Frequently Asked Questions
How many images can I convert at once?
Practical limit is bandwidth and browser memory - most laptops handle 100-500 images per batch comfortably. Very large batches (1000+) may slow the browser; split into chunks if needed.
Will the original images stay on my device?
Yes - everything runs locally in your browser. No upload to any server. Originals stay where they are; the WebP outputs are generated locally and offered as a download ZIP.
