AI Image Upscaler
AI upscaling increases image resolution while reconstructing believable detail — skin texture, hair strands, building edges — instead of just interpolating pixels. Oakgen's upscaler supports 4×, 8×, and 16× ratios on photos, illustrations, and AI generations, returning results in under 10 seconds per image.
Key fact
Unlike Lanczos or bicubic resizing, AI upscalers reconstruct missing detail from learned priors — a 500×500 photo upscaled to 4000×4000 looks like it was shot at 4K.
Why AI Image Upscaling
Up to 16× resolution
A 512×512 AI generation becomes an 8192×8192 print-ready image with crisp edges and no pixelation.
Handles photos and art
Works on phone photos, scanned film, AI generations, illustrations, and vector-style art.
Face-aware restoration
Small or blurry faces are restored with natural skin texture and detail, not plasticky smoothing.
How it works
- 1Upload the imageAny format (JPG, PNG, WebP) up to 4096×4096 input. Larger inputs are pre-downsampled automatically.
- 2Pick upscale ratio4× is ideal for print. 8× for billboards or 4K video. 16× for extreme forensic zooms.
- 3Generate and downloadTypical 4× upscale completes in 6–10 seconds. Download as PNG or JPEG at full output resolution.

Frequently asked questions
How much does AI upscaling cost?
4× upscaling costs about 15 credits (~$0.06) per image on Oakgen. 8× and 16× cost more because they render larger tiles — typically 30 and 60 credits respectively.
Will upscaling fix a blurry photo?
AI upscalers restore sharpness in most cases, but they can't recover detail that wasn't captured. Heavy motion blur and extreme out-of-focus shots are the hardest cases.
What's the maximum output resolution?
16× on a 4096×4096 input produces a 65536×65536 output — large enough for billboard printing. Most users land in the 4×–8× range.
