A practical guide to creating common favicon and app-icon sizes locally using Favicon Generator.

Quick answer
Use the Favicon Generator to produce common favicon and app-icon sizes locally by uploading a source image, choosing the desired output variants, and downloading the generated files for use on your website or app.
Why create favicons and app icons locally
Favicons and app icons help users identify your site or app in browser tabs, bookmarks, and home screens. The Favicon Generator tool generates common favicon and app-icon sizes locally, letting you produce the standard images you need without relying on an external service. This short guide explains a straightforward, privacy-conscious workflow for preparing a source image, generating the icon set, and integrating the outputs into your project.
Because the tool works locally, you retain control of your original artwork files and the generated icons, which is useful when you must handle brand assets carefully or work without an internet connection. The instructions here focus on practical steps that work for designers and developers who need a quick, reliable favicon and app-icon package.
Prepare a suitable source image
Start with a single high-quality square image that clearly represents your brand or app. A square canvas preserves aspect ratio across the various output sizes that favicons and app icons require.
If you have an SVG, vector formats are ideal because they scale crisply. If you only have a raster image, use a high-resolution PNG or JPEG and crop it to a square before generating icons. Keep the main graphic or mark centered and leave a small visual margin so important details do not get clipped at smaller sizes.
Name your source file clearly so you can identify it later when integrating output files into your site or app. Save a backup of the original artwork before making edits.
Generate favicons and app icons with the tool
Follow these practical steps using the Favicon Generator to produce the common icon sizes you need. The tool generates common favicon and app-icon sizes locally, so your files remain on your device during processing.
- 1
Open the Favicon Generator
Go to the Favicon Generator route from this tutorial and start a new project. The generator is designed to produce the common favicon and app-icon sizes locally.
- 2
Upload your prepared source image
Select the square image you prepared earlier. If the tool accepts vector inputs and you have an SVG, choose that to preserve sharpness across sizes. Confirm the file is the correct one before continuing.
- 3
Choose output variants
Select the favicon and app-icon variants you need for your project. The generator creates the standard set of icons used by browsers and mobile platforms. Only choose the variants you will actually use to keep the download package tidy.
- 4
Adjust optional settings if available
When present, use the tool’s optional settings to tweak background fill, padding, or visual alignment. These adjustments help the icon look balanced at small sizes and when placed on different backgrounds.
- 5
Generate and review the results locally
Trigger the generation process. The tool will create the requested output files locally. Review the generated images on your device to confirm visual clarity and correct cropping at multiple sizes.
- 6
Download and organize the files
Download the generated icon package and extract it to a clear folder within your project. Use consistent names for files and keep a copy of the original source artwork alongside the generated set.
- 7
Integrate icons into your project
Add the favicon and app icons to your website or app according to your platform’s recommended markup and asset locations. Place each generated file where your site or app expects icons to be so browsers and operating systems find them automatically.
What to expect after generation
After completing the generation process you will have a set of image files in the output folder. These typically include the small browser favicon and larger app-icon sizes that mobile platforms use. Because the Favicon Generator creates common favicon and app-icon sizes locally, you will receive files that are ready to add to your project without further resizing.
Inspect each file at its intended display size to confirm legibility. Use browser developer tools or a file preview to check how the icons appear against light and dark backgrounds. If you need to refine contrast or padding, return to your source image and repeat the generation workflow.
Keep the generated icon package with your project assets and maintain the original source artwork for future updates or platform-specific adjustments.
Privacy and local processing
The Favicon Generator operates locally to produce common favicon and app-icon sizes. Local processing means the images you upload for generation remain on your device during the conversion steps, which reduces exposure of brand assets to third parties. This local workflow is helpful when you want tight control over confidential or trademarked materials.
Always verify where a tool stores files on your device and whether it leaves temporary files in system folders. After you finish, remove any temporary files you do not need and keep secure backups of final assets in your project repository or version control system.
Troubleshooting common issues
If the generator reports a file format error, confirm your source image is a supported format such as SVG, PNG, or JPEG. For raster images, ensure the file is not corrupted and that the canvas is square or can be cropped to square without losing essential detail.
If generated icons appear blurry at small sizes, revisit the source artwork and simplify details or increase contrast. Vector source files usually avoid blurriness because they scale cleanly.
If a particular variant is missing from the output, check the selected output options before generation. If integration problems occur after download, verify that files are placed in the correct project folders and that your site or app references the correct filenames.
When you encounter unexpected behavior with the tool itself, reload the page and retry the process. If problems persist, document the steps you took and the exact error text so you can reproduce the issue for reporting or further investigation.

Frequently asked questions
What kind of source image should I use for best results?
Use a square source image with a clear, centered graphic. Vector formats such as SVG are ideal for crisp scaling. For raster images, use a high-resolution PNG or JPEG and crop to a square canvas, keeping important details away from the edges.
Will the tool upload my files to a server?
The Favicon Generator creates common favicon and app-icon sizes locally. Processing happens on your device, which helps keep your source and generated files private.
How do I update an icon later?
Keep the original source file and regenerate the icon set after edits. Replace the generated files in your project and, if necessary, clear caches that may serve old icons so the updated images appear to users.
What if icons look wrong in some browsers or platforms?
Confirm you included the recommended variants for the target platforms and that your site or app links to the correct filenames. Some platforms require additional metadata; consult platform documentation when advanced integration is needed.
