What is WebP?
WebP is an image format created by Google for the web. It supports lossy and lossless compression, transparency and animation, and usually makes files 25–35 % smaller than JPG or PNG at the same visual quality. WebP is best for fast-loading websites, online shops and blogs. Older software, some print services, Windows Photo Viewer in older versions, many desktop design tools and some upload forms still refuse WebP files.
What is JPG?
JPG (also written JPEG) is the most widely supported photo format. It uses lossy compression tuned for photographs, which keeps files small, but it has no transparency. JPG is best for photos, e-mail attachments, social media and any upload form.
When should you convert WebP to JPG?
- A website, government form or job portal rejects .webp and asks for a JPG.
- You want to print photos saved from the web, and the print shop only accepts JPG.
- You need the smallest file that every phone, computer and app can open.
Tips for the best result
JPG has no transparency, so transparent areas of the WebP are filled with the background colour you choose (white by default). A quality of 85–92 % gives JPGs that look identical to the WebP.
