What it is
Increase your images' resolution up to 2× or 4× with a super-resolution model (ESRGAN) that runs entirely in your browser: photos are never uploaded to any server. Ideal for rescuing small photos, enlarging illustrations or preparing images for print without the pixelated look of plain resizing, in batch and with no watermark.
- AI upscaling 2× and 4× without the pixelated look of classic resize
- Before/after preview with a slider to compare the result
- Real batch: process multiple images and download a single ZIP
How it works
Upload your images
Drag one or more files into the upload area or import them from your Workspace. The AI engine starts preparing automatically.
Choose the factor
Select 2× or 4× enlargement depending on how much you want to increase the resolution.
Upscale and download
Click "Upscale", compare original and result with the before/after slider, then download the single images or the ZIP.
Features
AI 100% in-browser
The super-resolution model runs locally via WebGL/WASM. Your images never leave the device.
2× and 4×, no watermark
Full-resolution output, no watermarks, no server queues and no daily limits.
Before/after comparison
An interactive slider to instantly see the detail gain over the original.
Batch with ZIP
Upscale multiple images in sequence and download them all together in a single ZIP archive.
FAQ
No. Upscaling happens in your browser via an AI model that runs locally. Images never leave your device; only the model weights are downloaded (and cached) the first time.
Super-resolution is heavy: the time depends on the image size, the chosen factor and your device. Very large images can take several seconds; that's why we process in tiles to avoid running out of memory.
Classic resize enlarges the existing pixels and produces a pixelated image. The AI upscaler reconstructs the missing details, producing sharper edges and more realistic textures.
