Upscale Image In One Click — AI Photo Enlarger 4x, Higher Resolution

Right-click any image to save a larger PNG or WebP with on-device AI, no uploads, account, or watermark.

Upscale Image In One Click saves a copy four times wider and taller from the right-click menu. The on-device AI upscaler removes JPEG blockiness and gives photos and drawings sharper edges and texture than classic resizing. You can make an image bigger without uploading it to a service. 🖼️ WHAT YOU GET • Start from any picture with "Download upscaled" in its context menu. • See the final resolution and an estimated time right in that menu item before you click. • Choose PNG or WebP in the popup before saving. • Keep the original proportions, with output capped at 16,384 pixels per side. • Use the extension free, with no account or watermark. 📏 MODES The popup offers AI (the default) and No AI. The neural super-resolution model runs on your computer, using the graphics card through WebGPU or the processor when that is unavailable. A 512×512 picture takes about a second with a graphics card. The model ships inside the extension; no separate download is needed. The classic option uses high-quality resampling with pica. It produces smooth results without inventing shapes, making it the preferred choice for screenshots and small text. 🔧 HOW IT WORKS 1. Open the popup to choose a mode and output format. 2. Right-click the source and select "Download upscaled". 3. Wait for processing on your computer. 4. Find the enlarged copy in Downloads. 💡 GOOD TO KNOW Can I increase image resolution for a minimum-size requirement? Yes, the saved copy has more pixels, subject to the side limit. Check its dimensions: larger sources receive less than the target 4x enlargement. More pixels alone do not guarantee visual quality. Will it sharpen a blurry photo or keep faces and lettering exact? The neural mode predicts plausible detail; it cannot recover real detail that was never there. Faces and small text can change shape. Choose No AI when preserving those shapes matters, especially for screenshots; a blurry source will still have limits. What happens with big files? Neural processing supports sources up to about 2000×2000 pixels with a graphics card, or about 1000×1000 pixels without one. Larger sources automatically use the classic method, and the page notice tells you so. 🔒 PRIVACY Nothing is uploaded. Processing stays on your computer, and local storage only remembers your chosen format and mode.
