Frequently asked questions

Does the tool send my images to a server?

No. All compression is performed in your browser using the Canvas API. Your images never leave your device.

What quality level should I use?

For web use, 75–85% quality typically provides a good balance of visual quality and file size reduction. Higher is better for print.

Which formats are supported?

JPEG, PNG, and WebP. Note that PNG compression here converts to JPEG under the hood, producing a lossy result. For a true lossless PNG output, use a dedicated tool.

How much can it compress an image?

Results vary by image content, but most photos can be reduced by 50–80% with minimal visible quality loss at 80% quality.
