Compress screenshots online free. Reduce PNG/JPEG screenshot size while keeping text sharp. Perfect for sharing and documentation.
Screenshots can be surprisingly large, especially PNGs from high-resolution displays. Our Screenshot Compressor reduces file size while keeping text sharp and UI elements clear – perfect for sharing in Slack, email, or documentation.
We use specialized algorithms for screenshot compression:
| Screenshot Type | Recommended Format | Quality/Setting | Expected Size |
|---|---|---|---|
| Full screen (1080p) | JPEG (80%) | 80% quality | 200-400 KB |
| UI element (PNG) | PNG (lossless) | 256 colors | 50-150 KB |
| High DPI (4K) | JPEG (75% + resize to 50%) | 75% quality, 1920px | 300-600 KB |
Original: 5 MB PNG screenshot (4K, full screen)
After PNG quantization (256 colors, lossless): 800 KB (84% saving)
After JPEG (80% quality, 1080p): 250 KB (95% saving)
Quality: Text remains sharp in both cases
