Frequently Asked Questions
Is the image compressor free?
Yes! Compress unlimited images for free. No signup, no watermarks, no file limits.
Are my images uploaded to a server?
No. All compression happens in your browser using the Canvas API. Your images never leave your device.
How much can I reduce file size?
At 60% quality, most photos lose 50-70% of file size with barely visible quality loss. JPG and WebP compress much more than PNG.
Should I compress JPG or convert to WebP?
WebP typically produces 25-35% smaller files than JPG at the same quality level. If browser compatibility matters, keep JPG. For web performance, use WebP.
Does compressing reduce image dimensions?
No. Compression only reduces file size by encoding data more efficiently. The width and height remain exactly the same.
