Base64 to GIF
Paste a Base64 string or a data:image/gif;base64, URI below and click Decode Base64 to GIF. The decoder checks the file signature, shows a preview and lets you download the result as a real .gif file.
How to convert Base64 to GIF online
- Paste the Base64 value into the input box. Data URIs, whitespace and line breaks are handled automatically.
- Press Decode Base64 to GIF.
- Check the preview and the detected file type, dimensions and size.
- Click Download to save the .gif file.
Important notes about the decoder
- The decoder detects the real file type from the decoded bytes (magic number). If your string is not actually GIF, you will see the real type and can still download it.
- Invalid characters are reported instead of silently producing a broken file. If decoding fails, try the Base64 repair tool.
- Nothing is uploaded: the data is decoded locally by your browser, so even confidential documents stay on your device.
About GIF
GIF was introduced by CompuServe in 1987. Each frame is limited to a palette of 256 colors and compressed with LZW, and the format supports simple animation and single-color (on/off) transparency.
The famous 1×1 transparent tracking pixel is a tiny GIF that encodes to only 56 Base64 characters, which is why GIFs are still popular for inline placeholders and email spacers.

Frequently asked questions
How do I convert Base64 to GIF?
Paste the Base64 string into the box above and click "Decode Base64 to GIF". You can preview the result and download it as a .gif file.
Why is my Base64 GIF not displaying?
Usually the string is truncated, contains URL-safe characters, or was double-encoded. The decoder reports the exact problem; the Base64 repair tool can fix most of them automatically.
Do I need to remove the data URI prefix?
No. The decoder strips "data:...;base64," automatically and uses the MIME type from it as a hint.
