Questions fréquentes
Are my images uploaded to a server?
No. Everything runs locally in your browser — your images never leave your device and nothing is stored.
Should I inline large images?
No. Base64 makes data about 33% larger, so it's best for small images and icons. The tool warns on large files.
What is a data URL?
A string that begins with data:image/...;base64, and contains the whole image, so it can be used directly as an image source.
Is it really free?
Yes — free, with no signup, no watermark and no limits.
