AI Image Upscaler

Make small images sharper at 2× or 4×.

Upscale image

How it works

  1. Upload one image

    Choose a PNG, JPEG, or WebP. Small and compressed sources can work, but better inputs usually produce cleaner detail.

  2. Choose size and model

    Pick 2× or 4×, then match the Topaz model to the source. Enable face enhancement only when useful.

  3. Upscale and inspect

    Compare the output dimensions and inspect text, faces, edges, and fine texture before downloading.

Before you start

Files to upload
Upload a JPG, PNG, or WebP up to 20 MB. Animated GIFs are not supported. Image dimensions and output limits are checked before processing.
Access and cost

Tips for a better result

Start with the clearest source available, keep the main subject easy to identify, and choose settings that match the intended final size. Review the first output at full size before generating another variation, especially when the original contains small text, fine product edges, faces, or compressed detail.

Private processing

Tool outputs stay private. Only upload images you own or have permission to process.

More about this tool

Real 2× and 4× image enlargement

The selected scale changes both pixel dimensions. A 600 × 400 image targets 1200 × 800 at 2× or 2400 × 1600 at 4×, subject to provider limits.

Topaz models for different source images

Use High Fidelity for detailed sources, Low Resolution for small or compressed images, CGI for digital artwork, and Text Refine when lettering is the priority.

Frequently asked questions

Should I choose 2× or 4×?

Use 2× for a moderate enlargement and 4× when you need substantially larger dimensions. Four-times processing can expose artifacts in very small or damaged sources.

When should I enable face enhancement?

Enable it for photos with visible faces that need extra detail. Leave it off when identity preservation is more important or the image contains no face.

Will upscaling recover every missing detail?

No. AI can improve perceived detail, but it cannot guarantee accurate recovery of information that is absent from the source. Check text, logos, and faces closely.
