Frequently asked questions

How much can I compress an image?

Most photos compress by 50–80% by converting to WebP or JPEG at 70% quality. The savings depend on the image content.

Does compression resize my image?

Only if you choose a lower scale. Set 100% to keep the same dimensions while only changing quality and format.

Is the original file modified?

Never. The tool creates a new compressed file and your original image stays exactly as it was.
