Can BatchMint convert PNG to WebP?
Yes. Static PNG input can be converted to WebP locally, including transparent pixels.
Last reviewed: July 17, 2026
Supported image formats
The current workspace accepts JPEG, PNG and WebP input and outputs JPEG, PNG, WebP or AVIF. JPEG suits photographs, PNG suits lossless graphics, and WebP or AVIF can reduce web delivery size when compatibility fits the destination.
JPEG, PNG, WebP and AVIF compared
The best output depends on the image content and the destination. No format is smallest or highest quality for every image.
| Format | Transparency | Browser compatibility | Good for | Important limits |
|---|---|---|---|---|
| JPEG | No | Near-universal | Photographs and product images | Lossy; transparent pixels require a background color |
| PNG | Yes | Universal | Logos, interface graphics, screenshots and lossless assets | Often much larger than lossy formats for detailed photographs |
| WebP | Yes | Current major browsers | Modern storefront images, photos and transparent assets | Older desktop tools and publishing workflows may have uneven support |
| AVIF | Yes | Current major browsers; verify older clients | High compression when download size matters | Encoding is slower and compatibility outside browsers is less uniform |
Input formats

Transparency
PNG, WebP and AVIF can contain alpha transparency. JPEG cannot contain alpha, so BatchMint composites transparent pixels onto the selected background color before JPEG encoding.
FAQ
Can it open HEIC today?
No. HEIC/HEIF remains a planned beta capability and is not in the current deployed input list.
