BMP vs HEIF — Comparison & Free Converter
Fast, instant BMP to HEIF conversion. No signup required. Just drop your .bmp file and get .heif in seconds.
Batch Settings
Quality reduction ahead
BMP is uncompressed, meaning every bit of data is preserved. HEIF uses lossy compression — some data is permanently discarded to reduce file size. At high quality settings the difference is usually imperceptible, but the original data cannot be recovered.
Color depth reduction: 32-bit → 10-bit
BMP stores up to 32 bits per channel, but HEIF supports only 10 bits. You may notice banding in smooth gradients (like sky or skin tones) where subtle color transitions are lost.
What compression artifacts to expect
HEIF lossy compression can produce blurring and occasional color shifts. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.
About BMP to HEIF Conversion
BMP or HEIF — which format should you use? The answer depends on your needs. Here's a quick breakdown.
BMP is an uncompressed raster format that preserves every pixel but produces very large files. It has universal platform support. HEIF stores images using highly efficient HEVC compression, commonly used on Apple devices. It has limited platform support.
Full Name: BMP uses Bitmap Image, while HEIF uses High Efficiency Image Format. Compression: BMP uses None (uncompressed), while HEIF uses Lossy. Transparency: BMP uses No, while HEIF uses No.
So when should you convert BMP to HEIF? This conversion is ideal when you Your BMP file is too large for email attachments or upload limits, or when you You want to reduce storage usage without noticeably affecting quality. This conversion helps you reduce file size without visible quality loss.
HEIF lossy compression can produce blurring and occasional color shifts. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.

Select .heif from the output options. The converter applies optimal quality settings automatically.
- 3
Run the conversion
Click Convert. Server-side processing means your device stays fast — even for large image files.
- 4
Get your HEIF file
Download your converted file instantly. Batch downloads are available as a zip archive.
What Happens When You Convert BMP to HEIF
Your BMP image is decoded into raw pixel data, then re-encoded as HEIF. Some quality is permanently lost during compression. CocoConvert uses high-quality defaults to minimize this.
Your BMP file is decoded — the compressed/stored pixel data is expanded into raw RGB pixels
Pixels are re-encoded using High Efficiency Image Format's lossy compression algorithm
Metadata (EXIF, ICC profiles) is transferred where HEIF supports it
The HEIF file is saved and ready for download

Frequently Asked Questions
Should I use BMP or HEIF?
It depends on your goal. BMP preserves full quality. HEIF offers smaller files via lossy compression. Choose based on whether file size or quality matters more for your use case.
Is HEIF higher quality than BMP?
Not necessarily. HEIF lossy compression can produce blurring and occasional color shifts. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes. Quality depends on the compression type and settings, not just the format name.
Can I convert BMP to HEIF on Mac and Windows?
Yes. CocoConvert is a web-based tool that works in all modern browsers — Chrome, Safari, Firefox, Edge — on any operating system including macOS, Windows, Linux, iOS, and Android.
Is CocoConvert free for BMP to HEIF?
Yes. Free users get 5 conversions per hour (250 MB each). Pro subscribers unlock 100 files per hour, 5 GB per file, and priority processing.
What tools does CocoConvert use for BMP to HEIF?
CocoConvert uses FFmpeg for audio/video, Sharp for images, and qpdf for documents — the same open-source libraries used by Netflix, YouTube, and major enterprise platforms.
