How to convert PNG to WebP online
One PNG or a folder's worth of images. The same three steps work for both.
Let your browser work
Each PNG becomes a WebP with its transparency intact. Adjust quality or dimensions in the conversion settings, then apply them to your batch.
Preview and download
Compare the preview and file sizes before saving. Download individual WebPs or all converted images together as a ZIP.
Why convert PNG to WebP?
PNG is exact but heavy. WebP keeps the transparency, plays in every modern browser, and often drops most of the weight. The honest catch: this converter encodes lossy WebP, so pixels are approximated and source metadata is dropped.

Photos
Lossy mode, fast to load.
Logos & icons
Alpha channel stays.
Screenshots
Fine text can smear.
Animation
WebP yes, this tool no.
Reality check
AVIF usually goes smaller and its support is close behind. JPEG XL compresses further too, but its support and tooling lag. WebP is the safe default.
| What changes | PNG | WebPfrom this tool |
|---|---|---|
| Transparency | Kept | Kept |
| Pixels | Exact, always | Lossy, even at 100% |
| File size | The baseline | Usually smaller, sometimes bigger |
| Metadata | EXIF, GPS, and profiles stay | Stripped |
| Animation | Animated PNGs play | Not supported |
PNG to WebP questions
What happens to file size, transparency, and your original images.
Is this PNG to WebP converter free?
Yes. Convert PNG images to WebP for free, without an account or watermark. You can download each result separately or save the batch in a ZIP.
Can I batch convert PNG to WebP?
Yes. Add up to 100 PNGs at once, with a maximum of 50 MB per file and 200 MB of source files per batch. Each source image can have up to 40 megapixels. Your device's memory may limit large batches. The same quality and resize settings apply to every image.
Does WebP keep a PNG's transparent background?
Yes. This converter preserves transparent and partly transparent pixels. Use the preview's checkerboard background to check the edges of a logo, icon, or cutout before downloading.
Can I convert JPG to WebP or WebP to PNG here?
This tool currently converts still PNG images to WebP only. JPG input, WebP to PNG conversion, and animated PNGs are not supported.
Are my images uploaded anywhere?
No. Your browser reads the files and converts them locally. There are no image uploads, analytics, or remote processing. Closing the tab clears the images.
Does conversion change my original PNGs?
No. The converter creates new WebP files for you to download. Your originals stay as they are, and transparent backgrounds stay transparent.
Will the WebP always be smaller?
Often, but not always. Small PNGs can produce larger WebPs. Each result shows the actual file sizes. Lower the quality or resize the image if you need a smaller file.
Can I convert animated PNGs or use lossless encoding?
Animated PNGs are not supported. This converter uses the browser's native encoder, which does not expose a lossless mode. Even 100% quality is lossy. Source EXIF, GPS, text metadata, and color profiles are not copied.
