Tips for Best Compression Results
Maximize file size reduction while maintaining quality
Start with High-Quality Originals
Always compress from the highest quality source available. Compressing already-compressed images will result in poor quality. Keep originals and work from those.
Use Lossy for Web, Lossless for Print
For website images and social media, lossy compression at 80-90% quality is ideal. For professional printing or archival, use lossless compression to preserve every detail.
Resize Before Compressing
For maximum file size reduction, resize images to their display dimensions first using our Image Resizer, then compress. A 4000px image displayed at 800px wastes bandwidth.
Test Different Quality Levels
Use our preview feature to compare quality levels. Often quality 85 looks identical to 100 but is 50% smaller. Find the sweet spot for your specific image.
Convert to Modern Formats
Consider converting to WebP format using our Image Converter before compressing. WebP typically achieves 25-35% better compression than JPG/PNG at equivalent quality.
