How much smaller will the files be?
It depends on the image. Photos and illustrations often shrink by 60-90 percent; tiny icons or already optimized PNGs may barely change, and the tool shows the real change per file.
Do all browsers support WebP?
All current major browsers display WebP. Very old software may not, so keep a PNG or JPG copy if you must support it.
What quality should I pick?
Start at 85. Text-heavy graphics may need 90 or more to stay crisp; photos often look fine at 75-80.
Is it private?
Yes. The conversion runs locally and the images are never uploaded.
