Is my file sent to a server?

No. All processing happens entirely in your browser. Your images are never uploaded to any external server, so private photos stay on your device.

WebP is an image format developed by Google. It can make files smaller than JPEG at comparable quality and supports transparency like PNG. Every major browser supports it today.

Will the image quality degrade?

Converting to WebP uses lossy compression, so there is a slight quality reduction. Even Standard usually looks the same to the eye; choose High quality if you want to keep more fine detail. Converting WebP to PNG is lossless.

How many files can I convert at once?

Select as many as you need and convert them in one go. There is no fixed cap on how many files or how large they are; it depends on your device's memory. There is no sign-up and no daily limit.

Is transparency preserved?

WebP supports transparency, so PNG → WebP conversion preserves it. When converting WebP → JPG, transparent areas become white. To keep transparency, choose PNG as the output format.

Can I convert animated GIFs?

GIF files are supported, but for animated GIFs only the first frame is converted.

Should I convert WebP to PNG or JPG?

PNG if the image has transparency or crisp edges, such as a logo, an icon or a screenshot. JPG for photographs, where the file will be far smaller and the difference is hard to see.

Why do images I save from websites come out as WebP?

Many sites deliver images as WebP to load faster, and the browser saves the file exactly as it was delivered. The image itself is fine. It only needs converting if the program or form you use does not accept WebP.

What Is WebP?

WebP is an image format Google released in 2010. It can often keep the same visual quality as JPEG at a smaller file size, which is why it turns up in page-speed advice so often.

WebP supports transparency (alpha channel) like PNG and animation like GIF, combining the strengths of multiple formats in one.

Every major browser now displays WebP, and Google PageSpeed Insights recommends serving images in modern formats such as WebP.
