Upscale Image

Turn low-resolution photos into high-definition masterpieces. WaveSpeed's AI Upscale Image technology doesn't just stretch pixels; it intelligently reconstructs lost details, sharpens edges, and removes noise. Whether you need to prepare a small logo for print, restore an old family photo, or enhance an anime illustration, upscale up to 4x or 8x instantly.

How It Works

Three simple steps to upscale any image with AI.

Upload Your Image

Drag and drop or select any image from your device. We accept all common formats including JPEG, PNG, WebP, and TIFF. Images up to 20MP are processed instantly, and larger files are handled through our batch pipeline. Try the Image Upscaler free tool for a quick test.

Select Model & Scale

Choose your upscaling model and target scale factor (2x, 4x, or 8x). Real-ESRGAN excels at photographs and real-world images. SwinIR is ideal for illustrations and anime art. Our "Auto" mode analyzes your image and selects the best model automatically. Also works with the Video Upscaler for moving content.

Process & Download

Processing takes 2-10 seconds depending on resolution and model. Download your upscaled image in the original format or choose a different output format. Enterprise users can use our API to batch-process thousands of images. Combine with the Face Enhancer for portrait-specific improvements.

Incredible Clarity

AI Art Finalization

Generate an image at 512x512 with FLUX or SDXL, then upscale to 2048x2048 or higher. The AI adds crisp details to skin pores, fabric weave, and foliage that the base model hinted at but never rendered.

E-Commerce Zoom Views

Turn standard product photos into high-resolution zoom-ready assets. Customers can inspect fabric texture, stitching, and material quality at 4x magnification without any loss of clarity.

Print Production

Upscale web-resolution images (72 DPI) to print-ready quality (300+ DPI) for posters, banners, and marketing materials. 4x-UltraSharp preserves sharp edges even at billboard-scale output.

Old Photo Restoration

Combine upscaling with the Face Enhancer to restore scanned family photos. The AI recovers facial details and sharpens backgrounds from low-resolution scans.

Q & A

How does AI Upscale Image differ from Photoshop?

Traditional tools use "Bicubic Interpolation," which simply blurs pixels to make the image larger. AI Upscaling uses Deep Learning to "hallucinate" plausible details based on millions of training images, actually adding information that wasn't there before.

What is the maximum resolution?

Our standard API supports upscaling up to 8K resolution (7680x4320). For enterprise plans, we support tiling workflows that can generate even larger images for billboards or print.

Can it fix blurry text?

Yes, to a degree. AI models are excellent at sharpening edges, which makes text more readable. However, if the text is completely illegible in the original, the AI might guess incorrectly.

Does it work on faces?

Absolutely. We integrate specialized Face Restoration models (like GFPGAN and CodeFormer) into the upscaling pipeline. These detect faces and rebuild features separately for maximum realism.

Is it safe for printing?

Yes. AI upscaling is widely used in the print industry. By increasing the pixel count, you increase the DPI (Dots Per Inch), allowing small web images to be printed clearly on A4 or even A3 paper.
