Getting the balance right
For photos, a quality of 70–85% usually cuts file size by half or more with no visible difference. Screenshots and graphics with sharp edges compress better as PNG or WebP.
Private by design
Online compressors normally upload your image to their server. This one doesn't: your browser does the work.
FAQ
What's the best format for small files?
WebP usually gives the smallest files at the same visual quality, and every modern browser supports it.
Will compressing remove metadata?
Yes. Re-encoding through the browser drops EXIF data, including location.
