Why convert BMP to JPG
BMP, the Windows bitmap, is one of the oldest picture formats. It stores every pixel as it is, with no compression, so even an ordinary photo makes a very large file. BMPs still turn up from older scanners, Paint, older software and old archives. Many websites and upload forms refuse them, and their size makes them slow to email. As a JPG, the same picture is far smaller and opens anywhere.
How to convert
- Choose up to 30 BMP images, each up to 50 MB. You can also drop them on the box.
- Leave the quality at 90, or change it (below).
- Press Convert to JPG, then download each JPG, or all of them together as a ZIP.
Choosing the quality
The number, from 1 to 100, sets how much detail the JPG keeps. 90, the default, suits photos and scans: they look the same and the file is a small part of the BMP’s size. JPG smooths over fine detail, so the sharp edges of text, lines and flat shapes can pick up faint smudges, more visible at lower numbers. For screenshots and diagrams, BMP to PNG keeps every pixel and still makes a much smaller file than the BMP.
Your browser reads the BMP
The conversion uses your browser’s own BMP support, which covers the common kinds: black-and-white, 16 and 256 colors, and full color. A rare or damaged file it can’t read gets a message saying so, and the other files still convert. Any see-through areas, which few BMPs have, become white, because JPG has no transparency.
What else to know
- Size in pixels stays the same. To make a big scan smaller in pixels too, use the Image Resizer.
- Names:
scan001.bmpbecomesscan001.jpg. - To aim for a file size, such as under 200 KB for a form, use Compress Image to 200 KB.
