About JPG and WebP
JPG is the default format for photos from cameras, phones and stock sites. It opens everywhere, but it is no longer the lightest option for the web. If your blog, online store or portfolio serves dozens of JPG photos, every page loads more data than it needs to, and PageSpeed Insights keeps telling you to "serve images in modern formats".
WebP is that modern format. Google designed it to replace JPG on websites, and every current browser shows it, Safari included. A WebP photo usually weighs a quarter to a third less than the same JPG and looks the same on screen, so your pages load faster on phones and slow connections.
This converter turns your JPG photos into WebP on your device. Drop one photo or a whole batch, and download the results one by one or as a ZIP. Nothing is uploaded, which matters for client shoots and personal photos.
Before you replace your JPGs
The converter saves WebP at quality 80. Your JPG already lost some detail when it was saved, so each new compression removes a little more. Convert from the best copy you have, not from a JPG that has been resized and saved many times.
The WebP keeps only the picture. Camera model, date and GPS location stay behind in the JPG, so the WebP is safe to post publicly.
Keep the JPG for printing, email attachments and older software. Some desktop apps and print services still do not open WebP files.
Questions and answers
Is it safe?
Yes. Conversion happens in your browser, and your photos are never uploaded.
How much smaller will the WebP be?
Usually a quarter to a third smaller than the JPG. Large photos straight from a camera or phone can shrink by half.
Will the photo lose quality?
A little. The JPG is already compressed, and WebP compresses it again at quality 80. At normal viewing size the difference is hard to see.
Are date and location kept?
No. The WebP keeps only the picture, so camera data, date and GPS location from the JPG are left out. That is useful before you publish photos online.
Does it work in Safari?
Yes. Safari cannot save WebP on its own, so the page loads a small encoder into your browser the first time you convert. The photo still stays on your device.
