Base64 to Image Converter
Paste a base64 string and instantly preview the image — PNG, JPEG, WebP, GIF, SVG. Everything runs in your browser. Nothing leaves your device.
Paste your key once — it's saved in your browser and injected into code snippets automatically.
How it works
Paste base64
Raw base64 or a full data URL (both are supported). Accepted formats: PNG, JPEG, GIF, WebP, SVG.
Instant preview
The image renders immediately in your browser using the native atob() API — no server involved.
Download or copy
Download the decoded image file, or copy the base64 back to clipboard for use in code.
Frequently asked questions
Is my data safe?
Yes. The entire conversion happens in your browser using the Web Crypto / Canvas APIs. No data is transmitted to any server.
What image formats are supported?
PNG, JPEG, WebP, GIF, and SVG. The tool auto-detects the format from the binary header of the base64 string.
What is a base64 image?
Base64 is an encoding scheme that converts binary data (like an image file) into ASCII text. APIs — including AI image generation endpoints — often return images as base64 strings so they can be embedded in JSON responses.
Can I convert an image to base64?
Yes — click "Encode image" to upload a local file. The tool reads it with FileReader and shows you the base64 string you can copy and use in your code.
Building with AI image generation?
AICredits gives you one API key to access Flux, DALL-E, Gemini Imagen, and 300+ other models — pay only for what you use in INR.
