Frequently asked questions
Are my photos uploaded?
No. Everything runs in your browser. The image never leaves your device.
Is it free?
Yes. No credits, no account, and no watermark.
How much does it upscale?
A fixed 4× with super-resolution: it rebuilds detail, not just stretches pixels.
Which formats are supported?
Input PNG, JPG, and WebP. Download as PNG or compressed WebP.
Do I need to register?
No. Open the page, upload the image, and download the result.
Which browser do I need?
A modern browser (recent Chrome, Edge, Firefox, or Safari). WebGPU speeds things up when available.
Can I use the result commercially?
Yes. The upscaled image is yours. Also respect the rights of the original photo.
Is there a size limit?
Very large images are processed in tiles. On phones, huge photos may be slower due to memory.
Which AI model does EscalaImagen use?
Real-CUGAN 4× conservative, run locally with TensorFlow.js in your browser.
Is there a watermark?
No. PNG and WebP exports come out clean.
Does it work offline?
After the first model download (which can be cached), upscaling runs locally. You need a network the first time.
Does it work for old photos?
Yes. A typical case: recovering detail in portraits or scanned documents with low resolution.
