What You're Handing Over to a Converter
Images people convert to Base64 are often destined for a codebase — a logo, an icon, a screenshot for documentation — but sometimes they're something more sensitive: an unreleased design, a private photo, or a proprietary graphic. If an online converter uploads that image to a server just to encode it, the image leaves your device before you've even gotten the string you were after.
How This Tool Keeps Everything Local
This Base64 Image Converter processes your image entirely using JavaScript inside your own browser tab. Whether you're encoding an image to Base64 or decoding a string back into one, the work happens on your device — nothing is uploaded to a server. This is verifiable, not just a stated claim.
- Check the Network tab: open your browser's developer tools, watch the Network panel, and convert an image — you won't see it uploaded anywhere.
- Disconnect from the internet after the page loads, and convert anyway — it still works, since no server round-trip is involved.
Why This Matters Even for "Just an Icon"
It's easy to assume converting a small icon carries no real privacy stakes — but the same tool is often used for unreleased logos, internal design assets, or screenshots containing sensitive information visible in the frame. Client-side processing means there's no server log of what you converted, no third-party retention policy to trust, and the only copy of your original image stays on your own device throughout.
