BMP stores three bytes per pixel and compresses nothing, which is why bitmaps out of a scanner, MS Paint or an old Windows program are absurdly heavy for what they show: 36 MB for a 12-megapixel image, 24 MB for a full-page scan. As a JPG at quality 85 the same picture is typically 1–3 MB. PIXLFLW converts it in your browser — worth knowing, because a 36 MB upload to a conversion site is a slow way to find out it worked.
Why convert BMP to JPG here
- No upload — the file that would take minutes to send is read locally, in a moment.
- Quality you pick — the slider and the resulting size sit next to each other; scans of text usually want 85–90, photographs are fine at 80.
- An exact byte budget — if the portal you are feeding has a 2 MB rule, type 2000 KB and the encoder finds the quality that fits.
- Resize while you are at it — scanner output is often far larger than anything needs.
How to convert BMP to JPG
- Drop the .bmp file into the upload area above.
- The editor opens with JPG already picked as the export format.
- Set quality, check the size, save.
If the bitmap is line art, a diagram or a screenshot of text, consider PNG instead: JPG smudges sharp edges, and PNG will compress that kind of image far better than it compresses photographs. Both are in the same export menu.
