How to Decode a Base64 String Back Into an Image
Published September 10, 2026 · 2 min read
If you've got a base64-encoded image string — pulled from an API response, a config file, or a piece of code — and need to actually see or save it as a real image file, this reverses the encoding and gives you back a normal image.
Try Base64 to ImageSteps
- 1
Open the Base64 to Image tool
Go to the base64 decoder.
- 2
Paste your base64 string
Paste either a full data: URL, or a raw base64 string with the format specified separately.
- 3
Decode
The tool converts the text back into image bytes and displays it.
- 4
View or save the image
The decoded image is shown directly in the page, ready to save.
Frequently asked questions
No — the tool detects a data: URL prefix automatically, or you can specify the assumed image format if you're pasting raw base64 text without one.
You'll get a clear error message rather than a broken image, so you know immediately if the base64 text was corrupted or incomplete.
Yes — the two are companion tools for encoding an image to text and decoding it back again.
Because decoding happens locally, pasting in a base64 string never means sending that data anywhere else to see what it actually shows.
