Can I compress images to a specific KB size?

Choose Target file size and enter a limit. JPG and WebP adjust quality; PNG preserves transparency. Allow smaller dimensions if needed. Files that cannot meet the limit are not downloaded.

Are my images uploaded?

No. Images are compressed in your browser and never leave your device.

PNG and WebP keep transparency. JPG can’t store it, so transparent areas become white.
