Frequently asked questions
What is WebP?
WebP is a modern image format that provides efficient compression while supporting high-quality color and transparency.
Will WebP reduce image quality?
WebP uses adjustable lossy compression. At the default 80% setting, most images keep excellent visual quality while becoming much smaller.
Are my images uploaded to a server?
No. Your image is decoded and converted locally by your browser. It is never uploaded or stored by WebP Quick.
Does PNG transparency remain?
Yes. When your PNG contains transparent areas, the browser preserves its alpha channel in the resulting WebP image.
What is the maximum file size?
You can convert one JPG, JPEG or PNG image up to 10 MB at a time.
Why is my WebP file sometimes larger?
Some source images are already highly optimized. If the WebP is larger, lower the quality setting and convert it again.
