✨ Lossless Compression
Preserves all image data. Original quality is maintained but files stay larger.
Best for: Graphics, logos, screenshots
Formats: PNG, WebP (lossless)
Savings: 10-30% reduction
Best Image Format for Each Use Case
| Use Case | Best Format | Why |
|---|---|---|
| Photos & complex images | JPEG | Best compression for realistic images |
| Logos & graphics | PNG | Supports transparency, sharp edges |
| Modern web (all types) | WebP | 30% smaller than JPEG/PNG |
| Screenshots | PNG | Preserves text clarity |
Step-by-Step: Compress Images Like a Pro
Choose Your Quality Level
For most web images, 70-80% quality is the sweet spot. You won't see any difference, but file sizes drop dramatically.
Resize Before Compressing
Don't upload a 4000px image if it's displayed at 800px. Resize to the actual display size first for huge savings.
Use a Client-Side Tool
Browser-based compressors process images on your device — faster, more private, and no upload limits.
Compare Before & After
Always check the compressed result. If quality looks bad, increase the quality slider slightly.
