Frequently asked questions

How does the image compressor work?

It uses HTML5 Canvas APIs in the browser to resize images and adjust compression quality settings (lossy format encoding). All processing occurs entirely locally inside your browser.

Are my images uploaded to a server?

No. Your images never leave your computer. Everything is processed locally in memory via client-side JavaScript, ensuring 100% privacy.

Which formats are supported for compression?

You can upload JPG, JPEG, PNG, and WebP formats. Compression settings (quality adjustment) are highly effective for lossy formats like JPG and WebP. For PNGs, you can resize dimensions or convert them to WebP/JPG for smaller sizes.
