Honest compression, honest limits
Everything on this page is computed on your device. The one thing it will never do is upscale — enlarging is the app's priced Upscale operation, because adding detail takes AI, not resampling.
In the app, with credits
Going bigger than the original is real generation work — the Upscale operation adds detail with AI instead of faking it with resampling, which is why the free compressor only ever scales down.
Need the pattern itself, not just a smaller file?
TextileDesign generates, repairs, and upscales textile patterns with credits shown before every run. The free tools stay free either way.
