PNG to WebP converter
Keep transparency while creating compact images for modern websites and apps.
Full capability guide
Predictable format conversion
Conversion pages enforce their advertised formats and explain every change made to the output.
Format-aware controls
Quality appears only for lossy JPEG and WebP output; PNG uses lossless encoding.
Transparency and sizing
Choose the JPEG background color, limit maximum width and prevent smaller images from being enlarged.
Naming and duplicates
Build names with {name}, {format} and {index}; duplicate outputs can be numbered or reported as individual errors.
Per-file evidence
Review format, dimensions, metadata policy and visual comparison, then retry or reprocess one file with current controls.

How to convert PNG to WebP
- Add PNG files to the image desk.
- WebP is selected automatically; adjust output quality if needed.
- Convert and download individual files or a ZIP batch.
Why WebP is useful
WebP supports transparency like PNG but can use efficient lossy compression. That usually makes it a better delivery format for website graphics, product cutouts and interface images.
Transparency, quality and file size
Transparent pixels remain transparent in the WebP output. Quality controls the visible color information around the subject, so inspect soft shadows, gradients and edges against both light and dark backgrounds.
A simple logo or flat graphic can already be very efficient as PNG and may not become dramatically smaller. For photographs or complex transparent product images, WebP usually has a clearer advantage. Use the general image converter when you need to compare another output format.
| Image type | Likely best format | Reason |
|---|---|---|
| Flat logo | PNG or WebP | Compare both outputs |
| Transparent product image | WebP | Efficient detail and alpha |
| Photographic graphic | WebP | Lossy compression saves more |
