About JPEG Compression
How it works, and why it matters for your images
Lossy vs Lossless
JPEG is a lossy format — some image data is discarded to reduce file size. The trick is controlling how much is lost. Our tool adjusts quality in small steps to find the smallest file that still looks good to the eye.
- Reduces file size by 50–90%
- Preserves visual quality at quality ≥ 70
- Speeds up page loading
Why Compress?
Large images slow down pages, hurt Core Web Vitals scores, and use unnecessary storage. Compressing before uploading to a website, email, or social media makes a real difference.
Common reasons to compress:
- • Faster page loads, better SEO
- • Smaller email attachments
- • Optimizing images for mobile
- • Reducing storage and bandwidth costs
