高精細な画像を扱うBMP形式。しかし、ウェブや特定のシステムでの利用、あるいは限られた環境下での表示を考えると、より軽量で柔軟な形式への変換が求められることがあります。XPM形式は、そのシンプルさと拡張性から、特にプログラミングやリソース管理の分野で重宝されてきました。このページでは、お手持ちのBMP画像をXPM形式へとスムーズに変換する方法をご紹介します。複雑な設定は不要。たった数クリックで、あなたの画像を新たな用途で活用できるようになります。漫画のデジタル化からビジネスでの資料共有、あるいは特定の開発プロジェクトでの素材利用まで、幅広いシーンでお役立てください。私たちは、皆様のデジタルワークフローがより快適になるよう、高品質な変換ツールを提供いたします。
- 漫画・イラスト素材の軽量化
- ビジネス資料のアイコン作成
- 組み込みシステム用画像リソース
日本では、特に古いシステムや一部の組み込み機器において、XPM形式が画像リソースとして利用されるケースが現在でも見られます。また、開発コミュニティ内での互換性確保の観点からも、この変換は一定の需要があります。
About BMP to XPM Conversion
BMP (introduced 1986) and XPM are both image formats, but they differ in important ways. BMP is an uncompressed raster format that preserves every pixel but produces very large files. XPM is a widely used file format.
When you convert BMP to XPM, the goal is to convert between formats quickly. Converting BMP to XPM maintains high quality with CocoConvert's optimised encoder settings. Understanding these technical differences helps you choose the right format for your workflow.
Your BMP file is decoded and re-encoded as XPM. The conversion involves 4 steps: (1) your bmp file is uploaded and validated, (2) the file is decoded (parsed into its raw data), (3) the data is re-encoded in xpm format, (4) the converted file is ready for download.
CocoConvert's converter handles the entire pipeline server-side using FFmpeg, Sharp, and qpdf — battle-tested libraries used by streaming platforms and enterprise tools. Files are encrypted in transit and deleted within 24 hours.
This conversion is ideal when you When you need a XPM file. For the opposite direction, CocoConvert also supports XPM to BMP conversion.
How to Convert BMP to XPM
- 1
Upload .bmp file
Select your BMP file by dragging it to the upload zone or using the file picker. Batch upload is available for multiple files.
- 2
Choose .xpm
Set XPM as the output format. The converter uses optimal settings based on the BMP→XPM conversion profile.
- 3
Convert
The server-side engine decodes your BMP file and re-encodes it as XPM. Processing time depends on file size and complexity.
- 4
Download result
Grab your converted .xpm file. Multiple output files can be downloaded together.

Frequently Asked Questions
What is the difference between BMP and XPM?
BMP is an uncompressed raster format that preserves every pixel but produces very large files. XPM is a widely used file format.
Does BMP to XPM conversion affect quality?
Converting BMP to XPM maintains high quality with CocoConvert's optimised encoder settings.
Which format has better compression, BMP or XPM?
BMP uses none compression. XPM is widely supported. The better choice depends on whether you prioritize file size or quality.
How long does BMP to XPM conversion take?
Most conversions finish in seconds. Larger files or complex image content may take 10–30 seconds. CocoConvert processes files in parallel for batch jobs.
Is BMP or XPM better for long-term storage?
BMP is better for archival since it's lossless.
