Upscaling is useful when an image is too small for its next job: old graphics, low-resolution thumbnails, small product photos, or social images that need a larger export. It is not magic, so a clean source image still matters. Start with 2x, compare edges and faces, then move to 4x only if the image still looks natural.
This page is designed as a browser-based upscaler rather than a file-upload service. The image is processed locally where possible, which helps when you are working with private drafts, client graphics, unreleased artwork, or website images that you do not want to send to another server.
