BASE64 to IMAGE Converter
Updated 2026-09-13 · DocsAll Guides
Quick answer: Decode Base64 strings (or full data URIs) back into image files — locally. Open BASE64 转 IMAGE — everything runs locally in your browser, and files never leave your device.
Steps
- Paste the Base64 string or complete data URI into the tool.
- Preview the decoded image.
- Download the file.
Important notes
- Both bare encodings and data:image/png;base64,... URIs are accepted; if a bare string decodes wrong, try adding the correct prefix.
- Local decoding — verification codes and ID images never leave the device.
Common questions
Decode fails — why? Stray whitespace/newlines, or you are actually looking at URL-encoded data.
Reverse direction? Use Image to Base64.
When to use this
When previewing fails, the encoding is usually truncated at copy time — compare the tail of the string with the source before troubleshooting further.
