Upscale Any Image with Local AI

Image Upscaler

Low-res photos, compressed screenshots, and tiny logos all lose detail when enlarged. SEO Time Machines runs Real-ESRGAN directly in your browser to restore that detail — without uploading a single pixel.

Every Upscaler Wants
Your Images

You find the perfect image but it is 400 pixels wide. You need it at 1600. Every free upscaler asks you to upload it to a server, wait in a queue, and hope the result does not look like an oil painting.

Paid tools like Topaz Gigapixel cost money and run as separate desktop apps. Either way, your image leaves your machine.

For logos and line art the situation is worse. Standard upscaling smears hard edges into soft gradients, turning crisp vector-style graphics into blurry mush.

Image Upscaler runs two specialised AI models locally in your browser. Your images never leave your machine. Not even for a second.

Drop. Pick. Done.

Open the Image Upscaler from the toolbar, Quick Launch, or right-click any image on any page. Pick Photo mode for natural images or Logo and Line Art mode for flat-color graphics.

Choose your scale — 1× to clean compression artifacts without resizing, or 2× through 4× to enlarge.

Drop one file or an entire batch. The bundled Real-ESRGAN model runs locally on your GPU via WebGPU, with automatic CPU fallback on older hardware. Results appear in a before-and-after grid ready to download individually or as a ZIP.
