Frequently asked questions

What is the difference between quality mode and size mode?

Quality mode compresses to the quality level you set — the tool opens at Quality 80%. Size mode instead aims at a target file size, although an exact target size is not always attainable.

Which image formats can I compress?

JPG, PNG and WebP. You can select one or more images, confirm the preview, process them, and download the smaller results.

Will compression soften the detail in my photos?

It can: lossy quality settings can soften detail. Compare the compressed result side by side with your original before keeping the smaller copy.

Are my images uploaded to a server?

No. Everything runs in your browser — nothing is uploaded — so your images stay on your device while they are compressed.
