Which Upscaler is Right for You?

From instant free to professional publication quality.

Standard (Free)

Fast standard upscaling. Instant, no account needed. Good for basic size increases where speed matters most.

Free - No account needed

AI Enhanced (Free with account)

EDSR neural network reconstructs real texture and fine details. Significantly sharper than standard upscaling. Runs on CPU - Takes 15-30 seconds.

Free - Sign in required

Pro AI Upscaling (Pro plan)

Publication-quality AI upscaling. Universal adds detail, Pro Precise stays true to the original, Pro Creative reimagines with artistic enhancement.

What People Upscale

AI upscaling works on any raster image - here are the most common workflows.

AI Generated Images
Upscale images generated by GPT Image, FLUX, Recraft or any other model to print-ready resolution.
Photos and Portraits
Enlarge old or low-resolution photos while recovering fine detail - faces, textures, and backgrounds.
Game and Concept Art
Scale concept sketches and game sprites to display or print resolution without losing detail.
Product Images
Make product photos larger and sharper for e-commerce, marketplace listings, and print catalogues.
Print and Large Format
Prepare images for large-format printing - posters, banners, canvas prints, and exhibition displays.
Social Media and Web
Resize small images to meet platform requirements for YouTube thumbnails, Instagram, LinkedIn, and more.

Frequently Asked Questions

What is AI upscaling?
AI upscaling uses neural networks to intelligently increase image resolution. Unlike simple resizing, it reconstructs fine details, textures, and edges rather than just stretching pixels - producing sharper, cleaner results.
What is EDSR and how does it work?
EDSR (Enhanced Deep Super Resolution) is a neural network trained on millions of image pairs to learn how high-resolution textures correspond to low-resolution inputs. It reconstructs probable fine details rather than guessing blindly from pixel patterns.
2x vs 4x - which should I choose?
2x is a good starting point for most uses - it doubles the linear resolution (4x pixel count). 4x is better for print or large-format display. Keep in mind that a 512px image upscaled 4x becomes 2048px - very large and may take longer to process.
Why does AI Enhanced take longer?
AI Enhanced uses a neural network that runs on CPU and requires significantly more computation than standard upscaling. Expect 15-45 seconds depending on image size - The quality improvement is usually worth the wait.
What image formats are supported?
Upload JPG, PNG, or WEBP images up to 10 MB. The upscaled result is returned as a PNG. For the best quality input, use PNG where possible as it's lossless.
What are the Pro upscaling methods?
Pro members get access to three additional AI upscaling methods: Universal (best for photos and illustrations), Pro Precise (ideal for portraits - stays close to the original), and Pro Creative (adds artistic enhancement - great for art and stylised images).

Image Upscaling Workflow

Upscaling works best when the image is clean, but too small for where you want to use it. Choose the lightest step that solves the problem, then check the final image at real publishing size.

2x for normal web use

Choose 2x when you need a cleaner image for a blog, product page, profile or social post. It usually keeps artifacts lower than extreme enlargement.

4x for larger previews

Use 4x when the source is clean and you need more room for posters, slides, thumbnails or marketplace images. Check small text carefully.

Clean before enlarging

Use the Image Enhancer first if the image has noise, dull color or weak contrast.

Check the image before you download

Portraits

Zoom in on eyes, teeth, hairlines and skin texture. These areas show bad upscaling first. If faces look waxy or over-sharp, try a smaller scale.

Products

Inspect labels, logos, edges and fine patterns. If text becomes warped, the source file is probably too small for reliable enlargement.

AI art and graphics

Look for strange hands, repeated textures, broken lines or odd background details. Upscaling can make small generation flaws easier to notice.

Use the right finishing step

If the image is poorly framed

Crop it first. Upscaling a bad crop only gives you a larger version of the same composition problem.

If the image is noisy or dull

Run a gentle enhancement before enlarging. Cleaning noise and contrast first gives the upscaler better source detail to work with.

If the file is already big

Do not upscale just to reduce load time. Use the Image Compressor so the page stays fast.

Keep three versions: the original, the upscaled image and the final compressed file. That gives you a clean fallback if the enlargement creates artifacts after you place it on a real page, slide or marketplace listing.
