AI Photo Enhancer & Upscaler — up to ×4 resolution

Free browser-based tool to enhance and upscale photos. The Real-ESRGAN ×4 neural network increases image resolution 2× or 4× and reconstructs real detail — sharp edges, texture, faces — while optional sharpen, contrast and saturation lift overall quality. Unlike a plain resize that just stretches pixels, the AI rebuilds them. Runs in your browser via WebGPU, no installation.

How to Enhance a Photo with AI

1
Upload your photo

Drag and drop or click to browse. JPEG, PNG, WebP, BMP and GIF supported, up to 50 MB.

2
Pick a scale

Choose ×2 or ×4 AI upscale for detail recovery, or Enhance only to keep original size.

3
Toggle enhance

Enable Enhance to apply sharpen, contrast and saturation — adjust with three sliders.

4
Process and download

Click Enhance photo. Compare with the before/after slider, then download as PNG, JPEG or WebP.

Boost your photo quality and resolution up to 4× in seconds

Features

Real-ESRGAN ×4 AI upscaling — recover detail in low-resolution and old photos
The Real-ESRGAN ×4 neural network runs on WebGPU to rebuild edges, texture and faces at ×2 or ×4 instead of just stretching pixels.
Optional sharpen, contrast and saturation pass — fine-tune the result with three sliders
An enhance pass works at any scale, including ×1, so you can sharpen and lift contrast even without WebGPU upscaling.
Before/after slider to compare the result instantly
A draggable wipe slider lays the enhanced photo over the original so you can judge the recovered detail before saving.
PNG, JPEG and WebP export — download in your preferred format
Save the upscaled result as PNG, JPEG or WebP; the first run downloads the ~50 MB model once and caches it for later.

FAQ

Which AI model do you use?

Real-ESRGAN ×4 (fp32, 65 MB ONNX). The same model used in the dedicated /video-upscaler tool — proven for recovering detail in low-resolution photos.

Why is WebGPU required?

Real-ESRGAN inference on CPU/WASM produces all-zero outputs (a black image). It needs a GPU backend, and WebGPU is the only browser GPU API that works reliably across vendors. Without WebGPU you can still use the Enhance pass (sharpen / contrast / saturation).

How long does ×4 upscale take?

A 1080p photo upscales to 4K in 5–20 seconds on a modern laptop with a discrete GPU. Mobile devices with integrated GPUs may take 30–60 seconds.

What is the difference between AI upscale and Enhance?

AI upscale increases the resolution by 2× or 4× using a neural network trained on millions of photos. Enhance is a classic sharpen + contrast + saturation pass — useful at any scale, including ×1 (no upscale).

Can I use it on mobile?

Yes. The tool detects WebGPU support — if your phone supports it (recent Chrome/Edge on Android), AI upscale works. Otherwise the Enhance pass is available.

What about HEIC photos from iPhone?

HEIC is not natively decodable by most browsers. Convert your HEIC photo to JPEG first using our /heic-converter tool, then enhance.
