This free online tool enlarges small images with as few artifacts (blocky pixels, jagged edges) as possible. Small images are also enlarged with AI (Real-ESRGAN), which keeps edges sharp. Besides, it uses several interpolation filters which suit different types of images (e.g. line art vs. photographs), so you can choose your preferred version from the results.
Max. size of the uploaded image: 3000 x 3000 pixels.
Size of the enlarged image The enlarged image can be up to 4000 pixels wide and high. You can enter decimals like 2.5.
Or: enter the width or the height, and the image keeps its proportions. With both, it gets exactly this size. Width and height are used instead of the zoom factor.
