File to Base64 Encoder
Convert a small file into a Base64 data string or data URL.
Base64 turns a binary file into ordinary text, which is how small images are embedded in stylesheets, how attachments travel inside email and API payloads, and how a logo can be inlined without a second network request. This encoder reads a file you choose and produces either the raw Base64 string or a complete data URL including the media type. Keep files small: Base64 adds roughly a third to the size, and very large files will strain the browser. Encoding uses the browser's own file reader, so the file itself is never uploaded to docvexa.fun or anywhere else.
How to use the File to Base64 Encoder
- Choose a small file, such as an icon, a font or a short PDF.
- Select whether you want a raw Base64 string or a full data URL.
- Press Encode File, then copy the output.
Your files stay with you
This page carries out its work inside your browser. The file you choose is read locally, processed in memory and returned to you as a download; it is not transmitted to docvexa.fun and no copy is kept once you leave the page. Results are produced automatically and should be checked before you rely on them for anything important.
