FAQ
Yes, completely safe. All processing happens locally in your browser. Your images are never sent to any server and are not stored anywhere — everything stays on your device.
The tool supports all common image formats including PNG, JPEG, GIF, WebP, SVG, BMP, and more.
A Base64 string contains only the raw encoded data. A Data URI includes a prefix like 'data:image/png;base64,' and can be used directly as the value of an src attribute in HTML or CSS.
There is no strict limit, but very large files may slow down your browser since Base64 encoding increases the data size by approximately 33%.
Embedding images directly into HTML, CSS, or JSON files, sending images through APIs without file uploads, reducing HTTP requests in web apps, and storing images in databases as text.
