Why convert JPG to WEBP?

People convert JPG to WEBP because JPG discards a little more detail every time it is saved, and it cannot store a transparent background, while WebP is typically 25–35% smaller than the same picture as JPG or PNG.

How to convert JPG to WEBP

1. Choose your JPG file. Drop it on the box above, or tap to browse. You can pick several files at once.
2. Confirm the target is .webp. It is preselected when your browser can encode it; otherwise the closest available target is chosen. Adjust quality, size or the other options if you want to.
3. Convert and download. Press Convert, then Download. Your file stays on your device the whole time.

What is a .jpg file?

JPG (also written JPEG) is the universal photograph format — small files that open on every device made in the last twenty-five years. It is lossy, discarding detail the eye is least likely to miss, which makes it excellent for photos and poor for screenshots, logos and text, where it leaves visible smudging.

What is a .webp file?

WebP is Google's web image format: roughly 30% smaller than JPG at the same visible quality, with support for transparency and animation. Every current browser displays it, but a great many desktop applications still cannot open one, which is why converting WebP to PNG or JPG is such a common need.

What to expect from this conversion

The image is decoded and re-encoded, so keep the quality slider at 85% or above — at that setting the difference is invisible to the eye. Transparency is flattened onto white for formats that cannot store it, such as JPG.

Is it private?

Yes, by design. Every conversion happens inside your own browser using your device’s processor — there is no server that receives your JPG file, so there is nothing for anyone to store, scan or leak. You can confirm it yourself: open your browser’s developer tools, watch the Network tab while you convert, and you will see no upload.
