Frequently Asked Questions
How does image compression work?
Our tool uses your browser's built-in Canvas API to re-encode images at a lower quality level. This reduces file size by removing unnecessary data while keeping the visual quality acceptable.
Will my images lose quality?
Some quality loss is inevitable with lossy compression (JPG, WebP). However, at 80% quality, the difference is barely noticeable to the human eye while achieving significant file size reduction.
What quality level should I use?
80% is a good default that balances quality and file size. For web images, 70-80% is usually sufficient. For photos you want to keep, use 85-95%.
Are my images uploaded to a server?
No. All processing happens entirely in your browser. Your images never leave your device. We have zero access to your files.
Can I compress PNG images?
Yes. PNG compression works differently — it's lossless, so the file size reduction may be less dramatic. For better PNG compression, consider converting to WebP format.
How much can I reduce file size?
It depends on the original image. JPG images can typically be reduced by 40-70% at 80% quality. WebP often achieves even better compression ratios.
