Questions people ask
What quality setting should I use?
Lower quality means a smaller file but more visible artifacts. Quality 80 is a good balance for photos; use higher values when detail matters.
What format does the compressed image use?
The tool outputs JPEG (or PNG if the original has transparency and you keep PNG). JPEG is much smaller for photos.
Are my images uploaded anywhere?
No. The file is read and processed entirely in your browser. Nothing is uploaded or stored.
