Convert bitmap image files

A raw, uncompressed Windows bitmap. Big, blunt and impossible to get wrong. A header followed by raw pixel rows, usually with 24 bits of colour per pixel and no compression at all. That is the format you end up with when something needs to look the same on every screen, which is why it keeps turning up in a screenshot from an old windows tool. From here it can become PDF, PNG and JPG, and the conversions run on your own device, so the file is never uploaded anywhere.

    About the format

    A raw, uncompressed Windows bitmap.

    A header followed by raw pixel rows, usually with 24 bits of colour per pixel and no compression at all.

    Where it is good
    • No compression means no artefacts, ever
    • Trivial to read, so almost any program can open it
    • The historical native format of Windows
    Where it falls short
    • Enormous — a 4000×3000 photo is around 35 MB
    • Almost nobody accepts it for upload or download
    • Loses every bit of metadata on the way
    You will find it on
    Legacy Windows software, graphics libraries, print drivers

    The thing people miss

    BMP is roughly ten times larger than the same image as PNG.

    How to

    Converting a BMP file

    1. 01

      Add your bitmap image

      Drag the file onto the drop zone, or tap to browse. Only one file is needed.

    2. 02

      Pick what you want it to become

      Every format this file can become is listed in the switchboard. Pick one and the converter opens with sensible defaults already set.

    3. 03

      Download the result

      Your converted file downloads straight to your device. Nothing was uploaded, so there is no file to delete from a server afterwards.

    Questions

    BMP conversion questions

    How do I convert BMP to another format?

    Add your bitmap image file to the drop zone, choose the target format, adjust the options if you want to, and press convert. The finished file downloads immediately.

    Is my file uploaded anywhere?

    For most conversions, no. They run entirely inside your browser tab. The file is read from your device and the result is written back to your device.

    Do I need an account?

    No. There is no signup step, no email capture and no usage counter. Open the tool, convert the file, close the tab.

    Will there be a watermark or a page limit?

    Neither. On-device conversions produce a clean file with no branding and no cap on pages, size or number of files.
