To render crisp pixel art in HTML5 Canvas without anti-aliasing blur, set ctx.imageSmoothingEnabled = false on the 2D context before drawing. Scale your sprites using whole integer factors, and apply the CSS rule image-rendering: pixelated to the canvas element so any browser-level upscaling stays completely sharp without interpolation blur.<\/strong><\/p>\n

Set ctx.imageSmoothingEnabled = false<\/code> on your 2D context before drawing sprites – by default this is true<\/code> and the browser blurs pixels when it scales an image up. Draw sprites at integer scale factors (such as 2x or 3x) so each source pixel maps cleanly to a block of screen pixels, which is exactly what MDN describes as the goal of a crisp pixel art look.<\/p>\n

What if I resize the canvas element with CSS?<\/h2>\n

Setting the canvas’s CSS width\/height larger than its internal width<\/code>\/height<\/code> attributes triggers a second, independent scaling step done by the browser, not by Canvas 2D. Add image-rendering: pixelated<\/code> (or crisp-edges<\/code> for wider browser support) to the canvas element’s CSS so that scaling stays nearest-neighbor too. Watch out: when the CSS size doesn’t align to an integer multiple of the device pixel ratio, some pixels render slightly larger than others, an unevenness MDN flags as a known limitation of pixelated<\/code>.<\/p>\n
