Use a square source
Start with a centred square image to avoid unexpected cropping.
Photo & Image Tools Pro
Favicon Generator
Turn one square logo into a downloadable favicon package containing a multi-size ICO file, browser PNG icons, an Apple Touch Icon, Android icons and a starter web manifest. Processing happens locally, and the original image remains unchanged.
Create a production-ready favicon package
The source is centre-cropped to a square and processed locally. Use a simple mark with generous padding so it remains clear at small sizes.

How to use Favicon Generator reliably
Follow this four-step process to create a usable output, verify the result and preserve the original file as a master copy.
- 1Select a supported image from your device.
- 2Choose the available output settings for the destination.
- 3Preview the result and inspect dimensions, quality and transparency.
- 4Download the new copy while keeping the original separately.
Practical image workflow
Design for recognition at very small sizes
A favicon is not a miniature poster. Use a simple symbol, strong contrast and generous spacing so the mark remains recognisable in browser tabs, bookmarks and mobile shortcuts.
Simplify detail
Remove tiny text and fine decoration that disappears at 16 or 32 pixels.
Test contrast
Preview the icon against both light and dark browser themes.
Image engineering
Choose settings based on pixels, compression and colour
Image tools work with pixel dimensions, colour channels, metadata and format-specific compression. A smaller file can come from fewer pixels, stronger compression, reduced metadata or a more efficient format. These choices affect sharpness, transparency, colour consistency and future editability in different ways.
Pixel dimensions
Width and height determine on-screen detail and usually have the largest effect on file size.
Lossy vs lossless
Lossy formats discard visual information; lossless formats preserve exact decoded pixels but may remain larger.
Alpha transparency
PNG and WebP can store transparent pixels, while JPG replaces them with a solid background.
Colour and metadata
ICC profiles, EXIF orientation and camera metadata can affect appearance, rotation and privacy.
What the operation can change
- Resizing permanently changes the number of pixels in the exported copy.
- Lossy compression can create ringing, blocking or blurred fine detail.
- Format conversion may remove transparency or metadata.
- Repeated JPG saves can accumulate quality loss.
Domain-specific verification
- Compare the output at 100% zoom rather than only as a thumbnail.
- Inspect text edges, gradients, skin tones and transparent areas.
- Confirm width, height, file size and orientation.
- Test the final image in the website, marketplace or document where it will be used.
Engineering review
Prepare, verify and troubleshoot the image
Before processing
- ✓ Keep the original file as the master copy before editing or conversion.
- ✓ Confirm the source dimensions, colour mode, transparency and orientation.
- ✓ Remove confidential metadata when the image will be published or shared externally.
After downloading
- ✓ Inspect text, faces, logos, gradients and transparent edges at 100% zoom.
- ✓ Confirm the pixel dimensions and file size match the destination requirements.
- ✓ Open the downloaded file in the target browser, CMS, document or application.
ProblemPractical check
The result looks blurredAvoid enlarging a small raster source and reduce compression strength.
The file is still too largeReduce pixel dimensions before applying stronger compression.
Colours or transparency changedUse a format that supports the required alpha channel and test the result on its final background.
Implementation notes
- • Browser image processing is constrained by device memory, especially for high-resolution photographs.
- • Lossy formats discard image information; repeated exports can accumulate visible artefacts.
- • Visual quality should be judged at the final display size rather than only from the compression percentage.
Verify the output before using it
- ✓ Preview at 16×16 and 32×32
- ✓ Check the symbol remains centred
- ✓ Confirm transparency looks intentional
- ✓ Test the favicon in a real browser tab
Technical limitations
- • A generated PNG is not a complete multi-size ICO package
- • Fine text is usually unreadable
- • Browser caching can delay favicon updates
