Frequently Asked Questions

How do I convert Base64 to an image?
Paste your Base64 string (with or without the data:image prefix) and click "Decode Image". The tool shows a preview with image details, and you can download the image directly.
What image formats are supported?
PNG, JPEG, GIF, WebP, SVG, BMP, and ICO are all supported. The format is auto-detected from the data URI prefix, or you can select it manually from the dropdown.
Do I need the data URI prefix?
No! You can paste the full data URI (data:image/png;base64,...) or just the raw Base64 characters. If you paste raw Base64, select the format from the dropdown or leave it on auto-detect (defaults to PNG).
Is there a file size limit?
Everything runs in your browser, so there's no server limit. Very large Base64 strings (10MB+) may be slow, but typical images work instantly.
Is my data safe?
Yes! All conversion happens entirely in your browser using JavaScript. No data is uploaded to any server. Your Base64 strings and images never leave your device.
