Real-ESRGAN upscales and sharpens low-resolution images while preserving detail. Upload a small or blurry photo and Real-ESRGAN returns a higher-resolution version suitable for print, large displays, or further editing.
2× and 4× are the standard targets; some configurations support 8×. Final size is capped at 8192×8192 pixels on Free.ai to keep memory bounded.
PNG, JPG, WebP, HEIC, and BMP up to 10 MB. Animated GIFs are processed frame-by-frame.
Yes - modern enhancers include face-aware restoration. For very degraded portraits the dedicated /image/restore-face/ tool gives the cleanest result. Real-ESRGAN handles general scenes plus faces in one pass.
Real-ESRGAN runs on our own GPUs against your daily free pool first; then $5 → 200,000 paid tokens. About ~500 tokens per upscale.
Real-ESRGAN hallucinates plausible detail at the upscale step - it is not a forensic tool. For most consumer uses (web → print, mobile → desktop wallpaper, archive scan → display) the result is convincing.

Yes - /batch/ accepts a folder. Outputs land in /account/?tab=history with the original filename suffixed `-upscaled`. For folder-tree preservation use the API.

Yes. Free.ai grants commercial use of upscaled images. You must own the source you uploaded.
