JPG to BMP Converter
You can turn your JPG and JPEG images into uncompressed Windows Bitmap files right in your browser with this easy JPG to BMP converter. Just upload your JPG, click Convert, and you'll have a pixel-perfect BMP file ready to download in seconds. The workspace handles everything from standard conversions to batch processing, HD quality for color accuracy, and resizing for custom dimensions all in one place. Your images never leave your computer because all the processing happens locally through the Canvas API.
JPG to BMP
Convert individual JPG images into raw, uncompressed BMP bitmap files with zero quality loss and full pixel fidelity.
JPEG to BMP
Accept .jpeg file extensions and produce identical BMP output, covering both common naming conventions.
Batch Convert
Select or drag multiple JPG files and convert them all to BMP in a single operation with individual progress tracking.
HD Quality
Preserve maximum 24-bit color fidelity for archival, print, and scientific imaging workflows.
Resize & Convert
Specify custom width and height with optional aspect ratio lock before converting to uncompressed BMP.
How to Convert JPG to BMP
Converting your JPG images to BMP only takes three quick steps. Start by dragging your JPG files into the workspace or clicking to browse your computer. Once your files are in the sidebar, just click Convert to BMP and your browser handles the rest. Each image is drawn to a local canvas and exported as an uncompressed bitmap without any server processing. You can check the results in the preview panel, toggle between the original JPG and the converted BMP to compare them, and then download your files individually or all at once.
Drag and Drop or Click to Upload
You can drag and drop your files directly into the workspace or click to browse through your computer. Just drop a single file or a whole batch of JPG images to get started. Each file appears in the sidebar with its original size, and once the conversion is done, the BMP file size is shown right next to it for easy comparison.
Preview and Compare Original vs. BMP
After conversion, click any file in the sidebar to open a full-size preview. Toggle between BMP and Original views using the switcher in the preview toolbar. Zoom, rotate, and flip controls let you inspect your converted image from every angle before downloading.
Online JPG to BMP Converter with Batch Processing
Converting large groups of JPG images is quick and easy with batch mode. When you select multiple files at once, each image is processed independently with its own progress tracker and size comparison. If you missed a few files, you can add more to the queue at any time without losing your current progress. Use the Download All BMP button to save every converted file to your device at once, making it simple to process an entire library in minutes.
Resize Before Converting
The Resize and Convert mode lets you specify exact pixel dimensions for your BMP output. Lock the aspect ratio to prevent distortion, or unlock it for custom proportions that match your target application. This is particularly useful when preparing images for legacy systems, embedded displays, or specific hardware that requires exact bitmap dimensions.
HD Quality for Professional Workflows
HD Quality mode preserves every color value from your original JPEG at full 24-bit color depth. This is a must-have for print production, scientific imaging, medical work, and any project where you can't afford to lose color accuracy.
Free JPG to BMP Converter with Browser Privacy
Privacy is built into every part of this converter. All processing happens through your browser's local Canvas API, so your images never leave your computer and you don't need to create an account. Once you close the tab, all session data is cleared from memory. You can even use the converter offline after the page loads since it doesn't need to talk to a server. You won't find any file size limits, watermarks, or conversion caps here.
Why BMP Format Still Matters
Windows Bitmap format stores each pixel as uncompressed RGB data, producing files that are significantly larger than compressed formats like JPG or PNG. Despite this, BMP remains essential in specific domains: legacy Windows applications, industrial control systems, embedded hardware with fixed display buffers, certain scientific instruments, and workflows that require raw pixel access without decompression overhead.
No Watermarks, No Limits, No Account
Every conversion mode is open the moment you arrive. Your files live only in your browser tab's memory for the duration of your session. There are no premium tiers, no hidden fees, and no restrictions on the number of files you can convert or their dimensions.
