Frequently Asked Questions

Are these images generated locally?

Yes! All images are rendered instantly in your browser via HTML5 Canvas.

What resolution limits are supported?

Export anywhere from small thumbnails up to sharp 4K resolutions (8192px max dimension) with smart orientation handling.

Should I choose PNG, JPEG, or WebP?

PNG offers lossless quality (best for sharp solid blocks, though file sizes can be larger). JPEG uses lossy compression yielding smaller files, but can occasionally introduce subtle banding on fine gradients. WebP provides modern high-compression efficiency with great quality and small file sizes across both solid colors and gradients.
