ICO → BMP

Learn about the formats: What is BMP? What is ICO?

Convert your ICO icon files to the BMP format effortlessly with our online tool. This conversion is ideal for users who need to extract high-quality raw image data from Windows icons for further desktop editing or software development.

An ICO file is a specialized container format designed for Windows icons, often containing multiple resolutions and color depths within a single file. BMP, or Bitmap, is a standard raster graphics format that stores pixel data in an uncompressed or minimally compressed state. When converting from ICO to BMP, the tool extracts the specific image layer and translates its pixel grid into the simple, structure-heavy BMP format, which is widely recognized by legacy Windows applications and basic image editors.

Since both ICO and BMP are raster formats, the conversion process is lossless. You retain 100% of the visual fidelity of the original icon pixel data.

Tips

Be aware that BMP files lack transparency support; your icon's transparent background will turn into a solid color, usually white or black.
Expect the file size to increase significantly because BMP does not utilize the complex optimization routines found in ICO files.
Choose the highest resolution layer from the ICO file if it contains multiple sizes.

Common use cases

Preparing icon assets for legacy software development that requires raw bitmap input.
Converting system icons for use in high-resolution design mockups where transparency isn't needed.
Extracting specific icon frames to use as textures in older 2D game engines.

🖼️

Images

Raster and vector graphics for web, print, and photography.

Common extensions: PNG, JPG, WebP, AVIF, GIF, SVG, HEIC, TIFF

Advantages

+ WebP and AVIF offer excellent compression for the web
+ PNG keeps transparency and sharp edges
+ SVG scales without quality loss

Disadvantages

− RAW and TIFF files are large and slow to share
− JPEG loses quality on every re-save
− Some formats are not supported in older browsers

📄

Documents

Office files, PDFs, ebooks, and plain text.

Common extensions: PDF, DOCX, XLSX, PPTX, ODT, EPUB, TXT

Advantages

+ PDF locks layout for printing and sharing
+ DOCX and ODT are easy to edit collaboratively
+ Plain text works on any device

Disadvantages

− PDF is hard to edit without special tools
− Complex layouts may shift after conversion
− Scanned PDFs need OCR for editable text

🎬

Video

Clips, streams, screen recordings, and movies.

Common extensions: MP4, WebM, MOV, MKV, AVI, MPEG

Advantages

+ MP4 (H.264/H.265) plays almost everywhere
+ WebM is efficient for web embedding
+ MKV can hold multiple audio and subtitle tracks

Disadvantages

− High-resolution video needs lots of storage and bandwidth
− Re-encoding always takes time and may reduce quality
− Some codecs require licensing for commercial use

🎵

Audio

Music, podcasts, voice recordings, and sound effects.

Common extensions: MP3, WAV, FLAC, OGG, AAC, M4A, OPUS

Advantages

+ FLAC and WAV preserve full quality for editing
+ MP3 and AAC are universally compatible
+ OPUS delivers great quality at low bitrates

Disadvantages

− Uncompressed WAV files are very large
− Lossy formats cannot be restored to original quality
− DRM-protected files may not convert

Frequently asked questions

No, because both ICO and BMP are raster-based formats, the pixel information is preserved perfectly without degradation.

BMP is a largely uncompressed format that stores pixel data in a simple, bulky structure, whereas ICO formats are optimized for small storage footprints.
