Results vary with source quality, compression, image content, and upscale factor. AI upscaling can reconstruct plausible detail, but it cannot recover every detail that was never present in the source.

Built for real image work

Choose the right workflow for your image

Use the same upscaler for different image types, then adjust the factor and face enhancement to match the job.

01

Portraits and profile photos

Increase portrait resolution and optionally restore facial detail and skin texture with face enhancement.

02

Product and ecommerce photos

Enlarge product images for storefronts, marketplaces, presentations, and higher-resolution campaign assets.

03

Artwork and AI-generated images

Prepare illustrations and Nano Banana outputs for larger canvases while keeping edges and textures cleaner.

04

Older low-resolution photos

Reduce visible compression and improve clarity before archiving, sharing, or making a small print.

Scale with intent

Should you choose 1x, 2x, or 4x?

Higher is not always better. Start with the smallest factor that reaches your target dimensions, then inspect faces, text, and fine edges in the preview.

1xEnhance only

Sharpening, denoising, and face cleanup without changing dimensions

Keeps the original size while repairing blur, noise, and compression artifacts.

2xGood starting point

Web, social media, presentations, and light cleanup

Fastest and least aggressive; usually preserves the source character best.

4xHigh resolution

Product assets, detailed graphics, and small-format print

Creates a much larger file and may reveal artifacts in heavily compressed sources.

AI Image Upscaling for Sharper, Higher-Resolution Photos

Enlarge images online while preserving natural textures, clean edges, and important visual details.

01

Upscale Images up to 4x

Choose 1x, 2x, or 4x enlargement to turn small images into higher-resolution files for print, ecommerce, presentations, and creative projects.

02

Sharpen Details and Reduce Noise

The AI photo enhancer reconstructs fine details, smooths compression artifacts, and reduces noise without making edges look unnaturally harsh.

03

Enhance Portraits and Faces

Optional face enhancement improves facial details and skin texture in portraits, profile photos, and older low-resolution images.

04

Compare and Download the Result

Preview the original and upscaled image side by side, inspect the enhanced details, and download the finished high-resolution image.

Frequently Asked Questions

Answers about image resolution, supported formats, upscale factors, face enhancement, and usage rights.

What is an AI image upscaler?

An AI image upscaler enlarges an image while reconstructing details that ordinary resizing can blur or pixelate. This online tool can increase resolution, sharpen edges, reduce noise, and optionally enhance faces.

How do I upscale an image without losing quality?

Upload your image, choose an upscale factor, and let the AI reconstruct textures and edges as it increases resolution. Results depend on the source image, so start with the clearest original available and compare the preview before downloading.

Which image formats and file sizes are supported?

The image upscaler supports JPG, JPEG, PNG, and WebP files up to 10MB each.

How much does the AI image upscaler cost?

Upscaling costs 16 credits for every started 24MP of output: 16 credits up to 24MP, 32 up to 48MP, 48 up to 72MP, and 64 up to 96MP. The exact cost is shown before you start. New accounts receive 20 free credits.

Can I use an upscaled image commercially?

You may use an upscaled image in commercial work when you have the necessary rights to the source image and your use follows the site's terms. Upscaling does not grant rights to third-party content.

How long does AI image upscaling take?

Most images process in about 30 to 60 seconds. Processing time can vary with the original file size, upscale factor, and current demand.

Can I upscale an image to 2x or 4x?

Yes. Available options are 1x, 2x, and 4x. The 4x factor requires a Pro or Premium plan.

Do I need a prompt to upscale a Nano Banana image?

No. Upload the image directly, choose an upscale factor, and run the image upscaler. If you created the source with Nano Banana, this tool can increase its resolution without requiring another generation prompt.

What types of images can I enhance?

You can upscale portraits, product photos, landscapes, artwork, graphics, and older low-resolution photos. Face enhancement is especially useful for portraits and profile images.
