About this tool
PNG is lossless and supports alpha transparency. WebP also supports transparency and offers both lossless and lossy modes. The browser canvas quality setting generally asks for lossy WebP; this can shrink photographs substantially, while thin text, hard edges or flat-color art may show artifacts at low quality.
Inspect transparent edges against a contrasting background. If exact pixel fidelity is important, retain the PNG or use a lossless workflow rather than lowering quality.
How to use it
- Choose a PNG file.
- Adjust WebP quality and optional dimensions.
- Review transparent areas and file size, then download the .webp result.
Frequently asked questions
Will transparency remain?
Yes. WebP supports alpha and the browser canvas encoder preserves transparent pixels in this conversion.
Is PNG to WebP lossless?
Not at the quality setting used here. The browser encodes lossy WebP; visually inspect the result or keep the PNG for exact pixels.
