From data URI back to a file
If you have an image encoded as Base64 — from a data URI in some CSS, an API response, or a config file — this turns it back into a viewable, downloadable image. Both raw Base64 and full data URIs are accepted.
Frequently asked questions
Is my data uploaded to a server?
No. Decoding and preview happen entirely in your browser; nothing is sent anywhere.
Do I need the data: prefix?
No. You can paste a full data URI or just the raw Base64 — raw Base64 is assumed to be a PNG.
Why does my image not show?
The Base64 may be incomplete or not an image. Make sure you copied the whole string.
