Why this tool is useful
Prepare the common website and installable-app icon files in one repeatable export, including the markup needed to connect them to an HTML document.
Choose a complete, QA-approved edition published for this site.
Build a ready-to-publish ZIP with favicon.ico, browser PNG icons, an Apple touch icon, PWA icons, a web manifest and copyable link markup using only local browser processing.
Ready. Your working data stays in this browser.
Files stay on this device. Processing uses browser APIs only; nothing is uploaded to YTSave, the media API or a proxy.
Prepare the common website and installable-app icon files in one repeatable export, including the markup needed to connect them to an HTML document.
After local image validation, the browser renders every required resolution, assembles a multi-entry ICO, generates a bounded manifest and packages only fresh outputs with pinned JSZip.
Open a square PNG brand mark, enter the site and short names, then download a ZIP that contains favicon files, 180/192/512 icons, site.webmanifest and favicon-links.html.
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
