Frequently Asked Questions
Yes — completely free with no limits or watermarks. Convertlo runs entirely in your browser, so there are no server costs to pass on.

No. All conversion happens locally in your browser using the HTML5 Canvas API. Your files never leave your device.
PNG uses lossless compression, which results in larger file sizes than JPEG for photographic images. This is normal and expected — the trade-off is zero quality loss.
