What BMP to PDF conversion does

Convert a BMP image into a single-page PDF directly in your browser, with configurable page size, orientation, fit, and margins.

How to convert BMP to PDF

1. Choose a BMP file.
2. Pick a page size, orientation, fit, and margin.
3. Select Convert & download.
4. Save the .pdf file from your browser downloads.

Why use this conversion

PDF is a universally readable document format for sharing, printing, or archiving a single image without requiring an image viewer.

Transparency and output quality

The image is embedded in the PDF as PNG data, so an alpha channel from the source is preserved inside the document. The embedded image uses PNG compression; overall file size depends mainly on the image content and the page size and margins you choose.

Privacy and local processing

• Processing occurs locally in the browser.
• Files are not uploaded to Looty Tools for conversion.
• Converted files remain on your device.

Limits and known issues

• Input: BMP (.bmp) only, up to 25.0 MB and 8,192 px per side.
• This tool places exactly one image on one PDF page. For combining several images into one multi-page PDF, use the dedicated Images to PDF tool.
• Transparency is kept only when the browser decodes a real alpha channel from the source BMP; most BMP files have no transparency.
• Metadata is not preserved in the downloaded file.

BMP to PDF FAQ

Why convert BMP to PDF?

PDF is a universally readable document format for sharing, printing, or archiving a single image without requiring an image viewer.

Does PDF output keep transparency?

The image is embedded as PNG data, so an alpha channel from the source is preserved inside the document.

Can I combine multiple images into one PDF?

This tool places exactly one image on one PDF page. Use the dedicated Images to PDF tool to combine several images into one multi-page PDF.

Does the source BMP actually have transparency?

Rarely. Most BMP files have no alpha channel at all. When the browser does decode real alpha data from a 32-bit source BMP, it is preserved in output formats that support transparency.

Are my files uploaded?

No. Conversion runs locally in your browser and does not upload your file to Looty Tools servers.

What is validated before conversion?

The file must actually be a BMP — the tool checks the "BM" header bytes, not just the filename or extension, before decoding.
