How to Convert HEIC to BMP — Quick & Free
Fast, instant HEIC to BMP conversion. No signup required. Just drop your .heic file and get .bmp in seconds.
Batch Settings
HDR data will be tone-mapped
Your HEIC file may contain HDR (High Dynamic Range) data. BMP only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.
Converting to BMP won't restore lost quality
Your HEIC file has already undergone lossy compression. Converting to BMP preserves what's left — it prevents further degradation from re-saving — but it will not magically sharpen a blurry image or recover discarded audio frequencies.
Animation frames will be lost
HEIC supports animation, but BMP does not. Only the first frame (or a representative frame) will be preserved. If you need animation, consider converting to WebP or GIF instead.
Some metadata may not survive
Your HEIC file may contain EXIF, XMP metadata. BMP has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
Wide color gamut → sRGB
Your HEIC file uses a wide color gamut (Display P3, sRGB). BMP uses standard sRGB. Highly saturated colors outside the sRGB range will be clipped or compressed — this is most noticeable in vivid reds, greens, and blues.
Default format on iPhone 7+ (iOS 11+)
Your device saves files in HEIC by default (iPhone 7+ (iOS 11+), iPad Pro 2017+, macOS High Sierra+). Most people convert because the files won't open on other devices — BMP is universally supported and will work everywhere.
About HEIC to BMP Conversion
Short answer: yes, you can convert HEIC to BMP online for free, and some quality differences may occur depending on the format types. Just upload your .heic file to CocoConvert, pick BMP as the output, and click Convert. The whole process takes seconds.
Now for the details. HEIC (High Efficiency Image Container) is Apple's format for iPhone photos, offering twice the compression of JPEG. BMP is an uncompressed raster format that preserves every pixel but produces very large files. Converting between these two formats lets you improve file compatibility across devices.
Full Name: HEIC uses High Efficiency Image Container, while BMP uses Bitmap Image. Compression: HEIC uses Lossy, while BMP uses None (uncompressed). Transparency: HEIC uses No, while BMP uses No.
Your HEIC file is decoded and re-encoded as BMP. Your HEIC file may contain HDR (High Dynamic Range) data. BMP only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.
Common misconception: ""Converting HEIC to BMP will improve the quality"" — in reality, no. heic has already permanently discarded data during compression. converting to bmp preserves what's left but cannot restore lost detail. the file will just be larger.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
Need to convert more than one file? Free users can do 5 per hour. Pro gets 100 per hour with files up to 5 GB each.
How to Convert HEIC to BMP

4. Download
Your .bmp file is ready. Download it directly or get all files as a zip archive.
What Happens When You Convert HEIC to BMP
Your HEIC image is decoded into raw pixel data, then re-encoded as BMP. Current quality is preserved as-is — no further degradation.
Your HEIC file is decoded — the compressed/stored pixel data is expanded into raw RGB pixels
HDR data is tone-mapped to standard dynamic range (8-bit per channel)
Pixels are re-encoded using no compression (raw pixel storage)
Metadata (EXIF, ICC profiles) is transferred where BMP supports it
The BMP file is saved and ready for download

Should You Convert HEIC to BMP?
When to Convert
- ✓Your HEIC file won't open on a recipient's device or in an application
- ✓A website, service, or platform only accepts BMP uploads
- ✓You captured this file on iPhone 7+ (iOS 11+) and need to share it with others
- ✓You need maximum device and software compatibility
When NOT to Convert
- ✗You're hoping to improve image/audio quality — converting lossy to lossless cannot recover lost data
- ✗You want to preserve HDR information — BMP only supports standard dynamic range
Common Mistakes When Converting HEIC to BMP
"Converting HEIC to BMP will improve the quality"
No. HEIC has already permanently discarded data during compression. Converting to BMP preserves what's left but cannot restore lost detail. The file will just be larger.
"BMP will be smaller than my HEIC file"
BMP uses no compression, so the output file is often larger than a lossy HEIC. If you need a small file, BMP may not be the right choice.
"My animated HEIC will stay animated after conversion"
BMP does not support animation. Only a single frame will be saved. Use WebP or GIF to preserve animation.
Frequently Asked Questions
Is HEIC to BMP conversion free?
Yes. CocoConvert offers free HEIC to BMP conversion with generous daily limits — 25 minutes of processing time and up to 5 files per hour (250 MB each). Pro plans remove these limits.
How fast is HEIC to BMP conversion?
Most files convert in 2–10 seconds depending on size. Large image files may take 30 seconds. Batch jobs process in parallel for maximum speed.
What happens to my files after conversion?
Your uploaded HEIC file and the converted BMP file are both automatically deleted from our servers within 24 hours. They are never shared, sold, or analysed.
Does converting HEIC to BMP lose quality?
Your HEIC file may contain HDR (High Dynamic Range) data. BMP only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.
Can I convert BMP back to HEIC?
Yes, CocoConvert supports BMP to HEIC conversion as well. However, if the original conversion involved lossy compression, converting back won't recover the lost data.
Versions are pinned in our worker Dockerfile and re-built via CI on every change.
