BMP to JPG free
BMP files from old scanners, Windows Paint and some industrial cameras are uncompressed, which is why a single page can be 20 MB. This page converts BMP to JPG on your device at the quality you choose; a typical scan drops to a few hundred KB with no visible change.
Drag the handle. Zoom your browser (Ctrl +) to inspect fine detail at 100%.
Ten to twenty times smaller
BMP stores every pixel raw; JPG compresses photos and scans efficiently. Expect a 20 MB page to become 500 KB to 1.5 MB.
Quality you control
Best, Balanced or Small presets, or an exact KB target for an upload limit.
Batch and private
Fifty files at once, as a ZIP, with nothing leaving your device.
Frequently asked questions
Will the scan still be readable?
Yes. At Best or Balanced quality, text and lines on a scanned page are indistinguishable from the BMP.
Should I pick PNG instead for screenshots?
For screenshots, diagrams and anything with flat colour and sharp edges, PNG is lossless and often smaller than JPG; choose PNG as the output format.
Can I convert BMP to PDF?
Convert to JPG here, then use Image to PDF on this site to place the pages into one PDF.
Is anything uploaded?
No. The file is processed in your browser on your own device. Nothing is sent to a server, nothing is stored, and it works offline once the page has loaded.
