Your files never leave your device. All processing happens in your browser.
Paste your Base64 string or data URI into the box in Img Stop's Base64 to Image tool and press Decode to image. The tool detects the image type, shows a preview and gives you a file to download. Decoding happens in your browser, so your data is not sent anywhere.
About the Base64 to Image
Base64 to Image turns encoded text back into a real picture file. You can paste a full data URI such as data:image/png;base64, followed by the code, or only the Base64 characters. Img Stop removes spaces and line breaks, decodes the text and checks the first bytes of the file to find out whether it is JPG, PNG, GIF, WebP, BMP, SVG or AVIF.
Base64 images often appear in API responses, HTML source code, CSS files, JSON exports and email data. Reading the code by eye is impossible, so a decoder lets you see what the image is and save it as a normal file. This is useful for developers who debug apps and for anyone who needs to recover a picture that is stored as text.

Tips for the best result
- Copy the whole string. If even a few characters are missing at the end, the image may not decode or may look broken.
- If the tool says the text is not an image, the Base64 may hold a PDF or another file type.
- Keep the data:image prefix if you have it. The tool then uses the exact type written there.
Frequently asked questions
How do I convert Base64 to an image?
Copy the Base64 text, paste it into the box on Img Stop's Base64 to Image tool and press Decode to image. The picture appears in the preview with its width and height. Then download it. The file keeps its original format, such as PNG or JPG.
Do I need the data:image prefix?
No. You can paste the full data URI or just the Base64 characters. Without the prefix, the tool reads the first bytes of the decoded data to work out the file type. With the prefix, it uses the type written there.
Why does it say this is not valid Base64?
The text contains characters that Base64 does not use, or part of it is missing. Make sure you copied the full string without quotes, commas or extra code around it. Spaces and line breaks are fine, because the tool removes them before decoding.
What format will the downloaded image be?
The decoded file is saved in its original format, so a PNG stays PNG and a JPG stays JPG. Supported types include JPG, PNG, GIF, WebP, BMP, SVG and AVIF. If you need another format, convert the saved file with the Image Converter.
Is it safe to decode private Base64 data here?
Yes. The text is decoded by JavaScript in your own browser. Nothing is sent to a server or saved by Img Stop, so private screenshots, scans and other images inside your Base64 data stay on your device.
