Frequently Asked Questions
How does the image compressor work?
Our compressor uses the HTML5 Canvas API to re-encode your image at a specified quality level. For JPG and WebP, you can adjust the quality slider. For PNG, compression is lossless.
Are my images uploaded to a server?
No. All image processing happens in your browser. Your images never leave your device, ensuring complete privacy.
What format should I use for compression?
WebP offers the best compression ratio. JPG is best for photographs. PNG is lossless and best for images with transparency or text.
