FAQ
Are my files uploaded anywhere?
No. The whole process runs inside your browser. Your images never leave your device and nothing is sent to a server.
How do you compress to exactly 300KB?
The tool repeatedly re-encodes the image at different quality levels and keeps the best one that stays at or under 300KB.
Will quality drop?
It picks the highest quality that still fits your target size. Smaller targets mean more compression, so set a realistic size for your image.
