Ways to Reduce Image Size
There are several techniques to reduce image file size:
- Compression - Reduce quality to decrease file size (most effective)
- Resizing - Reduce pixel dimensions to match actual display size
- Format conversion - Convert to more efficient formats like WebP
- Metadata removal - Strip EXIF data, GPS coordinates, and other metadata
Recommended Settings by Use Case
| Use Case | Quality | Max Width | Format |
|---|---|---|---|
| Email attachment | 70% | 1200px | JPEG |
| Website hero image | 80% | 1920px | WebP |
| Social media | 75% | 1080px | JPEG/WebP |
| Thumbnails | 60% | 400px | JPEG/WebP |
| Document upload | 70% | 1500px | JPEG |
How Much Can Files Be Reduced?
Typical reduction rates depend on the original image and chosen settings:
- Photos (JPEG) - 50-70% reduction at 70-80% quality
- Graphics (PNG) - 30-60% reduction with optimization
- Any image to WebP - 25-35% smaller than JPEG
- With resizing - Up to 90% reduction possible
Tips for Optimal Reduction
- Use our presets - They're optimized for common use cases
- Consider WebP - It offers the best compression ratios
- Resize to actual display size - Don't use 4000px images for 800px displays
- Test different quality levels - Find the lowest acceptable quality
- Strip metadata - This alone can save significant space
