What this tool does
Generate common favicon and app-icon PNG sizes from one source image, choose contain or cover fitting and a background color, preview results and download a ZIP.
People often describe this task with phrases such as favicon generator, app icon generator, favicon png sizes and website icon maker. This page uses those terms only where they refer to the same underlying function.
How to use the Favicon & App Icon Generator
- Open the Favicon & App Icon Generator page and select or enter the source data required by the tool.
- Review the available controls instead of accepting defaults blindly when the destination has a size, format, layout or compatibility requirement.
- Run the operation and inspect the preview, status or generated result before treating it as final.
- Download or copy PNG icon set, ZIP and verify it in the destination application, browser, viewer or workflow that will actually use it.
Use the interactive tool above for the actual operation. The documentation below explains what the controls mean, what changes in the file/data, and how to troubleshoot common results.

- Output: multiple PNG icon sizes in ZIP
How it works technically
Raster image operations work on decoded pixel data. Dimensions, alpha transparency, color representation and encoder settings can all affect the result independently.
Icons are usually square raster assets. Scaling one source into many fixed sizes creates separate pixel grids optimized for different UI contexts.
Contain keeps the whole source and may add background; cover fills the square and may crop edges.
Common use cases
- Create favicon image sizes
- Prepare Apple touch icon dimensions
- Prepare common PWA/app icon sizes
- Generate a consistent icon set from a logo
Choosing the right settings
- Start from a large, simple square logo.
- Check the 16×16 and 32×32 previews because tiny sizes often lose detail.
Common problems and fixes
The favicon looks blurry
Use a high-resolution, simple source and avoid fine text/details that cannot survive at 16×16 pixels.
Browser processing and privacy notes
The source code for this build performs the documented file transformation or analysis from browser JavaScript/Web APIs, and the video tools load FFmpeg.wasm for media processing. The site also contains third-party analytics, font/CDN and advertising scripts that can make ordinary network requests. Therefore, the precise claim made here is limited to the tool routine: it does not need a separate AutoClip file-upload API in order to perform the documented local operation.
For sensitive files, you should still use your browser’s developer tools or network controls if you need to independently verify the behavior of every third-party request in your environment.
Frequently asked questions
What does the Favicon & App Icon Generator do?
Generate common favicon and app-icon PNG sizes from one source image, choose contain or cover fitting and a background color, preview results and download a ZIP.
What input and output does it use?
Input: one image, preferably square Output: multiple PNG icon sizes in ZIP Outputs include PNG icon set, ZIP.
Do I need to install desktop software?
No desktop installation is required for this page. The interactive workflow runs from the web browser. Some advanced media features load browser-side JavaScript/WebAssembly libraries when needed.
Are selected files processed through the tool interface?
Yes. The implementation reads selected files with browser APIs and performs the documented transformation or analysis in the page. External libraries, analytics and advertising scripts may make their own network requests, so this statement is about the file-processing routine itself.
The favicon looks blurry?
