Why convert JPG to WebP for your website
Images are often the heaviest part of a web page. Smaller images cut loading time and data use, and loading speed is part of how Google looks at page experience.
WebP uses newer compression than JPG, so at similar visual quality the file is usually smaller. The exact saving depends on the picture. Busy, detailed photos shrink less than smooth ones, such as a clear sky or a plain studio backdrop.
WebP can also hold transparency, which JPG cannot. That lets you use one format for both photos and graphics across your site.
Choosing the right quality setting
| Quality | Good for |
|---|---|
| 90 to 100% | Portfolio pieces, product zoom, photography |
| 75 to 89% | Blog posts, shop listings, most web pages |
| 50 to 74% | Thumbnails and background images |
Test one image at two settings and compare them at the size they will appear on your page. If you cannot spot a difference, keep the smaller file.
Pixel size matters as much as quality. A 4000 pixel photo shown in an 800 pixel column wastes bandwidth. Use Resize Image first, then convert.
When it is better to keep JPG
WebP is great on the web, but JPG is still the safer choice for printing, email attachments and older desktop software. Some online forms and photo labs still reject WebP files. Keep your original JPG files as a backup.
If someone cannot open a WebP image you sent, the WebP to JPG converter turns it back in a few seconds. For graphics with transparency, start from PNG and use PNG to WebP instead.
A practical setup is to keep JPG originals in your archive and publish WebP copies on the site. If your CMS or an image plugin already creates WebP versions on its own, you may not need to convert by hand at all, so check that first.
