Frequently Asked Questions

Will resizing distort my image?
Enable 'Lock ratio' — it keeps proportions correct automatically.
What's the maximum resolution?
Limited by browser canvas memory. Up to ~10,000×10,000px typically works.
Does upscaling add detail?
No — upscaling interpolates pixels. Only downscaling preserves sharp quality.
Are images uploaded?
No. Canvas API runs in your browser.
