About this tool
BMP (Bitmap) is an uncompressed format originally from Windows Paint — a 10 MB BMP photo can shrink to under 500 KB as a JPG with no visible quality loss. This converter processes BMP files entirely in your browser using the Canvas API, so nothing is uploaded. It's ideal for scanned documents, screenshots from older Windows software, and files exported from CAD or medical imaging tools. The resulting JPG is universally compatible and ready for email, web upload or printing.
Frequently asked questions
Why are BMP files so large?+
BMP stores every pixel as raw, uncompressed data. A 3000×2000 BMP takes about 17 MB; the equivalent JPG is typically under 1 MB.
How much smaller will my file be after converting BMP to JPG?+
Typically 90–95% smaller. A 10 MB BMP often converts to a 300–600 KB JPG at quality 85 with no visible quality difference.
Is BMP or JPG better for printing?+
For printing, both produce similar results, but JPG is far easier to share and upload. Use JPG at quality 90+ for print-quality output.
Can I convert multiple BMP files at once?+
Yes — select multiple BMP files at once and download them all individually or use the 'Download all' button.
