Why ToFormat?
Superior Compression
HEIF uses advanced compression algorithms to shrink BMP files by up to 50% or more. Store more images with less space, perfect for archives and mobile devices.
Modern Feature Set
HEIF supports high bit depth (10/12/16-bit), HDR, lossy and lossless compression, transparency, and image sequences – all in one container.
Batch Processing
Upload up to 20 BMP files at once. We'll convert them all to HEIF and package in a ZIP for easy download.
About the Formats
🖼️ What is BMP?
BMP (Bitmap) is a raster graphics format developed by Microsoft. It stores pixel data uncompressed (usually), resulting in large files but exact fidelity. It's the simplest format, supported everywhere, but impractical for web use due to size.
All BMP conversion tools →📱 What is HEIF?
HEIF (High Efficiency Image File Format) is a modern container format developed by MPEG. It uses HEVC (H.265) compression to achieve about half the file size of JPEG at the same quality. HEIF supports animations, HDR, transparency, depth maps, and burst photos. It's the default format for Apple devices (iOS 11+) and is gaining web support.
All HEIF conversion tools →How to Convert
Upload your BMP
Click or drag and drop your BMP files. You can select up to 20 at once.
Choose HEIF settings
Select quality (lossy or lossless). For photos, quality 80-90% gives excellent results at half the size. Enable HDR if your source supports it.
Download HEIF
Your HEIF files are ready. Download individually or as ZIP. Files auto‑delete in 10 minutes.
When to Convert BMP to HEIF
📱 Mobile & Apple Devices
HEIF is the native format on iOS. Convert BMP to HEIF for seamless sharing and storage on iPhone, iPad, and Mac.
💡 Need JPEG for compatibility? Try BMP to JPG →💾 Storage Optimization
Archive your BMP collection in HEIF format. Save gigabytes of disk space while keeping the ability to convert back when needed.
💡 For lossless archive: BMP to PNG →🌐 Web Performance
Use HEIF on modern websites for faster loading. Supported in Safari and via plugins in Chrome. Perfect for high-quality image delivery.
💡 Wider support: BMP to WebP →📸 Photography
Photographers can store RAW edits or high-bit-depth images in HEIF with 10/12-bit color. Maintain professional quality with smaller files.

💡 Pro Tips
- Use lossy HEIF for photos – at quality 85%, files are often 40-50% smaller than BMP with no visible difference.
- For lossless preservation of graphics, choose lossless HEIF mode. It outperforms PNG in compression while maintaining perfect fidelity.
- HEIF supports HDR and wide color gamut (P3, Rec.2020). If your BMP has HDR data (rare), enable HDR mode to preserve it.
- Convert in batch mode – upload multiple BMPs and download all HEIFs as a ZIP archive. Great for photo libraries.
- We strip metadata by default for privacy, but you can keep EXIF by toggling the option. HEIF can store extensive metadata.
- HEIF files can also contain image sequences – like live photos or bursts. This is preserved if your BMP sequence is uploaded in order.
- For web use, consider providing a fallback format (JPG/WebP) for older browsers that don\'t support HEIF.
How BMP to HEIF Conversion Works
BMP stores raw pixel data without compression, resulting in large files. HEIF is a container that uses modern compression algorithms (typically HEVC/H.265) to encode image data efficiently. When you convert, our server decodes the BMP to raw pixels, then encodes them using the HEIF codec with your chosen quality settings. The result is a dramatically smaller file that retains excellent visual quality.
All processing is done in memory, and your files are permanently deleted after 10 minutes.
BMP vs HEIF: Key Differences
Compression: BMP is uncompressed → huge files. HEIF uses advanced compression (HEVC) → up to 50% smaller.
Color depth: BMP up to 24-bit; HEIF supports 8/10/12/16-bit per channel, HDR, and wide color gamuts.
Features: HEIF supports animations, transparency, depth maps, image sequences; BMP is static and flat.
Compatibility: BMP works everywhere; HEIF is native on Apple devices, supported in Safari, Edge, and via extensions in Chrome/Firefox.
When to Convert BMP to HEIF
Convert BMP to HEIF when you need modern, space-efficient storage – especially for photo libraries, mobile apps, and websites targeting modern browsers. HEIF is ideal for high-quality images where file size matters. Always keep the original BMP for maximum compatibility with legacy software.
Our HEIF to BMP converter lets you revert to BMP when needed.
