Frequently Asked Questions
BMP (Bitmap) is an uncompressed raster image format developed by Microsoft. It stores pixel data without compression, resulting in large file sizes but perfect quality preservation.
BMP is useful when you need uncompressed image data for specific applications, legacy software compatibility, or when absolute quality preservation is required for further editing.
Yes, BMP files are significantly larger because they store uncompressed pixel data. A typical BMP can be 5-10x larger than an equivalent JPG file.
BMP has limited transparency support. While some BMP variants support alpha channels, most applications do not handle BMP transparency. Use PNG for reliable transparency.
You can convert JPG, PNG, WEBP, GIF, TIFF, HEIF/HEIC, SVG, ICO, AVIF, PSD, RAW and many more formats to BMP.
Pro Tips
Large File Sizes
BMP files are uncompressed and can be very large. Only use BMP when you specifically need uncompressed data.
Legacy Compatibility
BMP works great with older Windows software and applications that require uncompressed image input.
Editing Workflow
BMP can be useful as an intermediate format when editing, since no quality is lost between saves.
Modern Alternatives
For lossless quality with smaller files, consider PNG or TIFF instead of BMP.
