How to convert PNG to WebP
Add your PNG files
Drag and drop one or many PNG images onto the page, or click to browse.
Choose WebP as the output
Select WebP so each image is re-encoded into the lighter, web-friendly format.
Convert and download
Click convert, then save each WebP or download the whole batch as a ZIP.
Why convert PNG to WebP
WebP usually produces noticeably smaller files than PNG while keeping good quality, which helps pages load faster. This PNG to WebP converter re-encodes each image with the Canvas API in your browser, so nothing is uploaded and it works offline once the page has loaded. WebP supports transparency, so an alpha channel from your PNG is preserved.
Converting to WebP re-encodes the image, so the result is not pixel-identical to the original, and Canvas re-encoding drops embedded metadata such as EXIF. If you want to squeeze files down further for the web, pair this with the Image Compressor to tune size and quality.
Frequently asked questions
Why convert PNG to WebP?
WebP files are typically much smaller than PNG at similar quality, which makes web pages load faster while still supporting transparency.
Is transparency preserved when converting PNG to WebP?
Yes. WebP supports an alpha channel, so transparency from your PNG is kept.
Are my PNG files uploaded?
No. This PNG to WebP converter runs locally in your browser with the Canvas API, so files stay on your device.
Can I convert multiple PNG images at once?
Yes. Add several PNGs, convert the batch, and download each WebP or all of them as a ZIP.
Do all browsers and apps support WebP?
Most modern browsers do, but some older apps and editors do not. If something cannot open WebP, convert to PNG or JPG instead.
