Frequently Asked Questions

- Output is limited only by your device's memory. Standard photos up to 8000×8000 pixels work well in most browsers.
- Is this tool free to use?
- Yes, completely free. No account, no subscription, no hidden limits.
- Are my files safe? Do you upload them?
- Your files never leave your device. All processing runs locally in your browser using JavaScript — nothing is sent to any server.

- Yes, it works on all modern browsers including mobile Safari and Chrome on iOS and Android.
