Convert Base64 to an Image

Turning Base64 back into a file

Base64 strings show up everywhere — in CSS, in API responses, in saved data URIs, in config files. When you have one and need the actual image, this decoder converts it back: paste the string (with or without the data: prefix), and it rebuilds the original file so you can preview and save it.

The decoder is forgiving. It strips a data: URI prefix, removes line breaks and stray whitespace, handles URL-safe Base64, and repairs missing padding automatically. It then checks the decoded bytes really are an image, so a wrong or corrupt paste fails with a clear message instead of saving a broken file.

How to convert Base64 to an image

1. Paste your Base64. Drop the raw Base64 body or a full data:image/…;base64,… URI into the box on the Decode tab.
2. Decode. Click Decode — the image appears instantly in a preview, with its detected type and size.
3. Download. Save the decoded image to your device; the file gets the correct extension automatically.

With or without the prefix

You can paste a full data:image/png;base64,… URI or just the part after the comma — the tool handles both. It even detects the real format from the bytes, so the download is correct even if the prefix was missing or wrong.
