Frequently asked questions
Quick answers about the ConvertKit Lite JPG to WebP tool.
Are my images uploaded to a server?
No. The conversion runs in your browser, so your images stay on your device.
Is WebP smaller than JPG?
Usually, yes, often by a quarter or more at similar quality. The result depends on the image, and the size shown next to each file is the real one.
Does WebP work everywhere?
All current major browsers display WebP. Some older software and apps may not open it, so keep your originals.
Does it keep transparency in PNG files?
Yes. Transparent PNG areas stay transparent in the WebP file.
Why is a WebP file sometimes bigger?
An already heavily compressed JPG can grow when converted at high quality. Lower the quality slider or limit the width.
