PNG TO WEBP CONVERTER
Convert PNG images to WebP in your browser — transparency preserved, batch supported.
Lossless ignores quality slider

Smaller PNGs Without Losing Transparency
PNG is lossless, which makes it honest but heavy — a screenshot or a logo with a transparent background routinely costs several hundred kilobytes. WebP supports the same alpha channel but compresses far harder, so the transparency survives while the file shrinks. For interface assets and logos, lossless WebP typically lands 20-30% below the PNG; switching the quality slider off lossless takes it much further again when the image is photographic.
Nothing Leaves Your Device
This tool runs entirely inside your browser. Your image is never uploaded to a server, which means it is also never queued, logged, or retained — and the tool keeps working with your network disconnected.
Key Features
- Alpha channel preserved — transparent PNGs stay transparent
- Lossless mode for logos and UI assets, quality slider for photographic PNGs
- Convert a whole folder at once and download the results as a ZIP
- Runs on the canvas API in your browser — nothing is uploaded
