Good to know.
Will the original image change?
No. The result is a separate download. Edited images are rendered by your browser and do not preserve original EXIF metadata. Color profiles and animated inputs may be normalized.
Is my input sent to a server?
No. This tool runs in your browser. KILIZU does not upload or store the values or files you enter here.
