Frequently Asked Questions

What image formats are supported?
PNG, JPG/JPEG, GIF, WebP, SVG, and BMP. These are the formats most commonly encoded as Base64 for web use.
What is a Data URL?
A Data URL is a Base64 string prefixed with 'data:image/[format];base64,'. It can be used directly in HTML/CSS as an image source without uploading a file.
How do I use Base64 images in HTML?
Use the Data URL as the src attribute: <img src="data:image/png;base64,iVBORw0KGgo...">. The browser decodes it directly without a server request.
What is the reverse decode feature?
Paste any Base64 or Data URL string and the tool will decode it back to an image file and offer a download button.
Is my image sent to a server?
No. All encoding and decoding is done locally in the browser using Canvas API. Your images never leave your device.
