keeping this workspace consistent with the Lucaden interface.
