Is my screenshot uploaded to a server?

No. Your image never leaves your device. The entire mockup is composited using the HTML5 Canvas API running locally in your browser. No data is transmitted anywhere.

What image formats are supported?

PNG, JPG, and WebP images are supported. For best results, use a PNG screenshot at your app's native resolution. The output is always exported as a high-resolution PNG.

What resolution is the downloaded image?

The output width is configurable from 800px to 3200px using the Output Width slider. The default is 2400px — suitable for retina displays, social media posts, and Product Hunt thumbnails.

Can I use this for Product Hunt or Twitter launch assets?

Yes. Use the 16:9 ratio preset for YouTube thumbnails, 1:1 for Product Hunt, or OG 1200×630 for Open Graph cards. Pick a gradient background, add a badge, and download the PNG.
