Convert JPG to WebP free, in bulk and right in your browser. Make photos lighter for websites, landing pages and blogs without visible quality loss.
PNG is lossless, so quality doesn’t apply. Use Resize to make files smaller, or choose WebP.
Your browser can’t create WebP files, so WebP is unavailable. Try a current version of Chrome, Edge or Firefox.
How it works
Drop up to 30 files, click to browse, or paste from your clipboard.
Move the quality slider and watch the new file sizes update live.
Download each image, or everything at once as a ZIP.
What is JPG?
JPG (or JPEG) is the most widely supported image format in the world. It uses lossy compression, which keeps photos small by discarding detail the eye barely notices. It does not support transparency, and repeated saving at low quality can create visible artefacts around edges and text.
What is WebP?
WebP was developed by Google for the web. It supports both lossy and lossless compression as well as transparency, and typically produces smaller files than JPG or PNG at similar visual quality. It is supported by all major modern browsers, which makes it a strong default for websites and landing pages.
Drop your JPG images into the converter above. They are converted to WebP instantly in your browser, and you can download them one by one or as a ZIP.
Yes, with no watermark and no ads. Use it 3 times without signing up; after that, a free one-time sign-up gives you full access. You can convert up to 30 images at a time. Access is subject to our Terms of Use.
No. Conversion happens entirely on your device, in your browser. Your images are never sent to a server.
At the default quality most people see no visible difference. Use the quality slider and the before-and-after comparison to find the balance you like.
JPG files do not contain transparency, so the result is fully opaque.
