Frequently Asked Questions

How does the upscaling work?

The tool leverages your browser's native hardware-accelerated canvas API with high-quality image smoothing enabled to intelligently interpolate pixels as the image dimensions are multiplied.

Are my photos uploaded anywhere?

No. Unlike other AI upscalers that require uploading your photos to a remote server and waiting in a queue, our tool processes the data locally directly on your CPU/GPU.

Is there a file size limit?

There is no hard limit imposed by the tool, but very large images (e.g., trying to 4x upscale an image that is already 4K) may cause your web browser to run out of memory.
