Convert your JPG images to WebP in seconds. JPG produces small files that are ideal for photos, but it is lossy and cannot store transparency — transparent areas are filled with white. WebP usually beats both PNG and JPG on file size at the same visual quality and supports transparency, which makes it excellent for the web.
WebP keeps quality high while making files smaller, which is great for faster-loading websites.
How to convert JPG to WebP
- Add your JPG file. Drag and drop your JPG file onto the box, or click to browse.
- Output is set to WebP. The format is already set to WebP. Change it if you need a different output.
- Download. Click Convert and your WebP file downloads automatically.
JPG vs WebP
JPG is small files, lossy, no transparency — best for photographs and detailed images where a small file size matters more than pixel-perfect quality. WebP is modern, small, supports transparency — best for web images that need a small file size while keeping transparency.
Is it private?
Your JPG files are converted entirely inside your browser. Nothing is uploaded to a server, so your images stay completely private — and conversion is instant, even offline.
