Image editing questions
Can I crop an image by dragging its edges?
Yes. The visual crop frame has draggable corners and edges, with optional aspect-ratio presets for common formats.
Will a transparent background stay transparent?
PNG and WebP can preserve transparency. JPEG does not support transparency, so the selected JPEG background color is used instead.
Are images uploaded for editing?
No. The image is decoded, edited, and exported locally in your browser.
