Base64 Image FAQ
Is my image uploaded to a server?
No. The conversion runs locally in your browser, so the image data stays on your device.
Can I paste a full data URL?
Yes. You can paste either a plain Base64 string or a value like data:image/png;base64,...
Why does the tool show an error?
The most common reasons are invalid Base64 text, unsupported image data, or a string that was copied only partially.
Which image formats are supported?
JPG, JPEG, PNG, GIF, BMP, TIFF, SVG, WEBP, AVIF, and ICO are supported.
Should I use Base64 images on production websites?
Small icons can be fine, but large images are usually better served as separate optimized files for better caching and page speed.
