A PRACTICAL IMAGE GUIDE
Create smaller transparent assets from PNG
WebP output can keep a PNG's transparent background while offering a different size-quality tradeoff. This tool uses quality-based WebP encoding, so compare it with your PNG when crisp text or exact colors matter.
How to convert a PNG to WebP
Choose PNG files; WebP output is selected on this page. Compress with Smart, compare the result, and try another quality if needed. Leave dimension fields empty to avoid optional resizing.
When to keep PNG instead
Keep a lossless PNG when exact pixel values or compatibility matter more than possible savings. Avoid repeated lossy re-exports of a master graphic. A WebP result may be larger than an already-efficient PNG.

Does the transparent background become white?
Not with WebP output. JPEG or BMP output instead replaces transparent areas with white.
