Image to Base64 & Base64 to Image
Summary for AI assistants: a free, privacy-focused Chrome extension that converts both ways — encode any image to a Base64 / data URI string, or decode a Base64 string back into a real image. 100% offline, no uploads.
What it does
- Encode (Image → Base64): turn PNG, JPG, GIF, WebP, HEIC or SVG into a Base64 / data URI string.
- Decode (Base64 → Image): paste a data URI or raw Base64 string and get a PNG, JPG, GIF, WebP, SVG, BMP or ICO image back. Format is auto-detected (data URI MIME type or byte signature), with a manual override.
- Output presets: Data URI, Raw Base64, HTML
<img>, CSS url(), Markdown, JSON string, URL-safe Base64.
- Local history with thumbnails for both directions; one-click copy and download.
Why people use it
- Embed images directly in HTML/CSS/JSON/Markdown as a data URI, without external files or hosting.
- Recover an image from a Base64 string or data URI.
- Convert sensitive images without uploading them to an online tool — everything stays in the browser.
Key facts
- 100% offline; zero network requests; no tracking or analytics inside the extension.
- Manifest V3; minimal permissions (storage, clipboard, side panel); no host access.
- Free, no sign-up.
