Frequently Asked Questions
Are my photos uploaded to a server?
Not at all! Everything is processed locally on your device using JavaScript. Your privacy is 100% safe(｀･ω･´)ゞ
Is there a limit on how many images I can process?
Since it runs on your device, the only limit is your browser's memory! But we recommend batching 50-100 at a time.
