Why convert PNG to WebP
WebP is designed for the web and can reduce image weight compared with PNG, which helps pages load faster. It also keeps transparency, so logos and cutouts can switch formats.
Typical situations
- Making website images lighter so pages load faster
- Converting a logo with a transparent background without losing the transparency
- Preparing images for a site builder or store that recommends WebP
What to watch for
If your browser cannot create WebP files itself, the converter uses a built-in encoder instead, which can be a little slower. Lossy WebP at low quality can soften fine detail, so compare the result before replacing originals.
Tips for better results
- For logos and flat graphics try quality 90 or higher, because heavy compression shows on solid colors.
- Compare the WebP with the original at full size before you replace anything on a live site.
- Keep a PNG copy for places that still cannot display WebP, such as some older email programs.

Frequently asked questions
Can all browsers show WebP images?
Current versions of the major browsers display WebP. Very old browsers and some older desktop programs may not, so keep the original if you need maximum compatibility.
Are my files uploaded to a server?
No. The conversion runs in your browser using your own device, so the files are not sent to Convert In Place or anyone else. See how it works for a way to check this yourself.
Is there a limit on file size or number of files?
You can use it as often as you like. One batch holds up to 200 files, and each file can be up to 200 MB. Large files and long batches depend on the memory of your device, and phones handle less than computers.
