常见问题
Are my images uploaded to a server?
No. Everything runs locally in your browser — your images never leave your device and nothing is stored.
What input is accepted?
A full data URL (data:image/...;base64,...) or just the raw Base64 — the tool adds a PNG header if needed.
Why does it say invalid?
The text isn't valid Base64 image data. Check that you copied the whole string without extra characters.
Is it really free?
Yes — free, with no signup, no watermark and no limits.
