What formats are supported?

The tool auto-detects PNG, JPEG, WebP, and GIF from the Base64 data. If you paste a raw Base64 string (without the data: prefix), the tool inspects the magic bytes to determine the image format automatically.

What is the difference between a data URI and raw Base64?

A data URI starts with data:image/png;base64, followed by the encoded data. Raw Base64 is just the encoded characters without the prefix. This tool accepts both formats — it will add the correct prefix if missing.

Is there a size limit?

There is no hard limit, but very large Base64 strings (over 10 MB of encoded data) may cause the browser to slow down. For best results, keep the input under a few megabytes.
