What the tool does
File to Base64 converts any local file into a Base64 string directly in your browser. It supports drag & drop and large files without server involvement.
When to use it
Use it when embedding files into JSON, HTML, CSS, or API requests, or when preparing binary assets for transport in text-only environments.
Quick example
Drop an image file and instantly receive a Base64 string ready to embed in a data URI or API payload.
Security / privacy
Files never leave your device. No uploads, no cloud processing, no retention. This makes it safe for confidential documents, internal assets, or proprietary files.
