Why Compress Images?
Large images are the number one cause of slow websites. Every unnecessary kilobyte delays page rendering, hurts your Core Web Vitals score, and frustrates mobile visitors on slow connections. Compressing your images before uploading them to a website, blog, online store, or social media profile is the single easiest performance win available.
Benefits of compressing images with JPG Small:
- Faster page loads — smaller images render almost instantly, improving user experience.
- Better SEO — Google uses page speed as a ranking signal, so lighter pages rank higher.
- Lower bandwidth costs — especially important for high-traffic blogs and stores.
- More storage space — keep more photos on your device or cloud drive.
- Easier sharing — fit under email attachment limits or messaging app size caps.
Which Format Should You Choose?
- WebP — the best all-round choice for the web. Typically 25–35% smaller than JPG at the same visual quality, and supports transparency.
- JPEG — the universal choice for photographs. Supported by every browser, device, and app.
- PNG — use only when you need lossless quality or transparency and can accept larger files.
Recommended Quality Settings
- 90–100% — maximum quality, minimal compression. Use for print or archival.
- 75–85% — the sweet spot for websites. Almost no visible difference at normal viewing size.
- 60–75% — good balance for thumbnails, previews, and social media.
- Below 60% — visible artifacts. Only use for tiny previews or icons.
