How does the image compressor work?

The compressor uses your browser's Canvas API to re-encode the image at a lower quality setting. JPEG and WebP use lossy compression that discards imperceptible detail to reduce file size. PNG uses lossless compression so quality is always fully preserved.

What image formats are supported?

You can upload JPEG, PNG, WebP, or GIF images. The compressed output can be saved as JPEG or WebP — both support quality-based compression for maximum size reduction.

How much can I reduce the file size?

At 70–80% quality, JPEG and WebP images are typically 50–70% smaller with no visible difference. At 50% quality, savings can exceed 80–90%.

Is my image uploaded to a server?

No. All compression happens locally in your browser using the Canvas API. Your image never leaves your device.

Why is WebP better than JPEG for compression?

WebP typically achieves 25–35% better compression than JPEG at the same visual quality level, and it supports transparency like PNG. WebP is supported in all modern browsers.
