Image Upscaler

KeepVid Image Upscaler was built for the small, low-resolution photo that still deserves to look sharp. Enlarging used to mean blurry stretching or a paid desktop app, and most online tools sent your picture to a server first. Our tool runs the AI model entirely in your browser, so you can enlarge any image 2x or 4x and recover real detail in seconds. It reads JPG, PNG, and WebP, and shows the exact before and after dimensions so you know the new size up front. A side by side preview lets you compare the original and the enlarged version before you save anything. Nothing is uploaded, nothing is installed, and no account is required.

Behind that simplicity is a neural network that predicts new pixels instead of just resizing old ones. It uses a super-resolution model trained on millions of images, so lines and textures stay crisp rather than turning into soft blocks. You can choose 2x for the web or 4x for print, and the result downloads as a lossless PNG at the new resolution. The model works especially well on faces, text, and product edges where plain resizing would smear detail. Transparent PNGs are preserved, so graphics keep their clean edges after enlargement. Because everything runs locally on your device, your photos never leave your computer, which keeps private pictures safe. In practice, Image Upscaler is used for product shots, old scans, AI art, and screenshots that need extra pixels. It is free, works on phones and desktops, and needs no plugins.
