FAQ
- Why are BMP files so large?
- BMP normally stores pixel values with no compression at all. The file size is essentially width × height × 3 bytes, so a single 1,920×1,080 image runs to about 6 MB. As a JPG the same image drops to a few hundred kilobytes.
- Does quality suffer?
- JPG is lossy, so the result is not identical to the original. For photographs, the difference at quality 0.92 is hard to see. For screenshots full of text and shapes, though, you will get smearing along the edges — convert those to PNG instead.
- Will BMPs from very old software work?
- Any ordinary BMP your browser can read converts fine. Files using very old RLE compression or unusual colour tables may fail to load. In that case, re-save as a standard BMP or PNG in the original program and try again.
