FAQ

Tout ce que vous devez savoir sur le Bulk Image Optimizer.

Are my images uploaded to a server when compressing?

No. The bulk image optimizer runs entirely in your browser using local Web Workers. Unlike our competitors, your images never leave your device — giving you total privacy and zero rate limit throttling.

What image formats does the bulk optimizer support?

The optimizer supports JPG, JPEG, PNG, WebP, and HEIC formats. Our professional optimization engine intelligently rebuilds the image structure resulting in 60-90% smaller files.

Why should I convert to WebP or the optimised format?

Modern image formats compress images significantly better than JPEG or PNG at the same visual quality. Switching can reduce file size by 25–50%, speeding up your website and reducing storage costs. The optimizer automatically picks the best format your browser supports.

How many images can I compress at once?

Free users can process 25 images at once. Pro users unlock massive bulk processing of up to 500 images per batch using multi-threaded web workers to prevent browser freezing.
