How to use Convert to WebP
- Add the JPG or PNG images you plan to publish, up to 20 at a time.
- Leave Convert to on WebP, which is where this page opens.
- Set the quality, then select Convert.
- Compare the reported sizes and download the WebP files that suit the page.
Example: Convert to WebP
A large photograph that needs a lighter copy for a web page.
Options
- Convert to
- The page opens on WebP because web delivery is the job here, and WebP keeps transparency. The list still offers JPEG and PNG when a different target is needed.
- Quality for JPEG and WebP
- Start at 0.9, then compare the detail against the file size. Lower values shrink the file and soften fine edges first.

Where a WebP copy helps
A WebP file can cut the bytes a page has to send, but only when the converted file is actually smaller, and only the result line can tell you that for your image. Quality matters more than format on photographs: a low-quality WebP can look worse than a good JPG at a similar size. Keep the original file as well, especially when a print service or an older program will need to open it later.
Questions about Convert to WebP
Will a WebP file open everywhere?
Every current browser shows it, which is why it suits a web page. Older desktop programs and some print services still cannot, so keep the JPG or PNG alongside the WebP when the file has to be opened elsewhere.
Does WebP keep transparency?
Yes. WebP stores an alpha channel, so a transparent PNG logo converts without a background color and stays transparent. That is the main difference from the JPEG target.
What quality should I choose?
Start at 0.9 and compare how the image looks with how large the file is. A lower value can save a useful amount of space but softens fine detail.
What if I add a WebP file?
It is refused with a message, because this page prepares JPEG and PNG images for the web rather than re-encoding a file that is already WebP. Use the WebP to JPG or WebP to PNG page for that file.
Can I turn WebP back into JPG or PNG?
Yes. The WebP to JPG and WebP to PNG pages use the same converter with a different target, so a round trip works when another program insists on those formats.
