Convert text into an uncompressed 24-bit BMP (bitmap) image file.

How do you convert text to a BMP image?

BMP is the odd one out: browsers cannot export it natively, so after drawing your text on a canvas, NMSnabbit reads the raw pixel data and writes a 24-bit uncompressed bitmap byte by byte, headers included. The resulting .bmp is large but dead simple, which is why legacy Windows software and embedded displays still consume it happily. Background colour is required since 24-bit BMP has no alpha.

How to use the Text to BMP

  1. 1 Provide the text for the bitmap.
  2. 2 Select font size along with foreground and background colours.
  3. 3 Inspect the canvas rendering.
  4. 4 Hit Download BMP for the .bmp file.

What you can use it for

  • Producing BMP assets for legacy software.
  • Creating uncompressed bitmaps for embedded displays.
  • Saving text in a plain, lossless format.
  • Generating test bitmaps for image pipelines.

Frequently asked questions

How can a browser export a real BMP?
By hand. The tool pulls raw RGBA pixels off the canvas with getImageData, then assembles the 54-byte BMP header and bottom-up BGR pixel rows itself, producing a spec-correct file.
Why are BMP files so large?
Three bytes per pixel, zero compression. An 800×200 bitmap costs about 480 KB where a PNG of the same text might be 5 KB. The payoff is that almost anything can parse it.
Does the BMP support transparency?
Not in the 24-bit flavour this tool writes; there is no alpha channel to store. Choose a background colour that matches the destination, or switch to PNG for real transparency.
