Convert JPG to WebP

WebP usually produces a noticeably smaller file than JPG at comparable quality, which makes it a good fit for web pages. It is supported by all current browsers.

When to convert JPG to WebP

Faster page loads

Smaller images mean less to download, which is one of the more reliable ways to improve a page load time.

Same picture, fewer bytes

WebP typically reaches a similar visual quality to JPG in less space.

Broad browser support

Chrome, Edge, Firefox and Safari all display WebP.

Where the conversion happens

This converter runs in your browser using its built-in image support. Your file is read from disk, converted, and offered back for download — in the normal case it never leaves your device, so there is nothing for us to store, and the conversion works the same whether the file is 50 KB or 50 MB.

Very large images can exceed what a browser tab can safely decode. If that happens, or if your browser cannot produce WebP files, CurePDF will say so and offer to process the image on our servers instead — but only after you explicitly agree. Nothing is uploaded before you choose that.

Frequently asked questions about JPG to WebP

How much smaller will the WebP be?

Usually noticeably smaller than the JPG at comparable quality, but how much depends entirely on the picture. Rather than promise a figure, the tool shows the real before and after sizes when it finishes, so you can see what your own image actually saved.

Does converting JPG to WebP lose quality?

A little. Both formats are lossy, so this is a second round of compression on an image that has already been compressed once. It is done at 90% quality, which is usually hard to distinguish — but keep the original JPG if you might need to re-edit later.

Where can WebP still cause problems?

Every current major browser handles it. The friction is outside the browser: some older desktop applications, a few operating-system preview panes, and certain upload forms still reject WebP. If you hit one, convert back with the WebP to JPG tool.

Will an animated image stay animated?

No. Only the first frame is converted, and the result is a still image.

Should I convert to WebP or just compress the JPG?

If the file has to remain a JPG — an upload form, or someone else's software — use Compress Image. If it is going on a web page whose markup you control, WebP generally gives you a smaller file at the same quality.
