Decode Base64-encoded image strings back to viewable PNG / JPG / GIF / WebP images — free and instant.
Paste a Base64-encoded image string (with or without the data:image/...;base64, prefix) and instantly preview the image, then download it as a PNG, JPG, GIF, or WebP file. Useful for inspecting embedded images in CSS, HTML, JSON payloads, and email source.
Base64 image encoding lets you embed an image directly in an HTML, CSS, or JSON document instead of linking to an external file. The image bytes are converted to ASCII text using the Base64 alphabet, prefixed with a data URI like data:image/png;base64,iVBORw0KGgo....
Auto-detects the image format from the data URI prefix.
Strips the prefix automatically if pasted with one.
Live preview before download.
Download as PNG, JPG, GIF, or WebP.
No upload — decoding happens entirely in your browser.
Extracting embedded images from email source code. Inspecting Base64 image responses from APIs. Converting design mockups containing inline images into separate asset files. Debugging data-URI usage in CSS and HTML.
Base64 inflates file size by ~33% compared to raw binary. Inline Base64 images make sense for very small assets (icons, spacers); for anything larger, link to a separate image file for better caching. The data: URL scheme has length limits in some contexts (HTML attribute value, ~1024-2100 chars depending on parser).
