Quick answer
Image upscaling increases a picture’s resolution using AI that reconstructs plausible detail — sharper edges, cleaner textures, restored faces — instead of just enlarging pixels. It rescues low-resolution photos, prepares AI-generated images for print or large displays, and cleans up compression artifacts. A good upscaler can take a small web image to print-ready size without the soft, blurry look of traditional resizing.
Classic enlargement interpolates between pixels, which is why zoomed images look smeared. AI upscalers were trained on millions of low/high resolution pairs, so they predict realistic detail that was never in the file.
Common uses: enlarging AI-generated art (models often output around one to two megapixels), restoring old or compressed photos, and preparing assets for print, where resolution requirements are unforgiving.
VdoBloom includes an image upscaler in its image toolkit, alongside the video upscaler for footage.
