What this favicon and app icon resizer does
Create common square PNG icon sizes from one source image. The tool packages the selected sizes into a ZIP file and includes a simple site.webmanifest that points to those PNG files. It is useful when preparing a small icon set for a website, PWA prototype, app shortcut, or design handoff.
This workflow exports PNG files. It does not promise an ICO binary because browser Canvas APIs do not create every ICO variant consistently. If a platform specifically requires an ICO file, use its documented conversion step after downloading the PNG pack.
How to create an icon pack
- Upload a square logo, illustration, or other image with clear subject edges.
- Select the PNG sizes you need, such as small browser icons, shortcut icons, or larger app icons.
- Choose Create & Download.
- Open the ZIP file and review each icon at its actual size. Small icons may need a simplified logo or higher contrast.
Preparing a good source image
Start with a sharp image that has enough detail for the largest selected size. A square source avoids unexpected cropping. Keep important marks away from the outer edge because some browsers and operating systems display icons with their own masks or rounded shapes.
What is inside the download
The ZIP contains one PNG for every checked size, using names such as icon-192x192.png, plus a site.webmanifest with matching icon entries. The manifest is a starting point for a web project; review its name, start URL, display mode, and other site-specific values before publishing it.
Privacy and file handling
The source image is processed locally in the browser. The PNG files and manifest are assembled into a ZIP on your device. No account or image upload is required for this workflow.
Frequently Asked Questions
Does this tool create an ICO file?
No. It creates PNG icon sizes and a web manifest. Use the PNG pack directly when the destination accepts PNG, or convert it with a platform-specific tool when an ICO file is required.
Which icon sizes should I choose?
Choose the sizes required by your site or app. Selecting only the sizes you need keeps the download smaller and makes the asset handoff easier to review.
Does the tool make a low-resolution image sharper?
Resizing can change the pixel dimensions, but it cannot recreate detail that was not present in the source. Use a clear, high-resolution source and inspect the smallest icon before publishing.
