Convert PNG to WebP
WebP is the practical middle ground PNG users have wanted for years: it keeps transparency, but compresses like a modern codec. For web images, converting PNG to WebP routinely cuts file size by half or more with no visible difference.
This page runs the local image converter preconfigured for WebP output. Transparency in your PNG carries straight through — no background fill needed.

How it works
Select one or more images.
Choose the target format; consequences (like losing transparency in JPEG) are shown before converting.
Pick a background color if converting transparency to JPEG.
Convert and download individually or as a ZIP.
What the tool does
- PNG, JPEG, and WebP output
- Batch conversion with per-file success/failure isolation
- Explicit background selection when alpha meets JPEG
- Quality control for lossy targets
- ZIP download with deterministic file naming
How the result is verified
Every output is re-decoded to confirm it parses as the target format with the expected dimensions; failures are isolated per file.
Frequently asked questions
Does WebP keep my transparency?
Yes. WebP supports an alpha channel, so transparent PNG areas stay transparent — no background color is required.
Lossy or lossless — which does this produce?
The quality slider controls a lossy encode, which is what gives WebP its size advantage. At quality 90+ the difference from the PNG is imperceptible for most images.
