FAQ
How big is too big?
We recommend staying under 2000×2000 pixels for source images. Larger inputs combined with 4x upscaling can exceed processing limits.
Does it work on cartoons or anime?
Yes. Real-ESRGAN handles both photographic and illustrated content well, though the best results come from realistic photos.
How long does it take?
Typically 15–45 seconds depending on input size and scale. Larger images and higher scale factors take longer.
Are my images stored?
No. Uploads are processed through our AI pipeline and the output is returned to you. We don't permanently store your images.
