.bmp only. Drop several for a batch.

    Standard BMPs are opaque, so a white background is applied only if a file happens to carry transparency.

    How to convert BMP to JPG

    1. Drop your .bmp files onto the drop zone, or click to browse for them.
    2. Choose a quality setting — the default of 0.90 is a good balance of size and detail.
    3. Click Convert to JPG to re-encode each bitmap through the canvas.
    4. Grab a single JPG directly, or a zip if you converted a batch.

    Why convert BMP to JPG?

    BMP is one of the oldest image formats around, and it stores pixels with essentially no compression. That makes it reliable and simple, but also enormous: a single full-screen BMP can be dozens of megabytes, where the same picture as a JPG might be a few hundred kilobytes. If you have inherited BMP files from a scanner, an old Windows program, a screen capture tool or a piece of industrial equipment, converting them to JPG makes them dramatically easier to store, email and upload. Because BMP is uncompressed, this is one of the conversions where you gain the most space, frequently cutting file size by well over 95% for photographic content with almost no visible change. The conversion runs on the HTML canvas entirely inside your browser, so even large bitmaps are handled without an upload and without your images leaving your computer. Most BMP files are fully opaque, so transparency is rarely a concern here, but if a file does carry an alpha channel it is flattened onto white so the JPG looks correct. There is no signup and no watermark — drop your bitmaps and get compact JPGs back in seconds.

    FAQ

    Why are my BMP files so large?

    BMP stores every pixel with little or no compression, so file size scales directly with resolution. JPG compresses the same image far more efficiently, which is why the converted files are so much smaller.

    How much space will I save?

    For photos, the saving is usually dramatic — often 90% or more — because you are moving from an uncompressed format to an efficient lossy one.

    Will the JPG look different from the BMP?

    At a high quality setting the difference is very hard to spot. Fine text or sharp edges compress less gracefully, so lower the quality only if you need smaller files.

    Do my bitmaps get uploaded?

    No. Everything is decoded and re-encoded locally in your browser. Your BMP files never leave your device.
