How to use Convert BMP to Base64
- 1. Upload the BMP file. Drop in a bitmap image. Its raw bytes are read directly so they can be re-expressed as text rather than binary.
- 2. The tool encodes it as Base64. There are no settings to choose. The file's bytes are converted straight into a Base64 string that represents the exact same image data as plain text.
- 3. Copy the Base64 output. Copy the resulting string to paste into HTML, CSS, JSON, or anywhere an image needs to travel as text rather than as an attached file.
When to use Convert BMP to Base64
Convert BMP to Base64 encodes a bitmap image as a Base64 string so it can be embedded directly in text-based formats. It is the encoding half of the round trip, turning a binary BMP file into a string you can paste anywhere text is accepted.
- Embedding an icon in CSS. A small bitmap icon needs to live directly inside a stylesheet as a data: URI background image rather than as a separate file the browser has to fetch.
- Storing an image in a database column. A legacy system stores images as text fields rather than binary blobs, and a BMP file needs converting to Base64 before it can be inserted into that column.
- Sending an image through a text-only channel. An API, webhook, or config format only accepts text values, and a bitmap screenshot needs to travel through it encoded as a Base64 string instead of a raw file upload.
