Why so many saved images are WebP files
WebP is an image format Google introduced in 2010 to make web pages lighter. It supports lossy and lossless compression, transparency and animation, and Google’s own tests found lossy WebP images 25 to 34% smaller than JPGs of comparable quality. That’s why search results, online shops and news sites now send so many pictures as WebP, and why the image you just saved has a .webp extension.
Every current browser displays WebP, but other software lags behind. Older photo editors, some print and photo book services, document templates and the upload forms on plenty of websites still expect a JPG. Converting the WebP file to JPG is the simplest fix, and this converter does it inside your browser, so your files never leave your device. Images saved from the web can also arrive as AVIF; the AVIF to JPG converter handles those.
Before you convert WebP to JPG
JPG suits photos, product shots and anything you plan to print or attach to an email. A few things are worth knowing first:
- Quality. The slider runs from 10 to 100. The default of 92 keeps photos looking like the original; lower values give smaller files but eventually show blocky patches.
- Transparency. JPG has no transparent pixels, so choose a fill color that matches where the image will go: white, black or a custom color. To keep the transparency, save as PNG instead. The JPG to PNG converter accepts WebP files too.
- Animation. An animated WebP becomes a single still JPG made from its first frame.
- File size. WebP compresses more efficiently, so the JPG will usually be somewhat larger than the original. Each result shows the new size and the change.
