View key capabilities & tips
Key capabilities:
- Generates standard data URI strings (`data:image/png;base64,...`) and raw Base64 strings
- Supports JPG, PNG, WebP, GIF, SVG, and AVIF image formats
- Interactive preview with one-click copy to clipboard and text file download
- Pure client-side encoding with zero data transmission to external servers
Tips:
- Base64 encoding increases file payload size by approximately 33%; best used for small icons and thumbnails under 50KB.
- Choose "Data URI" format if you plan to paste directly into `src="..."` or `background: url(...)` attributes.
- Use the copy button to quickly paste the encoded string into your code editor.
