How It Works
Three steps from source image to upscaled PNG.
The image workflow is intentionally minimal: load, preview, export. No sliders to tune, no accounts to create, no watermarks on the output.

FAQ
Common questions about the free AI image upscaler.
What image formats does Upsampler support?
The image upscaler accepts PNG, JPG, and WebP files. The upscaled output is exported as a PNG for lossless quality.
How much does the image upscaler enlarge my photo?
Upsampler applies a 2x upscale. A 800 × 600 image becomes 1600 × 1200, a 1920 × 1080 photo becomes 3840 × 2160, and so on.
Does Upsampler work for anime and illustrations?
Yes. The auto-profiler detects illustration-style content and switches to a model optimized for clean edges and flat color areas.
Is my image uploaded to a server?
No. All image processing runs locally in your browser using WebGPU. Your files never leave your device.
Is the image upscaler free?
Yes, completely free. No account, no credits, no watermarks. Open the page, load your image, and download the result.
