How RealESRGAN Upscaling Works
Learn how the RealESRGAN model intelligently improves resolution for sharper, more professional images
RealESRGAN Technology
Using the RealESRGAN model optimized for real-world photos. Compared with traditional ESRGAN, it greatly reduces artifacts and improves detail reconstruction — ideal for real photographs.
Adaptive Upscaling
Supports 1–8× smart upscaling, default 2×. Choose the factor by original resolution and purpose: 4–8× for low-res images; 2–4× for high-quality images.
Quality Assurance
Preserves color accuracy, enhances detail clarity, and reduces noise and artifacts. Works for photos, illustrations, design drafts, and more.

FAQ
How is RealESRGAN different from ordinary upscaling?
RealESRGAN is a deep learning model optimized for real-world images. It reconstructs details rather than simply stretching pixels, noticeably reducing artifacts and preserving natural look — especially for real photographs.
What formats and sizes are supported?
Supports JPG, PNG, and WebP. Each file can be up to 20 MB. For best results, upload higher-quality originals.
How do I choose the right scale factor?
We recommend 1–8× upscaling, default 2×. For low-resolution old photos, use 4–8×; for modern high-quality photos, use 2–4×. For web display, 2–3×; for print, 4–8×.
When should I enable face enhancement?
Enable face enhancement when the image contains faces to better restore facial details and textures. For landscapes and objects, turn it off for more natural results.
Can I use upscaled images commercially?
Subscribers may use generated images for commercial purposes.
What about artifacts after upscaling?
RealESRGAN focuses on artifact control. Compared with the original ESRGAN, it greatly reduces over-sharpening and unnatural artifacts. Results depend on source quality and content.
