WebP and JPEG
JPEG and WebP both describe photographs with lossy compression. PNG is the other common file: lossless, often larger, and the right choice when edges and transparency matter. The useful question is which file you can publish, not which extension is fashionable.
JPEG
JPEG is the default language of cameras and of forms that have not been updated. It has no transparency. A quality near 80 is a reasonable photo. Pushing it near the bottom of the Cretivkit slider saves more bytes and softens hair, foliage, and text.
WebP
WebP can be smaller than JPEG at a similar looking photo, and it can keep transparency when you convert from PNG. Support for displaying WebP is broad in current browsers. Support for creating WebP inside a canvas is not the same feature. Cretivkit checks the second one and refuses to label a download as WebP when the browser did not produce that type.
When to stay with JPEG
- The place you are uploading still rejects WebP.
- You need a file that old software will open without a conversion step.
- This browser cannot encode WebP. Use the compressor and keep JPEG.
When WebP is worth the extra file
- You control the website and can serve WebP to current browsers.
- A PNG illustration is heavier than it needs to be and does not require later pixel editing.
- You compared the two downloads and the WebP is actually smaller at a preview you accept.
Conversion does not invent detail. A soft JPEG stays soft as WebP. Make the format decision after looking at both measured sizes, then keep the file that fits the page.
