How does the free AI image upscaler work?

Our upscaler uses Real-ESRGAN and Real-CUGAN deep learning models running directly in your browser via WebGPU or WebGL. Your images are processed locally — they never leave your device.

What upscale factors are supported?

We support 2x and 4x upscaling. 2x doubles each dimension (4× pixels), while 4x quadruples each dimension (16× pixels). Choose based on your output resolution needs.

Are my images private and secure?

Yes. All processing happens entirely in your browser using local GPU acceleration. No image data is ever uploaded to any server.

Which AI models are used for upscaling?

We use Real-ESRGAN for general and anime images, and Real-CUGAN for 2D/illustration art. Each model is optimized for specific content types to deliver the best results.

AI super resolution

Upscale images online for free with AI super resolution. Veclify enlarges photos up to 4x using Real-ESRGAN and Real-CUGAN models, all in your browser.

Because processing is on-device, your images never leave your machine.

2x and 4x enlargement

Choose a scale factor and let deep-learning models reconstruct detail, reducing the blur you get from ordinary resizing.

Privacy-first upscaling

Models run locally via WebGPU or WebGL, so sensitive photos stay on your device while you sharpen and enlarge them.
