Encode images for HTML email templates to ensure they display correctly across different email clients, even when external images are blocked.
Compress images during encoding with quality control (1-100%) and dimension limits to reduce Base64 string size while maintaining quality.
Choose between Base64 string, data URL, or data URI formats depending on your use case and integration requirements.
Support for all major image formats including PNG, JPEG, WebP, GIF, and SVG with automatic format detection and validation.
Preview images before and after conversion with validation feedback to ensure correct encoding and decoding results.
Upload image files up to 50MB with drag-and-drop support and automatic format validation for seamless processing.
All conversion processing happens in your browser using client-side JavaScript. No images are uploaded to servers.
Upload an image file (PNG, JPEG, WebP, GIF, or SVG) and click Encode to Base64. The tool converts your image to Base64 format with options for compression, quality control, and different output formats.
Paste your Base64 string or data URL into the input field and click Decode to Image. The tool validates the Base64 format and converts it back to an image with preview and download options.
The converter supports all major image formats including PNG, JPEG, JPG, WebP, GIF, and SVG. You can encode images up to 50MB with automatic format detection.
