Häufig gestellte Fragen
What is AI image upscaling?
AI upscaling uses a deep-learning model (Real-ESRGAN) trained on millions of image pairs to intelligently add detail when enlarging, unlike traditional bicubic scaling which just blurs.
What is the maximum input size?
Input images up to 1000×1000 px (1 megapixel). At 4× this outputs a sharp 4000×4000 image.
How long does upscaling take?
2× takes about 5–15 seconds, 4× takes 15–30 seconds, and 8× (applied twice) may take 60+ seconds.
What file formats are supported?
JPG, PNG, and WebP are supported for both input and output.
Is it really free?
Yes — ScaleImg is completely free with no watermarks, no file limits per session, and no signup required.
