Reduce image file size without visible quality loss. Perfect for meeting upload limits on social media platforms. Free, private, browser-based.
Image compression reduces file size by removing redundant data. Lossy compression (JPG, WebP) discards information the human eye is unlikely to notice. Lossless compression (PNG) reorganizes data without any quality loss but achieves smaller reductions.
| Platform | Max File Size | Recommended Format |
|---|---|---|
| YouTube Thumbnail | 2 MB | JPG 85% |
| 30 MB | JPG 90% | |
| X / Twitter | 5 MB (JPG) / 15 MB (PNG/GIF) | JPG 85% |
| 30 MB | JPG 85% | |
| 10 MB | JPG 85% |
Lossy compression (JPG, WebP) does reduce quality, but at 80-85% quality settings the difference is virtually invisible to the human eye. The file size reduction is typically 60-80%.
For photos shared on social media, 80-85% provides an excellent balance. Below 70%, compression artifacts become noticeable. Above 90%, file sizes increase significantly with minimal visual improvement.
