Frequently asked questions

Are my images uploaded to a server?

No. Compression runs in your browser, so the images stay on your device.

Which format compresses best?

WebP is usually the smallest at a similar look. JPG works everywhere. PNG stays lossless, so it shrinks less.

What does target size do?

You enter a size in KB and the tool finds the highest quality that fits. PNG files are converted to WebP to reach it.

Will compression change how my image looks?

Lower quality saves more space and may add slight blur. Try 75% first and compare.
