What this webp converter does
WebP Converter handles both directions: modernise JPEG and PNG files by converting them to WebP, or make WebP files usable in older software by converting back to JPEG or PNG. WebP typically produces files 25–35% smaller than JPEG at comparable visual quality for photographs, though the exact saving depends on the image.
Conversion uses the browser's canvas encoder. Animated WebP files are not supported — only the first frame is converted — and the tool tells you when it detects an animation so you are not surprised by the output.
Why use it
- Reduce image weight on a website without visible quality loss.

Common mistakes
- Using WebP lossless for photographs, which can be larger than JPEG.
- Converting an animated WebP and expecting motion to survive.
- Delivering WebP without a fallback to very old clients; modern browsers all support it, but some email and document tools do not.
Frequently asked questions
Is WebP supported everywhere?
All current major browsers support WebP. Some desktop publishing and email clients still do not, which is why conversion back to JPG exists.
Is WebP always smaller?
For photographs, usually. For simple graphics, a well-optimised PNG can be smaller. Compare the reported sizes.
Does transparency survive?
WebP and PNG support transparency. JPEG does not, so transparent pixels are flattened.
