Favicon and Manifest Generator
Generate a favicon preview, Web App Manifest, and HTML link tag from a local image.
How to Use the Favicon and Manifest Generator
The Favicon and Manifest generator processes input only in the current browser; it does not upload, access the network, or store user data.
Input content
Select a local PNG, JPEG, or SVG, then enter the site name and theme color.
Select a processing method
Check the dimension preview and clean the scripts, events, and external references in SVG.
Check and export
Copy manifest/link text or download the local icon result.
Limitations and Notes
- Only local files are processed. SVG is securely cleaned up; complex animations and external resources are not retained.
- Different browsers support different icon sizes and manifest fields; validation on the target site is still required.
- The tool only provides locally processed results; important configurations, secrets, documents, and published content must still be reviewed in the target environment.
FAQ
Will the input be uploaded to a server?
No. The page only uses browser memory, the local file API, and local resources already provided with the site.
Why were scripts in SVG deleted?
Scripts and external resources expand the security boundary; the generator retains only static content that can serve as local icons.
Why do the results still require manual review?
Edge-case syntax, regional standards, third-party readers, and target runtime environments may differ; the tool does not replace final validation.
