How much smaller will the file be?

Dramatically — BMP is nearly uncompressed, so JPG is often 10× smaller or more.

Will I notice quality loss?

At a high quality setting, no — the difference is imperceptible for photographs.

Should I use JPG or PNG for graphics?

For text or sharp edges, PNG stays crisp; JPG is best for photos.

What is BMP?

BMP is an old Windows bitmap format that stores pixels with little or no compression. Files are large and clumsy to share, though the image data itself is pristine.

Why convert BMP to JPG?

JPG compresses photographic bitmaps into a fraction of the size while staying universally compatible — ideal when a BMP is too big to email or upload.

Quality & compatibility notes

At 85% or higher the JPG looks identical to the BMP for photos while shrinking the file enormously. For sharp graphics or text, consider PNG instead.
