Base64 image strings turn up everywhere in development — inside HTML, CSS, JSON exports, API responses and configuration files. When you have one of these long strings and need the actual picture file back, the Base64 to Image tool decodes it, shows you a preview, and lets you download the real image.
How to use the Base64 to Image tool
- Paste your Base64 string, with or without the
data:prefix. - Click Decode.
- Check the preview to confirm it is the right image.
- Download it as a file.
Turning code back into a file
This is the natural companion to encoding. Maybe you found an inlined icon in someone's stylesheet and want to reuse it as a normal image, or an export tool handed you a data URI instead of a file. Rather than puzzling over the string, you paste it here and immediately get a usable picture. The tool reads the type from the data URI when present, so it knows whether to give you a PNG, JPG or other format.
Tips for clean decoding
- Include the full
data:prefix when you have it, so the format is detected correctly. - Strip any surrounding quotes or code so only the Base64 itself is pasted.
- If decoding fails, the string is probably incomplete or not actually image data.
- Rename the download to suit your project once you have it.
Decoding happens entirely in your browser, so whatever the string contains never leaves your device. It is a private, instant way to recover an image from raw text.
