Does converting to WebP keep transparency?
Yes. Unlike this site's JPG-output tools, this conversion doesn't force a white background, so PNG transparency is preserved.
Image Tools
Convert an Image to WebP
Convert a JPG or PNG image into the WebP format with an adjustable quality slider, right in your browser.
Why WebP behaves differently here
This converter redraws your image onto canvas and exports it as WebP using an adjustable quality slider from 20% to 95%. Unlike this site's JPG-output tools (Compress Image, PNG to JPG), converting to WebP does not force a white background fill first — WebP supports transparency, so a source PNG's transparent areas are preserved in the output rather than flattened to a solid color.
WebP generally produces smaller files than JPEG at a comparable visual quality, which is why most modern browsers and CDNs prefer it for web images. The trade-off is that a WebP file won't open in every older tool or image viewer the way a JPG or PNG will.
Workflow at a glance
Use this quick flow to understand where the tool fits in your work and what to review before relying on the output.
Review checklist
Before
Confirm the site, app, or platform you're publishing to actually supports WebP images.
After
Compare the new file size against the original and check transparency renders correctly on the real background it will sit on.
When WebP is worth switching to
Use it when you're preparing images for a website and want a smaller file than JPEG at similar quality — especially useful for images that also need to keep transparency, which this site's JPG-focused tools can't do.
Who converts images to WebP
Website owners

What this converter gives you
Quality slider from 20% to 95%
Controls the WebP encode quality, trading detail for file size.
Transparency preserved
Unlike this site's JPG conversions, a source PNG's transparent areas carry over to the WebP output.

Either common format can be the source for the conversion.
Canvas-based, runs locally
The conversion happens entirely in your browser tab.

Where WebP pays off
Converting a page's hero image to WebP for faster loading.
Shrinking a transparent logo or icon without losing its transparency.
Preparing smaller assets for a site or app that already supports WebP.
Comparing WebP output size against the original JPG or PNG before deciding which to publish.
Where the conversion happens
The conversion happens entirely on an HTML canvas in your browser — the image is never uploaded to a server.
Getting a good result
- Use this specifically when you need both a smaller file and preserved transparency — that combination is unique to WebP among this site's image formats.
- Confirm the destination (website, app, or platform) actually supports WebP before replacing your only copy of an image.
- Compare a couple of quality settings for important images rather than assuming the default works for everything.
- Keep the original JPG or PNG in case you need a format with broader compatibility later.
WebP conversion mistakes to avoid
Assuming every platform accepts WebP
Some older tools, email clients, and platforms still don't display WebP images correctly.
Not testing transparency on the actual destination
Confirm the transparent WebP looks right against the actual background color it will sit on.
Treating this the same as the JPG tools
Unlike Compress Image or PNG to JPG, this conversion keeps transparency — don't expect a forced white background.
Skipping the size comparison
Always check the resulting file size — WebP's benefit varies depending on the source image's content.
Before you publish WebP images
WebP Converter is the tool on this site to reach for when you need both a smaller file and preserved transparency. Confirm your destination supports WebP first, since compatibility is the one trade-off against its size and quality benefits.
