What it does
Base64 image is one of 55 tools in Hexkit, a desktop developer toolbox that runs entirely on your own machine. Convert images to Base64 data URIs and preview them inline.
Because Hexkit is a native app rather than a web page, anything you paste into the base64 image stays local — there are no uploads, no accounts and no telemetry. You can decode tokens and inspect encoded data even with the network turned off, which makes it safe for tokens, keys and production data.

How to use Base64 image
- 1
Open Hexkit and select "Base64 image", or press the command-palette key and start typing its name.
- 2
Paste the text or token you want to encode or decode. Convert images to Base64 data URIs and preview them inline.

Read or copy the result. Everything is computed locally by Hexkit's Rust core, so nothing is ever uploaded.
Tip: the command palette opens any tool in one keystroke.
