How much smaller will the JPG be compared to BMP?

Often 10 times smaller or more, since BMP stores every pixel with no compression at all while JPG compresses the image significantly. A large uncompressed BMP that is awkward to email becomes a lightweight file you can upload or send in seconds.

Is there a quality loss converting BMP to JPG?

JPG is a lossy format, but at high quality settings the difference is invisible in normal viewing, while the file becomes far easier to share and store. For photographic BMP content this trade-off is almost always worth the huge size saving.

When should I choose JPG over PNG from a BMP?

Choose JPG when the BMP is a photograph and a small file matters, such as for email or a website. Pick PNG instead for screenshots, diagrams or text, where lossless compression keeps edges crisp without JPG artefacts.

Where do these large BMP files usually come from?

Old scanners, legacy Windows software and some screen-capture tools still export uncompressed BMP. Converting to JPG makes those bulky files practical to share, upload or archive without special software.

Does the JPG keep any transparency?

A standard BMP is fully opaque with no alpha channel, so there is normally nothing transparent to lose. JPG has no transparency support either, so opaque images convert cleanly with no white-box surprises.

Will the JPG print at the same quality?

Yes. At high quality settings the print looks identical to the BMP, because the size reduction happens in the stored file bytes, not in the pixel resolution used for printing.

Can I convert several BMP files to JPG at once?

Yes. Add a whole folder of BMP files and each becomes its own compact JPG in a single pass, with nothing merged and no limit on the number of files.

About BMP and JPG

Key things to know before you convert BMP to JPG:

BMP

BMP is an uncompressed legacy Windows bitmap. Huge files with no benefits today; kept around for old software compatibility.

JPG

JPG (JPEG) has been the default photo format since 1992. Lossy compression keeps photographs small, and literally every device and program can open it. It does not support transparency or animation, and every re-save loses a little quality.
