Frequently Asked Questions

Export PNG, JPEG or WebP. Input supports formats your browser can decode, including AVIF. AVIF encoding is unavailable; animated inputs export as a static frame.

JPEG does not support transparency. The tool fills transparent areas with the background color you specify (default white). Set a different background color before converting if you need a different fill.

The default quality of 82 is a good balance between file size and visual quality for most use cases. For web images where file size matters, try 70–80. For archival or print use, 90–95 is safer.
