Built for image Data URLs
A Data URL combines the detected MIME type and Base64 payload in one portable value.
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
What does a Data URL look like?
It starts with data:image/png;base64, (or another MIME type) followed by the Base64 payload in one string you can paste anywhere.
Where are Data URLs commonly used?
Inline images in HTML emails, CSS backgrounds, canvas exports, JSON APIs, and small self-contained web prototypes.
When should I use Base64 for image Data URLs?
Use it when a text-only channel or API must carry binary data, or when a small image Data URLs asset needs to live inside a self-contained document. Prefer separate files for large, cacheable public assets.
