Frequently Asked Questions
Are my images uploaded to a server?
No. Every conversion runs locally in your browser using your device's own processor. Your images never leave your computer or phone, and nothing is stored on our servers.
Is it free, and are there limits?
It's completely free with no account required. Because processing happens on your device, there's no per-file upload limit — the practical ceiling is your device's available memory. You can batch many files and download them as a single ZIP.
Can I convert several images at once?
Yes. Drop or select multiple files and they'll be processed in a controlled queue so your browser stays responsive. Each file shows its own progress, and you can download them individually or all together as a ZIP.
