About Compress WebP
Convert and compress JPG, PNG, HEIC or existing WebP images into compact WebP files. WebP usually beats both JPEG and PNG on size at the same visual quality and also supports transparency, which makes it a strong choice for website images.
When it helps
- Optimizing hero images and product photos to improve page speed scores.
- Replacing heavy transparent PNGs on a site with much smaller transparent WebPs.
- Reducing image storage in a web app or CMS that serves WebP.
Tips
- Quality around 70-85% suits most web photos. Check fine textures like hair or foliage when going lower.
- Resize to the largest size the image is actually displayed at. Combined with WebP, this gives the biggest savings.
- Keep a JPG or PNG original. Some email clients and older desktop apps still don't open WebP.
