Lossy vs. Lossless Compression
This tool primarily uses lossy compression, which selectively discards data that the human eye is less sensitive to. This allows for massive file size reductions.
By adjusting the quality slider, you control how much data is discarded. Higher quality settings retain more detail but result in larger files.
Common Questions
How much space can I save?
It varies by image, but saving 50-80% of file size is common without noticeable quality loss. You can adjust the compression level to balance size vs. quality.
Does it reduce quality?
Compression always involves some trade-off, but our 'smart' compression defaults aim to preserve visual quality so the difference is invisible to the naked eye.
Is my data secure?
Absolutely. Your images are compressed locally in your web browser. They never leave your device and are not uploaded to any server.
What formats are supported?
We support compressing JPG, PNG, and WebP images. You can also convert images to modern formats like WebP for even better compression.
