BMP, explained.
Uncompressed 24-bit bitmap. Larger, widely compatible files.
Use a bitmap when the destination needs one
BMP is useful for an older application or a workflow that specifically expects bitmap input. FormatPlease exports uncompressed 24-bit RGB BMP. It is usually an inconvenient choice for constrained uploads because each decoded pixel needs storage; compare a supported compressed format instead of assuming BMP improves a photo.
Transparency and specialized variants
This BMP output has no alpha channel or quality slider. Transparent areas use your chosen background, white by default. The browser decodes input BMP files; unusual or damaged variants may fail. Output does not preserve source layers, palette organization or high-bit-depth samples.
A practical workflow
- Confirm that BMP is actually required, then choose a conversion in the BMP tools hub.
- Review the decoded preview and choose a background when the source has transparency.
- Download the bitmap and test it in the destination application; retain the original source.
What you can do here
- Input: supported.
- Output: supported.
- Transparency in output: filled with white.
- Quality control: no quality slider.
GIF offers first/all frame extraction. TIFF supports all/selected pages; PDF renders selected pages separately. Other animated sources export a still frame with a warning. EXIF metadata is removed from converted images.
Common questions
Will BMP make an old compressed photo clearer?
No. BMP stores the decoded pixels; it cannot recover detail lost in the original image.
