Frequently Asked Questions

What is AI upscaling?

AI upscaling uses advanced neural networks to analyze your original low-resolution image and intelligently synthesize new pixels that accurately enhance edges, textures, and details, resulting in a much sharper high-resolution file.

How much can I upscale my image?

You can upscale your image up to 8x its original resolution natively in your browser. We enforce an auto-resize cap of 4000px on the final image payload to keep mobile devices memory-safe while still delivering sharp results.

Will the quality actually improve?

Yes. Unlike typical standard browser resizing (bicubic interp), our integrated tf.js neural tensor model accurately rebuilds artifacts reducing jagged edges dramatically.

What is the max file size?

To ensure proper memory limits and browser stability, we recommend files under 5MB. Large inputs over 1024px are algorithmically tiled into chunks under the hood to prevent browser crashes.
