BMP files are uncompressed, which makes them huge: a single screenshot or scan can be tens of megabytes. They usually come from older Windows software, Paint, scanners and industrial equipment. pdfty's BMP to JPG converter turns them into compact JPGs you can email, upload to a website or store without filling your drive.
Conversion runs on our server with Pillow and saves at quality 85, which typically cuts file size by 90% or more with no visible difference for photos and scans. If a BMP contains transparency, those areas become white because JPG cannot store it. For screenshots with small text where every pixel matters, consider PNG instead.
Upload several BMPs at once and get a ZIP with one JPG per file. Free: no daily limit, up to 20 MB per file, no watermark, no sign-up. Files are deleted within 1 hour. Scanned documents that need to stay together can go straight into JPG to PDF after conversion.
Drag and drop one or more .bmp images. Up to 20 MB each free.
Each image is compressed to JPG at quality 85.
One file gives one JPG; several files arrive as a ZIP.
Expect the JPGs to be a small fraction of the BMP size.
Uploads and results are deleted from our servers within 1 hour.
