Make any image 2x or 4x bigger — without the blur. PixelBoost uses Real-ESRGAN super-resolution AI to enlarge images while adding sharp, realistic detail. Where normal resizing stretches pixels into mush, PixelBoost reconstructs edges, textures and fine detail — so the enlarged image actually looks better. Everything runs locally on your PC. Your images never leave your machine — no uploads, no cloud, no account, no subscription. HOW IT WORKS Drop or pick an image, choose 2x or 4x, press Boost. The built-in Real-ESRGAN model reconstructs the image at higher resolution. Compare before and after side-by-side, then save as JPEG. PERFECT FOR • Enlarging photos for printing and framing • Upscaling small logos, artwork and game assets • Rescuing low-resolution images from old phones or the web • Preparing images for large displays and posters PRIVATE BY DESIGN 100% offline processing. No internet connection required after install. Your images stay yours.
