No registration, watermark, queue, or server upload is required.
Use Base64 wisely
Base64 is ideal for text-only APIs, small embedded assets, test fixtures, and portable documents. It increases payload size, so external files are usually better for large public assets.
Frequently asked questions
Can I paste a full Data URL instead of raw Base64?
Yes. Paste either plain Base64 or a complete data:image/...;base64,... value. The tool extracts the payload and detects the image format automatically.
Which image formats are detected?
PNG, JPEG, GIF, WebP, and SVG are recognized from their binary signatures when no MIME type is included in the input.
When should I use Base64 for Base64 images?
Use it when a text-only channel or API must carry binary data, or when a small Base64 images asset needs to live inside a self-contained document. Prefer separate files for large, cacheable public assets.
