Frequently Asked Questions
Are my files uploaded to a server?
Not at all! Everything is processed locally on your device using JavaScript. Your privacy is 100% safe (｀･ω･´)
Is there a limit on how many files I can process?
Since it runs on your device, the only limit is your browser's memory. You can easily batch rename hundreds or thousands of files at once.
Can it extract dates from my iPhone photos?
Yes! It can read EXIF metadata from supported images and automatically use the original capture date in the new filename.
