    Convert BMP to JPG — Free, 100% Local

    BMP is an early Windows bitmap format that stores images with essentially no compression, so files are enormous — a single full-screen capture easily runs to several megabytes and blows past email and upload-form size limits. Converting to JPG typically cuts the file by more than 90%, making it the most practical first step for old scans, Paint exports and surveillance captures.

    JPG is a lossy format; this tool exports at 92% quality, which is visually indistinguishable for typical photos and screenshots. If your BMP is a UI capture packed with fine text and must stay lossless, BMP to PNG is the better choice.

    Frequently Asked Questions

    Will my images be uploaded?

    No. Conversion runs entirely in your browser using the Canvas API — 100% local processing. Your images are never uploaded to any server.

    How much smaller will the JPG be?

    Because BMP is essentially uncompressed, converting to JPG usually shrinks the file by more than 90%. The tool shows a before/after size comparison instantly.

    Does converting to JPG lose quality?

    JPG is lossy. This tool exports at 92% quality, nearly indistinguishable for typical content, though screenshots with fine text or sharp lines may show slight artifacts — convert to PNG in that case.

    Is BMP transparency preserved?

    Most BMP files carry no transparency to begin with, and JPG doesn't support it either, so any transparent area is filled with white. Use BMP to PNG if you need transparency.
