Are my images uploaded?
No. The conversion runs inside your browser, so your images stay on your device. Files are only uploaded if you choose to optimize them with Arche, and those are deleted within 48 hours.
What is Arche?
Arche makes JPEG, PNG and WebP images smaller without changing their format or pixel size, and strips metadata such as EXIF location. It is free without an account; Pro raises the batch limits.
