Frequently asked questions
Are source images uploaded?
No. Image decode, Canvas rendering, diagnostics and packaging run in this browser.
Is the favicon.ico file valid?
Yes. It is an ICO container with PNG-backed 16, 32 and 48 pixel entries supported by modern browsers.
What is the maskable safe zone?
The preview follows the W3C app manifest model in which important content should fit inside a circle with radius 40 percent of icon size.
Can it audit a live site?
It audits pasted manifest JSON locally. Static Cloudflare Pages deployment intentionally does not crawl arbitrary cross-origin sites.
