Frequently Asked Questions

How does the canvas generator achieve high image sharpness?

We render the HTML5 Canvas with a 2x retina device pixel ratio multiplier (up to 2400x1350 pixels). When scaled down for social media, text and code lines remain crisp without blurry edges.

Are images generated on a remote server?

No. The entire rendering cycle runs on your device's GPU and CPU through the browser Canvas 2D API. Your text and images are completely private.
