Base64 to image — frequently asked questions
How do I convert Base64 to an image?
Paste your Base64 string or data URI in the box above. The image is shown instantly — click Download image to save it.
Do I need the data:image/png;base64 prefix?
No. Paste just the Base64 text and the tool works out whether it is a PNG, JPG, GIF, WebP, BMP, ICO, SVG or AVIF from its first bytes.
Why does it say my Base64 is invalid?
Base64 only uses letters, numbers, +, / and = (or - and _ in URL-safe Base64). Check that the text was copied completely and nothing else was pasted with it.
Can I decode Base64 from an API or JSON response?
Yes. Copy the Base64 value (with or without its quotes) and paste it here to see and save the image.
Is my data sent anywhere?
No. Decoding happens in your browser, so the Base64 text and the image never leave your device.
