HEIF to BMP Converter

Convert HEIF and HEIC images to BMP format online for free. HEIF is the default photo format on iPhone and iPad. BMP provides uncompressed, high-quality output perfect for Windows applications and image editing. Also try our HEIC to JPG converter for smaller file sizes.

How to Convert HEIF to BMP

  1. Upload your HEIF/HEIC images by dragging and dropping or clicking the upload area. You can select up to 10 files at once from your iPhone, iPad, or Mac.
  2. Choose color depth: Select 24-bit for standard true color or 32-bit if you need alpha channel support for transparency.
  3. Optionally resize: Enable resizing to reduce file size. BMP files can be quite large at full resolution.
  4. Convert and download: Click convert and download individual files or all as a ZIP archive.
Pro tip: Use our HEIC Analyzer to check your image properties first. For web use, consider HEIC to JPG for much smaller files.

HEIF vs BMP Comparison

HEIF/HEIC

High Efficiency Image Format developed by MPEG. Default on iPhone since iOS 11. Offers 50% smaller files than JPEG with similar quality. Supports transparency, animation, and multiple images. Limited compatibility with Windows and older software. Use our HEIC to PNG converter if you need transparency.

BMP

Bitmap format native to Windows. Stores uncompressed pixel data for maximum quality with no artifacts. Universal compatibility with all Windows applications and image editors. Large file sizes due to no compression. Ideal for image editing workflows and legacy systems.

Understanding BMP Color Depth

24-bit

True Color - Most Common. Stores 8 bits each for Red, Green, and Blue channels. Supports 16.7 million colors. Compatible with virtually all software. Best choice for photos and general use.

32-bit

True Color + Alpha. Adds an 8-bit alpha channel for transparency. Useful when converting images with transparent backgrounds. Larger files but preserves any transparency from source. Similar to PNG format capabilities.

When to Use BMP Format

Windows Applications

Native Windows format with perfect compatibility. Ideal for older software, system icons, and Windows development.

Image Editing

Uncompressed format preserves all detail. Perfect as a working format before final export. Try our Image Enhancer for improvements.

Printing

Maximum quality without compression artifacts. Good for archival prints where file size doesn't matter.

Legacy Systems

BMP works everywhere. Perfect for older software, embedded systems, and applications requiring raw pixel access.

Frequently Asked Questions

HEIF (High Efficiency Image Format) and HEIC (High Efficiency Image Container) are modern image formats developed by MPEG. Apple adopted them as the default photo format on iPhone and iPad starting with iOS 11 because they offer about 50% smaller file sizes than JPEG while maintaining the same quality. However, they have limited compatibility with Windows and older software, which is why converters like this one are useful.

BMP stores raw, uncompressed pixel data. Each pixel requires 3 bytes (24-bit) or 4 bytes (32-bit). A 12-megapixel iPhone photo would be about 36MB as a 24-bit BMP. This ensures maximum quality but results in large files. If file size is a concern, consider our HEIC to JPG or HEIC to PNG converters instead.

Use 24-bit for most purposes - it's the standard for photos and widely compatible. Choose 32-bit only if your source image has transparency that you need to preserve, or if your target application specifically requires an alpha channel. Note that standard photos from iPhone don't have transparency, so 24-bit is usually the right choice.

Yes! Simply upload your .HEIC files from your iPhone photos. You can AirDrop them to your computer, use iCloud, or connect via USB and browse the DCIM folder. Our converter handles all HEIF/HEIC variants including those with Live Photo data. For batch conversion of many photos, our HEIC to JPG converter might be faster due to smaller file sizes.

Yes, each file can be up to 25MB and you can upload up to 10 files at once. This accommodates high-resolution iPhone photos (typically 2-5MB each as HEIF). If you have many files, convert them in batches. Note that resulting BMP files will be significantly larger than the originals.

Files are temporarily stored only during conversion and automatically deleted within 24 hours. We don't keep copies of your images or use them for any other purpose. For maximum privacy, we recommend downloading your converted files immediately and clearing your browser cache afterward.
