Frequently asked questions
Is this tool free?+
Yes, completely free with no signup required.
Are my images uploaded to a server?+
No. Conversion happens locally in your browser using the FileReader API — nothing is uploaded.
What's the maximum file size?+
Since conversion happens in-browser, the practical limit is your device's memory rather than a server rule. Very large images (50MB+) may be slow to encode.
