Free online JPG to WEBP converter

Source format: JPG

JPG (also written as JPEG) is one of the most common image formats for photos and web graphics. It uses lossy compression, which reduces file size by removing some image data. That makes JPG a good choice for photographs, realistic scenes, and images where small file size matters. It is supported by nearly every device, browser, and image editor.

Target format: WebP

WebP is a modern image format developed by Google for the web. It supports lossy and lossless compression, and it can often create smaller files than JPG at similar visual quality. WebP also supports transparency, and it can support animation in compatible workflows. It is widely used for web publishing, faster page loading, and bandwidth reduction.

How to convert jpg to webp

The simplest method is to use an image editor or batch converter that can export to WebP. If you only need a quick conversion, you can convert the file on 101convert.com for free without installing any software.

1. Open the JPG file in a program that supports WebP export, such as GIMP, IrfanView, XnConvert, or Adobe Photoshop with WebP support installed.
2. Choose the export or save option. In many programs this is found under File → Export or File → Save As.
3. Select WebP as the output format.
4. Adjust quality settings if available. For photos, a quality value around 75–85 is often a good balance between file size and appearance.
5. Save the file with a .webp extension.

If you prefer command-line conversion, ImageMagick can do this on many systems. Example: magick input.jpg output.webp. For batch conversion, tools like XnConvert and ImageMagick are especially useful.

Quality and compatibility notes

Converting JPG to WebP can significantly reduce file size, but the result depends on the source image and the chosen quality settings. Because JPG is already lossy, converting it again to WebP does not restore lost detail; it only re-encodes the image in a different format. For best results, start from the highest-quality original available.

Compatibility is excellent in modern browsers and apps, but some older software and legacy systems may not open WebP files. If you need maximum compatibility for email, print workflows, or older devices, keep a JPG copy as well. For editing masters, a lossless source format such as PNG, TIFF, or the original camera file is often preferable.
