AI Image Upscaler
Upscale any image to 2x or 4x resolution with AI. Increase the resolution of low-resolution photos, AI-generated art, storyboard frames, and production assets. The AI rebuilds textures, sharpens edges, and adds detail without artifacts. Output at 4K+ resolution for print, video, and large-format use.
How to upscale images with AI
Upload your image
Drop any image: photo, AI-generated art, screenshot, illustration, or storyboard frame. Supports JPG, PNG, and WebP formats. The AI handles any source resolution.
Choose upscale factor
Select 2x for double resolution or 4x for quadruple. The AI analyzes the image, predicts missing detail, and rebuilds textures, edges, and fine details at the target resolution.
Download your upscaled image
Your upscaled image is ready in seconds. Download the high-resolution result as PNG or use it directly in your creative project. Works seamlessly with storyboards, video generation, and print production.
Why choose this AI image upscaler
Most upscalers add blur or artifacts at high resolutions. Melies uses AI models trained on creative content to rebuild genuine detail. Textures, hair, fabric, and text stay sharp even at 4x.
True Detail Recovery
The AI doesn't just enlarge pixels. It predicts and generates missing detail. Textures, hair strands, fabric weave, and fine text are reconstructed at the target resolution with genuine clarity.
Built for AI-Generated Art
Most upscalers are trained on photos. Melies handles AI-generated images, concept art, and illustrations without introducing the artifacts common when upscaling synthetic content.
2x and 4x Scaling
Double or quadruple your image resolution. Take a 1024px AI-generated image to 2048px or 4096px. Output is sharp enough for print, large displays, and production use.
Batch Processing
Upscale multiple images at once. Process an entire storyboard, a set of product photos, or a batch of AI-generated concepts in a single workflow.
No Watermarks
Every upscaled image is clean. No watermarks, no branding, no restrictions. Download and use immediately in any professional context.
Pipeline Integration
Upscaled images feed directly into your Melies project. Upscale a storyboard frame, then send it to image-to-video. Enhance a character portrait, then use it as a reference. One platform, connected workflow.
AI upscaling models available on Melies
Choose from multiple AI upscaling engines, each optimized for different content types and quality levels.
Real-ESRGANFastFast, great for most images. Industry-standard super-resolution model that excels at general-purpose upscaling with sharp, clean results.
SeedVR2Best qualityBest overall quality with sharp detail recovery. Handles AI-generated art and photorealistic content equally well with minimal artifacts.
Clarity UpscalerFaces & colorOptimized for faces, portraits, and color-critical content. Preserves skin tones, facial features, and fine color gradients during upscaling.
AI image upscaling use cases
From AI art to old photos, the AI image upscaler improves any image for any use case.
AI-Generated Art
Upscale AI-generated images from 1024px to print-ready 4K+. Preserve the style and detail of FLUX, Stable Diffusion, and Midjourney outputs while adding the resolution needed for production use.
Low-Res Photos
Increase the resolution of old photos and smartphone shots. The AI predicts and generates detail that wasn't in the original. Small images become print-ready at 2x or 4x their original size.
Storyboard Frames
Upscale rough storyboard sketches and concept frames for client presentations. Go from quick AI thumbnails to presentation-quality images without regenerating.
E-commerce & Product
Enhance product photos for high-resolution listings, print catalogs, and banner ads. Get clean, sharp images at any size without reshooting.
Print & Large Format
Prepare images for posters, gallery prints, and large-format displays. AI upscaling gives you the resolution needed for physical media without visible artifacts.
Video Thumbnails
Upscale thumbnails, social media graphics, and cover images. Small source images become crisp, detailed assets ready for any platform or resolution.
How AI image upscaling works
Traditional image resizing uses interpolation, which averages nearby pixels to fill in gaps. The result is a larger image that looks blurry and lacks detail. AI upscaling takes a fundamentally different approach.
AI upscalers use deep neural networks trained on millions of image pairs at different resolutions. The model learns the relationship between low-resolution and high-resolution versions of the same image. When you upload a photo, the AI predicts what the missing high-resolution detail should look like and generates it.
This is called super-resolution. The AI reconstructs textures, sharpens edges, recovers facial features, and adds fine detail that never existed in the original file. The result is an image that looks naturally sharp at the higher resolution, not just stretched.
