Base64 → Image

About Base64 to Image

A Base64 data URL is just a long string of letters and digits that, when interpreted properly, decodes back into the original image. Convertora's Base64-to-image tool takes that string — whether it's a full data URL or just the raw Base64 payload — verifies it, decodes it back to a picture, and lets you preview and download the file. Like every Convertora tool, the decoding happens entirely inside your browser, so the data never travels to a server.

This is the practical inverse of encoding an image. You'd reach for it when an API returns an image as a Base64 string, when you've copied a data URL out of a stylesheet or HTML page and want the original file back, when debugging a payload that won't render, or when extracting an image from a JSON export that embedded it inline. The tool handles common variations: plain Base64, data URLs with explicit MIME types, line breaks, and surrounding whitespace.

How to use it

1. 1Paste the Base64 string into the text area. It can be a full data URL (data:image/png;base64,…) or just the encoded payload — the tool detects both.
2. 2Click Decode. For a raw payload, Convertora decodes the bytes and identifies the real format from the file's magic numbers — PNG, JPEG, GIF, WebP, BMP, AVIF, and SVG are recognized — rather than guessing from a header.
3. 3Preview the decoded picture to confirm it looks right. If the string is invalid or isn't an image, you get a clear error instead of a broken preview.
4. 4Click Download to save it to your device. The file extension is chosen from the actual detected format, so the saved file opens correctly.

What you get

• Accepts complete data URLs (data:image/png;base64,…) or bare Base64 payloads, with line breaks and stray whitespace stripped automatically.
• Detects the real image format (PNG, JPG, GIF, WebP, BMP, AVIF, SVG) from the decoded bytes when you paste a raw payload — no header required.
• Live preview before download so you can verify the decode succeeded.
• Clear error message if the string is invalid or corrupted.

Common use cases

• Extracting an image that an API returned as a Base64 field in a JSON response.
• Recovering an inline image from an HTML or CSS file you've inherited that uses data URLs for graphics.
• Debugging an image-upload flow where you can see the encoded string but the rendering downstream isn't working.
• Pulling a profile picture or avatar out of a webhook payload or database export.
• Saving a screenshot embedded in a Markdown document or chat export as an actual file.

Tips

• If you've extracted the Base64 from JSON, remember to unescape it — escaped slashes and quote characters can be enough to break decoding.
• Animated GIFs decode and download intact (Base64 is lossless), but the preview shows the animation only as your browser plays it — the saved file keeps every frame.
