FreeDecode Base64 string back to image file
About Base64 to Image
A Base64 string is just an image encoded as plain text — useful for embedding pictures directly in code or data, but useless to actually look at until it's decoded. This tool converts Base64 back to an image file instantly: paste the string in, and get back a viewable, downloadable image.
It's handy for developers debugging embedded images, checking what a data URI actually contains, or recovering an image file from a Base64 string pulled out of code, an API response or a database field. Free, no signup, works entirely in the browser.
Common uses
- Checking what image a Base64 data URI in your code actually contains
- Recovering an image file from a Base64 string stored in a database or API response
- Debugging an embedded image that isn't rendering correctly
- Converting a Base64-encoded image back to a normal file for reuse elsewhere

FAQ
What image formats can this decode?
Standard Base64-encoded image data — JPG, PNG, GIF and similar formats embedded as a data URI or raw Base64 string.
Do I need the full data URI, or just the Base64 part?
Either works — paste the full data:image/... string or just the raw Base64 characters.
Is the image uploaded anywhere?
No, the decoding happens in your browser session, so nothing is uploaded or stored on a server.
Can I convert an image back to Base64 too?
This tool handles Base64-to-image; for the reverse direction, use an image-to-Base64 encoder tool.
How do I decode a Base64 image?
Paste your Base64 string (with or without the data:image/...;base64, prefix) and click Convert. The image will be decoded and ready to download.
What if my Base64 string has the data URL prefix?
No problem — ToolHub automatically strips the data:image/...;base64, prefix and decodes the raw Base64 data.
What formats can I download the decoded image as?
The output format depends on the original encoded image. You can download it in its original format.
Can I use Base64 to Image on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
