Free tool
Make your images smaller without them looking worse.
Drop in photos, choose a format and width, and download files that are often 70 to 90% smaller. Your images are never uploaded: the work happens on your device.
Why it matters
- Big photos are the top reason small sites load slowly
- Google uses page speed on phones as a ranking signal
- Smaller files also mean lower hosting bills

Images, briefly
The fastest page is the one with the smallest images.
A single phone photo can be 4 MB; the same picture at website size is often under 200 KB. Resize to the width it is shown at, then compress.
- Which format should I use?
- WebP for websites: it is the smallest and every current browser shows it. JPEG when a file must open anywhere, such as email attachments. PNG only for logos and graphics with sharp edges or transparency.
- What quality setting is best?
- 70 to 80% is usually indistinguishable from the original at normal viewing size. Go lower for thumbnails, higher for photography portfolios.
- What width should I use?
- Rarely more than 1600 px for a full-width image on a website, 800 to 1200 px for images inside text, and 400 px for avatars. Larger than the space it is shown in just wastes download time.
- Are my images uploaded?
- No. They are processed in your browser and never leave your device, so private photos and documents stay private.
- Is your whole site slow?
- The SEO Sprint measures speed on real phones and fixes images, caching and the other things that hold your pages back.
