Open Compress Images for WebsiteWhat compression means for Core Web Vitals
Smaller files mean faster LCP and less layout shift from slow images. Google's Core Web Vitals and your visitors both reward it: pages under ~1MB load noticeably faster on mobile connections.
A compression workflow for web images
- Open the Compress Image tool.
- Export your design at the exact display size (Retina = 2×).
- Compress to quality 70-85%.
- Ship as WebP when the CMS allows it.
- Always resize before compressing — redecode never recovers wasted pixels.
A lighter site is a private one
Compressing locally means your unpublished artwork and staging screenshots never leak to a third-party upload server. Compress in your browser, then deploy what you approve.

Frequently Asked Questions
What is the best image format for websites?
WebP for photos and graphics (with JPG/PNG fallbacks), SVG for logos and icons. All three work fine when you need tiny files for email and feeds.
What quality setting is safe for web photos?
75-85% for large photos, 85-90% for product and text-heavy images. Preview at 100% zoom and stop lowering quality once artifacts appear.
Should I resize before compressing?
Always. Display-size images at 75% quality look identical to 4000px images and load in a fraction of the time.
