Frequently Asked Questions
Does compress jpg without losing quality reduce image quality?
At high quality settings, the difference is virtually invisible to the human eye. The tool uses smart optimization to remove metadata and redundant data before applying minimal lossy compression.
Is my image uploaded to a server?
No. All compression is done using the HTML Canvas API directly in your browser. Your images never leave your device and are never sent to any server.
What is the best format for compressed images?
WebP is 25-35% smaller than JPEG at the same quality and supports transparency. For photos, JPEG/WebP is ideal. For graphics with transparency, WebP or PNG is best.
