How to Compress Images Without Losing Quality
🖼️Heavy images are the number one cause of slow web pages. Compressing them is the single easiest win for faster load times, better SEO and lower bandwidth bills — and you don't need Photoshop to do it.
Lossless vs lossy compression
Lossless compression removes redundant data with zero visible change. Lossy compression throws away detail your eye barely notices to achieve much smaller files. For photos, a smart lossy setting (around 75–85% quality) usually cuts size by 60–80% with no obvious difference.
Compress an image in 3 steps
- Open the Image Compressor.
- Upload your JPG, PNG or WebP.
- Adjust the quality slider and download the optimized file.
Switch to modern formats
Converting to WebP typically saves another 25–35% over JPG at the same quality. Most browsers support it today, making it the best default for web images.
Bonus: resize before you compress
If you're uploading a 6000px photo to display at 1200px, you're wasting most of those pixels. Use the Image Resizer first, then compress — the combined savings are huge.
