How to Compress Images Without Losing Quality
Learn how image compression works and how to shrink file sizes while keeping your pictures looking sharp.
Large images slow down websites and eat up storage. The good news is that you can usually reduce an image by 60-80% with almost no visible difference.
Start with the right format
Use JPG for photos and PNG for graphics with transparency. Modern formats like WebP often give the best balance of quality and size.
Compress at the right moment
Compress as the final step, after any resizing or cropping. Compressing an image twice can introduce unnecessary artifacts.
