Frequently asked questions

Are my files uploaded to a server?

Is there a limit on files or size?

We don't set any limits. You can process several files at once; the maximum depends on your device's memory.

If you use 85% quality or higher, the difference is practically unnoticeable. You can raise the quality with the slider before converting.

About this tool

Switching your photos from JPG to WebP is one of the simplest optimizations to make a site load faster, especially on phones.

WebP is usually about 25% smaller than a JPG with equivalent visual quality.

JPG is the most common photo format; it's small but loses some detail. WebP is Google's modern format: lighter than JPG and PNG at similar quality.
