Frequently Asked Questions
What image formats are supported?
JPG, PNG, WebP, GIF and BMP are all supported. For web use, consider converting to WebP for the best size-to-quality ratio.
Will quality be affected?
At 75-85% quality, compression is virtually imperceptible to the human eye. Lower settings produce smaller files with slight quality reduction visible only at very large sizes.
Is my image uploaded to a server?
No. The Image Compressor runs entirely in your browser. Your image never leaves your device.
What is the best quality setting for web images?
For web use, 75-80% quality typically produces excellent results at significantly smaller file sizes. For print, use 90%+ to preserve fine detail.
