Is this AI enlargement or ordinary resizing?
An image restoration model estimates finer details at 2× resolution. 4× uses two AI passes. Compare before and after, especially around text and faces: estimated detail can differ from the original scene. Use Resize Image when you only need exact dimensions.
Are full-size downloads free and private?
Yes. There is no account, watermark or paid API. A model and its processing files download the first time you start; your images stay in your browser. Large images can take several minutes. Cancel stops processing and keeps completed images.
Which files and sizes are supported?
JPG, PNG, WEBP, BMP and the first frame of GIF. Up to 10 images, 100MB each and 200MB combined. Each enlarged result may be up to 16 megapixels and 8,192 pixels per side: at most 4MP input for 2× or 1MP input for 4×. PNG and WEBP keep transparency; JPG uses white. Multiple results download in one ZIP.
