WebP is great for the web, but it still isn't supported everywhere — many desktop apps, email clients, print services, and older systems can't open WebP files. Converting to JPG gives you a universally compatible format that works on every device and in every application, from Photoshop to your local print shop.
| File type | WebP | JPG | Note |
|---|---|---|---|
| Web photo (1920×1080) | 420 KB | 620 KB | Larger but universal |
| Product image (2000×2000) | 680 KB | 980 KB | 95% quality |
| Blog thumbnail (800×600) | 85 KB | 120 KB | 90% quality |
Many email clients display WebP as attachments rather than inline images. Convert to JPG to ensure recipients see your images properly regardless of their email app.
Downloaded a WebP image you want to print? Most print services and photo kiosks require JPG. Convert before uploading to your print service.
Older versions of Photoshop, Illustrator, and Office apps can't open WebP. Convert to JPG to work with these images in any software.
If you're saving web images for reference or archival, JPG is the safest long-term format. Every system for decades to come will support it.

There is some quality reduction since JPG uses lossy compression. At 90-95% quality, the difference is invisible to the eye. Files will be slightly larger than the original WebP.
Despite wide browser support, many desktop applications (older Photoshop versions, Office suite, some email clients) don't support WebP. JPG is the safe choice when you need the image to open everywhere.
Usually yes — JPG files are typically 25-35% larger than WebP at the same quality. A 500KB WebP image might become 700-800KB as JPG. The tradeoff is universal compatibility.
