How much smaller will my images be?

Typical photos shrink by 40–80% at 70–80% quality, especially when converted to WebP. Each result shows the exact before/after size.

Why did my PNG get larger?

PNG is lossless, so re-encoding a well-optimised PNG can produce a bigger file. Choose WebP or JPG output, or keep the original.

Tips

Use WebP for the best size/quality ratio on the web.
Set a max dimension (e.g. 2048 px) for big phone photos.
Keep quality between 70 and 85% for photos.
