Frequently Asked Questions
What image ratio works best?
16:10 screenshots fit the device aperture best, but the tool will still contain non-16:10 images safely.
Does export happen locally?
Yes. Rendering and export happen in your browser with JavaScript and the HTML canvas API.
Can I switch between iMac and MacBook Pro quickly?
Yes. Template and finish controls update instantly while preserving your uploaded screenshot.
