Base64 to Image Converter
Got a wall of Base64 from an API, a log or an old email? Paste it here (with or without the data: prefix) and the tool decodes it, detects the real format from the magic bytes — JPG, PNG, GIF or WebP — previews it, and lets you download the file. Malformed strings get a specific error instead of a broken picture.
How to base64 to Image
- Paste the data URL or raw Base64.
- Click decode.
- Check the preview and detected format, then download.
Frequently asked questions
It says the decoded bytes are not an image — why?
The string decoded fine, but the content is something else (text, audio, a zip…). The tool checks the file signature rather than trusting any prefix, and tells you instead of offering a corrupt download.
My string has line breaks — is that OK?
Yes, whitespace is ignored for raw Base64. The data: prefix form is also accepted as-is.
