Free BMP to JPG Converter
SmarterSources's BMP to JPG converter transforms uncompressed bitmap files into optimized JPEG images directly in your browser. BMP (Bitmap) files store raw pixel data without any compression, resulting in enormous file sizes. A single 1920×1080 BMP image can easily be 6 MB or more. Converting to JPG typically reduces file size by 90-95% while maintaining excellent visual quality.
Why Convert BMP to JPG?
BMP files are uncompressed raster images that take up far more storage than necessary. They are impractical for email attachments, web uploads, and general sharing. JPG (JPEG) uses lossy compression to dramatically shrink file sizes while keeping the image looking virtually identical. If you have screenshots, scanned documents, or photos saved as BMP, converting to JPG is the fastest way to reclaim storage space and make your files easy to share.
How It Works
Drop your BMP files into the tool above, adjust the quality slider to control the compression level, and click Convert All. Each BMP image is decoded, drawn onto an HTML5 canvas with a white background, and re-encoded as a JPEG at your chosen quality setting. The entire process runs locally in your browser — no files are ever uploaded to a server.
Privacy Guarantee
SmarterSources processes your BMP files entirely within your browser using the Canvas API. No files are uploaded to any server. Your images never leave your device, making this the most private BMP to JPG converter available online.
Frequently Asked Questions
How much can I reduce file size by converting BMP to JPG?
BMP files are uncompressed, so the savings are dramatic. A typical BMP image can be reduced by 90-95% or more when converted to JPG at the default quality setting (92%). For example, a 6 MB BMP file might shrink to 300-600 KB as a JPG with no perceptible quality loss.
Does converting BMP to JPG lose quality?
JPG uses lossy compression, which means some image data is discarded. However, at quality settings of 85-95%, the difference is virtually imperceptible to the human eye. The quality slider gives you full control: higher values preserve more detail, lower values produce smaller files. For most photos and screenshots, the default 92% is an excellent balance.
When should I keep my images as BMP?
BMP is useful in specific workflows that require completely uncompressed pixel data, such as certain scientific imaging, legacy software integrations, or professional editing pipelines where every re-encoding step matters. For everyday use — web, email, social media, presentations — JPG is far more practical.
Can I convert multiple BMP files at once?
Yes! Drag and drop multiple BMP files or select them with the file picker. All files will be converted with the same quality settings, and you can download them individually or all at once. There is no limit to the number of files you can convert in a single batch.
Is my data safe? Are files uploaded anywhere?
Your files never leave your device. All conversion happens 100% in your browser using JavaScript and the HTML5 Canvas API. No data is sent to any server. You can even use this tool offline once the page has loaded.
