IMAGE FORMAT GUIDE

BMP explained.

BMP is a bitmap format commonly associated with Windows applications. Converting a BMP to PNG or JPG can make it more convenient to share or publish online.

When to choose BMP

Choose BMP to PNG to store the decoded pixels losslessly in a more practical container. Choose BMP to JPG for photographic content when smaller files and upload compatibility matter. To create a BMP for an older workflow, use JPG or PNG to BMP.

What to expect

Pixrelio reads common uncompressed Windows BMP files and 16-bit or 32-bit bitfield BMP. RLE-compressed BMP and OS/2 variants are not supported. BMP output is always an uncompressed Windows 24-bit bitmap and can be much larger than the source.

Choose the right alternative

Choose a background color before exporting BMP, because 24-bit BMP output is opaque. PNG is usually a better option for transparency or web graphics. Saving a JPG as an uncompressed BMP does not restore detail lost in the JPG.

Support in Pixrelio

Import supported BMP variants and export standard 24-bit BMP. Pixel dimensions are retained. File and output-batch limits still apply, so a large bitmap may require a smaller batch.
