Download imageHow to use
- Choose a JPEG, PNG, or WebP image up to 20 MB and 12 megapixels.
- Select WebP, JPEG, PNG, or ICO (favicon) as the output format. Adjust quality for WebP or JPEG; the control does not apply to PNG and ICO. JPEG puts white behind transparent areas.
- Click Convert image. Check the preview and file size, then download the new version using the button below the result.
How it works
JPG does not preserve transparency, and lossy conversions can reduce quality. ICO exports square icons up to 256 pixels; enlarging small images does not recover detail.
Turn a PNG logo with a transparent background into an ICO file containing sizes from 16 to 256 pixels to use as a favicon.
Common questions
Which formats preserve a transparent background?
PNG, WebP, and ICO support transparency. JPG puts white behind transparent areas.
Does converting JPG to PNG improve a photo's quality?
No. Conversion does not recover details already lost to JPG compression and may produce a larger file.
How do I convert PNG to ICO for a favicon?
Choose the PNG and select ICO (favicon) as the output. One file includes 16, 32, 48, 64, 128, and 256-pixel icons. Rectangular images are centered with transparent padding to preserve their aspect ratio. Conversion happens in your browser.
