Flow
- Normalize raw Base64 or data URL input payload.
- Decode bytes and detect MIME signature.
- Render local preview when decoded MIME is an image type.
Example
Worked example: decode PNG payload
- 1 Paste PNG Base64 sample string.
- 2 Run decode to detect image/png MIME type.
- 3 Tool renders a local image preview card.
Decoded image is previewed with size metadata.
How
- Paste Base64 image text or full data URL.
- Run decode and review MIME type plus decoded size.
- Inspect rendered preview and copy data URL if needed.
Cases
- Debug API responses that return image payloads as Base64.
- Verify copied data URLs before embedding in HTML.
- Confirm whether a Base64 string is really an image.
Avoid
- Pasting non-image Base64 and expecting preview rendering.
- Truncating payload during copy, causing invalid padding.
- Assuming decode verifies image quality or integrity beyond format.
FAQ
Can I paste full data URLs?
Yes, both raw Base64 and data:image/...;base64 inputs are supported.
What if Base64 decodes to non-image data?
The tool shows a safe error explaining that the payload MIME is not image-compatible.
Does base64 to image send my input to a server?
No. Base64 to Image handles the input in your browser whenever possible, so routine conversions, previews, and copy actions stay on your device instead of being sent to Calctrove servers.
