Frequently Asked Questions
Are my images uploaded to a server?
No. All compression happens in your browser using the Canvas API. Your images never leave your device.
What quality should I choose?
80% is a good balance between quality and file size. For web use, 70-80% is ideal. For print, use 90%+.
Does it support PNG with transparency?
Yes, PNG images with transparency are preserved during compression.
