Features

Image to Base64 is a free online converter that turns local JPG, PNG, WebP, and SVG files into Base64 data URIs directly inside your browser. Drag files into the drop zone, adjust output format and max-dimension limits, then copy the resulting string or CSS url() snippet straight into an email template, CMS, or stylesheet. Every pixel stays on your device — no uploads, no server logs, and no queue wait.

When You Need This

Common pain points this tool solves

1. Embedding small icons and logos directly into HTML email templates so clients don't have to host or block external image files
2. Turning screenshots and product badges into Base64 strings for inline embedding in a single-file HTML report or knowledge base
3. Generating CSS background-image url() strings for inline SVGs and tiny PNG tiles without extra HTTP requests

How to Use

Step-by-step instructions

1. Drop one or more JPG/PNG/WebP/SVG files onto the upload zone or click to select them from disk
2. Pick the output format: raw Base64 string, HTML img tag, CSS url(), or Markdown image embed
3. Optional: enable resize-by-max-dimension if you want a smaller payload for email or CSS inline use
4. Click to copy the snippet for each file, or batch-copy all results at once for your codebase
