Frequently Asked Questions
How does image compression work?
Our tool uses browser Canvas API to re-encode your image at a lower quality setting. For JPG and WebP, this reduces file size by removing less visible image data. PNG compression uses optimized color indexing.
Is my image data safe?
Yes! All processing happens entirely in your browser. Your images never leave your device â no files are uploaded to any server.
How much can I reduce image file size?
Typical results: JPG at 80% quality reduces size by 40-60%, at 60% quality by 60-80%. WebP often achieves 50-70% reduction at comparable visual quality.
